A lonely Chicago subway cashier (Sandra Bullock) saves a commuter (Peter Gallagher) from a speeding train, and while he remains in a coma she’s mistaken for his fiancee and virtually adopted by his family. The plot of this 1995 romantic comedy, directed by Jon Turteltaub (Cool Runnings) from a script by Daniel G. Sullivan and Fredric Lebow, is pretty stupid throughout, and the filmmakers show no compunction in shaking its silliness in your face, but the film’s casual warmth may make you tolerate some of the shortcomingsespecially since Bullock seems to be having such a fine time with her first starring role. With Bill Pullman, Peter Boyle, Glynis Johns, and Jack Warden. 103 min. (JR)
