Skyjacked is a 1972 disaster film, directed by John Guillermin. The film stars Charlton Heston, James Brolin, and Yvette Mimieux, along with an all-star cast primarily playing the roles of passengers and crew aboard an airliner. Skyjacked is based on the David Harper novel, Hijacked. This was the last of actress Jeanne Crain's 64 films. This was also the film debut for several actors and actresses: Susan Dey, who was known for her work in The Partridge Family television series (later L.A. Law), along with Roosevelt "Rosey" Grier, a former NFL defensive tackle. Skyjacked was an example of the Hollywood "disaster" film, as well, it also very much fits the additional genre of the complex, heavily character-driven ensemble cast picture. The film explores the personal dramas and interactions that develop among the passengers and crew as they deal with a hijacker and his demands. During a routine flight to Minneapolis, a passenger (Susan Dey) aboard Global Airways Flight 502, a Boeing 707, discovers a bomb threat written on the mirror of one of the first-class bathrooms. A second threat is soon found left in a galley. Captain Henry O'Hara (Charlton Heston) takes the cryptic threats seriously and follows the instructions: "Bomb on plane divert to Anchorage Alaska. No Joke, No Tricks. Death." by changing course for Alaska. To avoid an explosive decompression if a bomb goes off, he flies at lower altitude, increasing fuel consumption.
