Saturday Night Live’s Dana Carvey stars as a small-time con man who impersonates an executive, in a comedy written by Mitchel Katlin and Nat Bernstein and directed by Donald Petrie (Mystic Pizza). The story, while familiar, has some comic possibilities, but Carvey manages to squelch them with leaden clowning and warmed-over impersonations (George Bush, a Japanese businessman) that never seem to be keyed to the surrounding movie. With Todd Graff, Julia Campbell, Milo O’Shea, James Tolkan, and Robert Loggia. (JR)
