My Blue Heaven (1990)

Synopsis
Herbert Ross directed this Nora Ephron-scripted buddy comedy starring Steve Martin, Rick Moranis, and Joan Cusack. Steve Martin plays Vinnie Antonelli, a street smart mobster who agrees to turn state's evidence and is forced to move to Fryburg, California as part of the witness relocation program. Rick Moranis plays the nebbish FBI agent Barney Coopersmith, who is assigned to help Vinnie adjust to small town life. Instead, Vinnie helps Barney come out of his shell, much to the consternation of divorced mother and relentless district attorney Hannah Stubbs (Joan Cusack). ~ Paul Brenner, All Movie Guide
