The film stars Daniel Radcliffe as Harry Potter, alongside Rupert Grint and Emma Watson as Harry's best friends Ron Weasley and Hermione Granger. The adult cast features Richard Harris, Maggie Smith, Robbie Coltrane, Alan Rickman and Ian Hart.
Warner Bros. bought the film rights to the book in 1999. Production began in 2000, with Columbus being chosen from a short list of directors to create the film. Rowling insisted that the entire cast be British, in keeping with the cultural integrity of the book and the film. Rowling also approved the screenplay, written by Steve Kloves. The film shot primarily at Leavesden Film Studios, as well as historic buildings around the country, and was released in the United Kingdom and the United States in November 2001. Along with mostly positive critical reception, it made in excess of $976 million at the worldwide box office and received three Academy Award nominations. The second, third, fourth, and fifth books have also been adapted into successful films, with the sixth and seventh confirmed.
Harry defies his aunt and uncle, and attends Hogwarts where he begins to learn magic and make new friends, as well as enemies, among the Hogwarts students and staff. Voldemort has been near death, and in hiding, since the attack on Harry ten years earlier, but a plot is brewing for the dark lord to regain his power and strength through the acquisition of a philosopher's stone, which grants immortality to its owner. Harry and his friends, Hermione Granger and Ron Weasley, discover the plot and seek to prevent the theft of the stone, which is hidden in a protected chamber at Hogwarts.
Although Steven Spielberg initially negotiated to direct the film, he declined the offer. Spielberg reportedly wanted the adaptation to be an animated film, with American actor Haley Joel Osment to provide Harry Potter's voice, or a film incorporated elements from subsequent books as well. Spielberg contended that, in his opinion, there was every expectation of profit in making the film, and that making money would have been like "shooting ducks in a barrel. It's just a slam dunk. It's just like withdrawing a billion dollars and putting it into your personal bank accounts. There's no challenge. In the Rubbish Bin section of her website, Rowling maintains that she has no role in choosing directors for the films and said "Anyone who thinks I could (or would) have 'veto-ed' him [Spielberg] needs their Quick-Quotes Quill serviced. Heyman recalled that Spielberg decided to direct whichever project, out of Artificial Intelligence: A.I., Minority Report, Memoirs of a Geisha or Harry Potter, "came together first," with him opting to direct A.I..
After Spielberg left, talks began with other directors, including: Chris Columbus, Terry Gilliam, Jonathan Demme, Mike Newell, Alan Parker, Wolfgang Petersen, Rob Reiner, Ivan Reitman, Tim Robbins, Brad Silberling, M. Night Shyamalan and Peter Weir. Petersen and Reiner then both pulled out of the running in March 2000, and the choice was narrowed down to Silberling, Columbus, Parker and Gilliam. Rowling's first choice director was Terry Gilliam, but Warner Bros chose Columbus, citing his work on other family films such as Home Alone and Mrs. Doubtfire as influences for their decision. Columbus pitched his vision of the film for two hours, stating that he wanted the Muggle scenes "to be bleak and dreary," but those set in the wizarding world "to be steeped in color, mood, and detail." He took inspiration from David Lean's adaptations of Great Expectations and Oliver Twist, wishing to use "that sort of darkness, that sort of edge, that quality to the cinematography," taking the colour designs from Oliver! and The Godfather.
| "Harry Potter is the kind of timeless literary achievement that comes around once in a lifetime. Since the books have generated such a passionate following across the world, it was important to us to find a director that has an affinity for both children and magic. I can't think of anyone more ideally suited for this job than Chris." |

Steve Kloves was selected to write the screenplay for the film. He described adapting the book as "tough", as it did not "lend itself to adaptation as well as the next two books." Kloves was sent a selection of synopses of books proposed as film adaptations, which he "almost never read", but Harry Potter jumped out at him. He went out and bought the book, and became an instant fan of the series. When speaking to Warner Bros. he stated that the film had to be British, and had to be true to the characters. Kloves was nervous when he first meet Rowling as he did not want her to think he was going to "[destroy] her baby." Rowling admitted that she "was really ready to hate this Steve Kloves," but recalled her initial meeting with him: "The first time I met him, he said to me, 'You know who my favourite character is?' And I thought, You're gonna say Ron. I know you're gonna say Ron. But he said 'Hermione.' And I just kind of melted." Rowling received a large amount of creative control, being made an executive producer, an arrangement that Columbus did not mind.
Warner Bros. had initially planned to release the film over the 4 July 2001 weekend, making for such a short production window that several proposed directors pulled themselves out of the running. However due to time constraints the date was put back to 16 November 2001.
Two British film industry officials requested that the film be shot in the UK, offering their assistance in securing filming locations, the use of Leavesden Film Studios, as well as changing the UK's child labour laws. Warner Bros. accepted their proposal and filming began in October 2000 at Leavesden Film Studios, and concluded in April 2001, with final work being done in July. Principal photography took place on 2 October 2000 at Goathland railway station in North Yorkshire. Canterbury Cathedral and Inverailort Castle in Scotland were both touted as possible locations for Hogwarts; Canterbury rejected Warner Bros. offer due to concerns about the film's "pagan" theme. Alnwick Castle and Gloucester Cathedral were eventually selected as the principal filming locations for Hogwarts, with some scenes also being filmed at Harrow School. Other Hogwarts scenes were filmed in Durham Cathedral over a two week period, these included shots of the corridors and filming for some classroom scenes. Oxford Divinity School served as the Hogwarts Hospital Wing, and the Duke Humfrey Library was used as the Hogwarts Library. Filming for Privet Drive took place on Picket Post Close in Bracknell, Berkshire. Filming on the street took two days, with the producers only having planned for one, the delay meant that they had to pay the street's residents more money than they had anticipated. As such, for all of the subsequent film's scenes set in Privet Drive, filming took place on a constructed set in Leavesden Film Studios, which proved to have been cheaper than filming on location. Australia House in London was selected as the location for Gringotts Bank, whilst Christ Church, Oxford was the location for the Hogwarts trophy room. London Zoo was used as the location for the scene in which Harry accidentally sets a snake on Dudley, with Kings Cross Station also being used as the book specifies.
