The Siege is a 1998 American action thriller drama film directed by Edward Zwick. The film is about a fictional situation in which terrorist cells have made several attacks on New York City. The film stars Denzel Washington, Annette Bening, Tony Shalhoub and Bruce Willis as the U.S. Army Major General William Devereaux.

Following the bombing of an American military installation in the Middle East (the film shows footage from the 1996 Khobar Towers bombing), the U.S. government orchestrates the capture of the mastermind believed to be behind the attack, Sheikh Ahmed bin Talal. In New York City FBI Special Agent Anthony Hubbard (Washington) and his Lebanese-American partner Frank Haddad (Shalhoub) are told of a hijacked bus, fully loaded with passengers and containing an explosive device. The bomb turns out to be a paint bomb and the terrorists manage to escape. The FBI receives demands to release the sheikh.
