As of September 2015, the six movies with the highest worldwide box office gross revenues are "Avatar," "Titanic," "Jurassic World," "The Avengers," "Furious 7" and "Avengers: Age of Ultron." This list gives more weight to recent films, because it does not take into account inflation and rising movie theater ticket prices. The six highest-grossing films adjusted for inflation by Guinness World Records are "Gone With the Wind," "Avatar," "Star Wars," "Titanic," "The Sound of Music" and "E.T. the Extra-Terrestrial."
The list of the top six highest-grossing pictures changes when taking into account only domestic box office revenue. In the United States, the six highest-grossing films are "Avatar," "Titanic," "Jurassic World," "The Avengers," "The Dark Knight" and "Star Wars: Episode I The Phantom Menace."
The order of the highest-grossing films list can change when home video and television income is added. For example, "Titanic" earned $1.2 billion from video and DVD sales and rentals in addition to the $2.2 billion it grossed in theaters. "Titanic" also earned $55 million from the NBC and HBO television broadcast rights.
A film's merchandising and adaptations can account for more revenue than the original film's box office. For instance, "The Lion King" made over $2 billion in box office and home video sales, but its stage adaptation has earned $6 billion worldwide. "The Lion King" has also sold $3 billion of merchandise.
