Coma is a 1978 suspense film based on the novel of the same name by Robin Cook. The film rights were acquired by director Michael Crichton, and the movie was produced by Martin Erlichmann for Metro-Goldwyn-Mayer. The cast included Geneviève Bujold, Michael Douglas, Elizabeth Ashley, Richard Widmark, and Rip Torn. Among the actors in smaller roles are Tom Selleck and Ed Harris. The film is in color with stereo sound and runs for 113 minutes. It is notable for the intense paranoia which pervades the film, similar to other films of the 1970s such as Invasion of the Body Snatchers, The Conversation, The Stepford Wives, and earlier, Rosemary's Baby. Susan Wheeler (Geneviève Bujold) is a surgical resident at Boston Memorial Hospital, a close analogue of Massachusetts General Hospital. Wheeler is devastated when her best friend is pronounced brain dead and ends up in a coma after minor surgery at the hospital. Looking at the records, Susan finds that over the previous year a number of other fit young people have ended up the same way.
