Despite his status as a major action star, Sylvester Stallone has made a number of attempts to remodel himself as a comic actor; one of his more infamous efforts in this direction was Stop! or My Mom Will Shoot!. Police detective Joe Bromowski (Sylvester Stallone) has just broken off his relationship with his girlfriend (and fellow police officer) Gwen Harper (JoBeth Williams), so Joe's mother Tutti (Estelle Getty) decides it's time to pay him a visit. Tutti proceeds to make Joe's life miserable by nagging him about his clothes, cleaning his apartment, washing his gun, tagging along on investigations, and somehow getting involved with a gun-running organization that the police have been trying to infiltrate. After this film, Stallone would stay away from comedy until 1997, when he played a cameo in another unenthusiastically received film, An Alan Smithee Film -- Burn, Hollywood, Burn.
