Deep Impact is a 1998 sci-fi-drama disaster film released by Paramount Pictures and DreamWorks SKG in the United States on May 8, 1998. The film was directed by Mimi Leder, and stars Elijah Wood, Téa Leoni, Morgan Freeman, Leelee Sobieski, Vanessa Redgrave and Robert Duvall. The plot describes the attempts to prepare for and destroy a fictional comet (named "Wolf-Biederman"), which is expected to collide with the Earth and cause an Extinction Level Event.
A competing "space impact" film, Armageddon, was released about two months after Deep Impact in the United States. Deep Impact was lauded by astronomers as being more scientifically accurate, but Armageddon fared better at the box office.
As a consequence of Lerner's investigation, the government decides to make the knowledge public. U.S. President Tom Beck (Freeman) announces the grim facts: the comet, named "Wolf-Biederman," is seven miles (11 km) wide, large enough to destroy civilization if it strikes Earth. The USA and Russia will dispatch a crew of astronauts on the spaceship Messiah to destroy the comet, using nuclear weapons. In order to prevent opportunism, Beck freezes all wages and prices. Life changes drastically worldwide, and Biederman and Lerner both become celebrities.
Messiah is constructed in orbit, and the crew use the Space Shuttle Atlantis to reach it. When the astronauts travel to the comet and drill the bombs into the surface they lose one crew member in the process and another is seriously burned by sunlight. When the bombs are detonated, the vessel is slightly damaged and the crew's contact with Earth is cut off. The comet is not destroyed; instead, it splits into two chunks, one much smaller than the other. President Beck acknowledges Messiah’s failure and announces that special underground shelters have been built in limestone caves of Missouri.
The government will conduct a lottery to select 800,000 ordinary Americans to join 200,000 pre-selected scientists, engineers, bankers, plumbers, teachers, actuaries lawyers, artists, soldiers, accountants and officials. These people will be part of a worldwide effort to save mankind from extinction. Beck declares martial law as the lottery's selectees are notified. Jenny and Leo are both among the pre-selected. Leo gets permission to marry Sarah, to save her and her family, but on evacuation day, the soldiers have no record of the agreement to save Sarah's parents and sister. Sarah refuses to leave without them. Leo later manages to locate Sarah and her family on a gridlocked freeway. He takes Sarah and her infant sister to higher ground in the Appalachian Mountains. Meanwhile, as MSNBC is being evacuated by helicopter, Jenny gives her seat to a co-worker with a young daughter and goes to be with her estranged father.
A last-ditch effort to use all of Earth's missile-borne nuclear weapons to destroy the comets fails. The smaller of the two ("Biederman") hits the Atlantic Ocean near Virginia Beach and Cape Hatteras, creating a megatsunami about 1,000 to 3,500 ft high. Jenny and her father perish, along with Sarah's parents and millions of others on America's east coast, Europe, and Africa.
The world then braces for the impact of the larger comet, "Wolf," which is predicted to strike western Canada and create a cloud of dust that will block out the sun for two years, killing all remaining plant, animal, and human life aside from that evacuated to the caves.
The crew members of Messiah decide to try to destroy the comet by flying into a fissure that has formed on its surface and exploding the remaining bombs on board. They will all die in the process, and have only enough time to say goodbye to their families. Messiah does succeed in breaking up "Wolf" into small pieces that burn up entering Earth's atmosphere, saving humanity. Afterward, President Beck gives an inspirational speech in front of the United States Capitol which is being rebuilt, in which he urges the nation to begin its recovery and efforts to rebuild.
In 2005, Paramount's parent company, Viacom, announced its acquisition of DreamWorks, and completed it in early 2006. Around that time, Viacom split into two companies, the other being called CBS Corporation. CBS inherited Paramount's TV operations, now called CBS Paramount Television.
Today, worldwide video and theatrical rights to Deep Impact are with Paramount, while television rights are in the hands of CBS Television Distribution.
CNN was originally going to be the Cable News Network in which Jenny Lerner's (Tea Leoni) plot revolves around. CNN rejected this because it would be "inappropriate". MSNBC, which was a new network at the time, is featured in the movie instead.