Due to the film's title difference in America and the United Kingdom, all scenes that mention the stone had to be filmed twice, once with the actors saying "philosopher's" and the second with them saying "sorcerer's". The children spent their days filming for four hours and then doing three hours of schoolwork, as well as all developing a fondness for having fake facial injuries added to them by the makeup staff. Radcliffe had to wear green contact lenses as, unlike Harry's, his eyes are blue. In some scenes computer animation was used to paint his eyes green, due to Radcliffe's discomfort.
Columbus originally planned to use both animatronics and CGI animation to create the magical creatures in the film, including Fluffy. Nick Dudman, who worked on Star Wars Episode I: The Phantom Menace, was given the task of creating the needed prosthetics for the film, with Jim Henson's Creature Shop providing creature effects. John Coppinger stated that the magical creatures that needed to be created for the film had to be designed multiple times. The film features nearly 600 special effects shots, with numerous companies handling different things. Industrial Light & Magic created the face of Lord Voldemort on the back of Quirrell, Rhythm & Hues animated Norbert; and Sony Pictures Imageworks produced the film's Quidditch scenes.
John Williams was selected to compose the film's score. Williams composed the score at his homes in Los Angeles and Tanglewood before recording it in London in August 2001. One of the main themes is entitled "Hedwig's Theme", Williams retained it for his finished score as "everyone seemed to like it".
Rik Mayall was cast in the role of Peeves, having to shout his lines off camera during takes, but the scene ended up being cut from the film.
Even so, as with many book to film transitions, there are differences between the plot of the film and the original source material. The first chapter of the book begins from the point of view of Vernon and Petunia Dursley in the very day before they are given Harry to look after, highlighting how Muggles react to magic. The film scraps this, beginning with Professor Dumbledore, Professor McGonagall and Hagrid leaving Harry with the Dursley's. Next, a month of Harry's summer, including several of Vernon's attempts to escape the constantly arriving Hogwart's letters and his less than pleasant times at Mrs. Figg's, is cut from the film while the Boa Constrictor from Brazil in the zoo becomes an Anaconda from Burma in the movie. Some conflict between Harry and Draco, including their original first meeting in Madam Malkin's robe shop, is not included. The character of Piers Polkiss is cut and some of Nicolas Flamel's role is changed or cut altogether. Norbert is mentioned to have been taken away by Dumbledore in the film; whilst the book sees Harry and Hermione have to take him by hand to friends of Charlie Weasley. Rowling described the scene as "the one part of the book that she felt [could easily] be changed." As such, the reason for the detention in the Forbidden Forest is also changed. In the novel, Harry and Hermione are put in detention for being caught by Filch when leaving the Astronomy Tower after hours, while in the film, Harry, Ron, and Hermione are put in detention because Malfoy caught them in Hagrid's hut after hours. The Sorting Hat's song is axed, as is Snape's potion riddle task and Quirrell's troll room on the way to the stone. Visual changes included both Aunt Petunia and Dudley being made brunette, and Firenze, who in the book is described as being palomino with light blonde hair, is shown to be dark in the film. Additionally the Quidditch pitch is altered from a traditional stadium to an open field circled by spectator towers.
Richard Corliss of Time, considered the film a "by the numbers adaptation," criticizing the pace and the "charisma-free" lead actors. CNN's Paul Tatara found that Columbus and Kloves "are so careful to avoid offending anyone by excising a passage from the book, the so-called narrative is more like a jamboree inside Rowling's head. Ed Gonzalez wished that the film had been directed by Tim Burton, finding the cinematography "bland and muggy," and the majority of the film a "solidly dull celebration of dribbling goo.
The film had its world premiere on 4 November 2001, in Leicester Square, London; with the cinema adapted to have a Hogwarts design. Harry Potter was greatly received at the box office. In the United States it made $33.3 million on its opening day, breaking the single day record previously held by Star Wars Episode I: The Phantom Menace. On Saturday, the second day of release, the film increased to $33.5 million breaking the record for biggest single day once again. In total it made $90.3 million during its first weekend, breaking the record for highest opening weekend of all time that was previously held by The Lost World: Jurassic Park. Harry Potter held the record until the following May when Spider-Man made $114.8 million in its opening weekend. Similar results were achieved across the world. In the United Kingdom it broke the record for the highest opening weekend ever, both including and excluding previews, making £16.3 million with and £9.8 million without previews. The film went on to make £66.1 million in the U.K. alone, making it the second highest-grossing film of all-time in that country, which it remains to this day.
In total, the film earned $976.5 million at the worldwide box office, $317.6 million of that in the U.S. and $658.9 million elsewhere, which made it the second highest grossing film in history at the time, as well as the highest grossing of the year. As of 2008, it is the unadjusted fifth highest-grossing film of all-time, behind Titanic, The Lord of the Rings: The Return of the King, Pirates of the Caribbean: Dead Man's Chest, and The Dark Knight.
The film received three Academy Award nominations: "Best Art Direction", "Best Costume Design", and "Best Original Score" for John Williams although it did not win in any category. The film was also nominated for seven BAFTA Awards, including Best Supporting Actor for Robbie Coltrane. The film won a Saturn Award for its costumes and was nominated for eight more. It won other awards from the Casting Society of America and the Costume Designers Guild. It was nominated for the AFI Film Award for its special effects and the Art Directors Guild Award for its production design.
