Almost all of Robin Cooks books concern themselves with a young intern (almost invariably female) who discovers a scientific conspiracy within a hospital and must challenge the medical establishment so that the truth may be known. All of Michael Crichtons books and films tend to be overrun by scientific detail where Crichtons recurrent message is that science is soulless and prone to human error. Both authors preoccupations coincide here in interesting ways. As always, Coma echoes with Michael Crichtons familiar message of science having gone out of control and occluded humanity. The most eerily fascinating scenes in the film are those set at the Jefferson Institute, which are designed with a gleamingly cool detachment images of naked bodies hanging on wires from the ceiling like marionettes. Here Crichton invokes an eerie futuristic fascination. (Wisely, Crichton lets these images stand on their own and avoids too much about how the whole operation is set up, as Richard Widmarks rambling explanation with reference to the advancement of science and a new medical elitism is so bizarre as to make no sense at all).
In many ways, Coma is a Gothic horror film at heart. It is really a Burke and Hare story in modern scientific drag in another film, Genevieve Bujolds heroine would be prowling the darkened hospital with candelabra and a low-cut night-gown. Michael Crichtons books come with an enormous degree of research placed into the particular subject he is writing about they frequently come with diagrams and graphs and here Crichton frequently lectures about what is going, which has a tendency to leave one feeling like they have just been hit by twenty volumes of medical encyclopedias. The detective story is okay but it is only when Crichton starts into full suspense mode that he and the film come into their own. A number of sequences like Genevieve Bujolds venture up into the pipe ducts of the hospital, the chase through the Jefferson Institute and a fine climax that plumbs at every persons fear of being helpless on a doctors table keeps one gripped.
The one good thing about Coma is that it has Genevieve Bujold at the centre of it. Bujold has such an elfin quality that she can still manage to convincingly play a 20 year old med student at the age of 36. Michael Crichton received much acclaim at the time for making Bujold a liberated heroine, although one would have had greater sympathy were Crichton not so willing to cast Michael Douglas as a chauvinist when it suits the moral point and then push such aside when he needs him to be the storys shining knight. Crichton also succeeds in improving on the book somewhat he adds the Nancy Greenly character as Genevieve Bujolds friend, which gives her character far better motivation in her quest (in the book, Susan became involved only after the death of a patient she tended).
The film was later disappointingly remade as the tv mini-series Coma (2012) with Lauren Ambrose in the role of Susan.
Michael Crichtons other works as director include: Westworld (1973) about an android amusement park that goes amok; The Great Train Robbery (1979) about a Victorian train heist; Looker (1981) about virtual models; Runaway (1984) about a police force to stop amok robots; and the courtroom thriller Physical Evidence (1989). Films adapted from Crichtons books include the extra-terrestrial virus film The Andromeda Strain (1971); the neurosurgical Frankenstein film The Terminal Man (1974); Jurassic Park (1993); Rising Sun (1993), a superior adaptation of Crichtons blatantly racist book about Japanese business practice; Barry Levinsons adaptation of Disclosure (1994), Crichtons novel about sexual harassment, which contains some sf elements; the lost world film Congo (1995); The Lost World: Jurassic Park (1997); Levinsons underrated Sphere (1998) about the investigation of a crashed UFO; John McTiernans The 13th Warrior (1999), an historical epic about the meeting between Vikings and Neanderthals; Richard Donners dull adaptation of Crichtons Timeline (2003) about time travel to Mediaeval France; the tv mini-series remake of The Andromeda Strain (2008); and the tv mini-series remake of Westworld (2016 ). Crichton also created the hit hospital drama ER (1996-2009) and wrote the original screenplay for Twister (1996) about tornado chasers.
Other films adapted from Robin Cooks works have been the tv movies Harmful Intent (1993), Mortal Fear (1994), Virus (1995), Terminal (1996), Invasion (mini-series, 1997) and Acceptable Risk (2001). The only other cinematically released Robin Cook adaptation has been Sphinx (1981) from one of Cooks rare non-medical books, which is a thriller about Egyptology.
