Nuns on the Run (1990)

Synopsis
Eric Idle and Robbie Coltrane team up for this bad boy comic burlesque, directed by Jonathan Lynn. Idle and Coltrane play Brian Hope and Charlie McManus, a pair of two-bit hoods who want to go straight, repulsed by the increasing reliance on guns and violence in their line of work. In thrall to vicious gangster Case Casey (Robert Patterson), the duo determine that their next job will be their last. When a large amount of money is extracted from a gang of Hong Kong drug dealers and it falls into the laps of Brian and Charlie, the two take off with the loot, with the Chinese Triad and Casey in relentless pursuit. When their car runs out of gas in front of a convent, Brian and Charlie run inside and disguise themselves as two of the ugliest nuns imaginable. Inside the convent, Brian and Charlie pass themselves off as nuns from a different order, assigned to the convent before leaving the country on missionary work. As the two men enjoy their undercover work with a collection of nubile nuns and coeds, the bad guys close in on their trail. ~ Paul Brenner, All Movie Guide
