In exchange for being allowed to make his directorial debut in Grand Theft Auto, Ron Howard agreed to take no salary as a director, merely as star and co-screenwriter (with his dad Rance). The plot finds Sam Freeman (Howard) eloping with his heiress girlfriend Paula Powers (Nancy Morgan). Her mob-connected dad Bigby Powers (Barry Cahill) vehemently opposes the marriage, and isn't about to change his mind now that Sam has stolen his Rolls-Royce and sped off to Las Vegas with his daughter in tow. Marion Ross, Howard's Happy Days mom, turns in an offbeat supporting characterization.
