Terrific paranoid thriller from writer/director Michael Crichton. Geneviève Bujold plays a doctor investigation a mystery around what's happening to otherwise healthy patients lapsing into comas. She's helped by her skeptical boyfriend, fellow doctor Michael Douglas, but she's really on her own uncovering a creepy conspiracy. The mystery of what's happening to the patients is the weakest element of the film, but the acting, tense direction, and smartly written script allows the audience to gloss over the obviousness of the mystery. It also helps that I'm a big fan of 1970s paranoid conspiracy thriller like "Winter Kills" or "The Parallax View," which I believe grew out of Watergate. Conspiracy films and television shows made a resurgence in the 90s with "The X-Files," "JFK," and so on. I think our current political climate is now ripe for another resurgence of the paranoid conspiracy thriller. But I digress. Rip Torn, Richard Widmark, Lois Chiles, Tom Selleck, Joanna Kerns, and Ed Harris in his film debut all appear in the film. And Jerry Goldsmith provides a fine score for the film.
