Keeping Mum is a 2005 British black comedy film co written and directed by Niall Johnson and starring Rowan Atkinson, Kristin Scott Thomas, Maggie Smith and Patrick Swayze.

When a young pregnant woman named Rosie Jones boards a train, her enormous trunk starts leaking blood in the luggage compartment.

Forty-three years later, Walter Goodfellow, the village vicar of Little Wallop, is very busy writing the perfect sermon for a Church of England convention.

He's completely oblivious to his family's problems: his wife, Gloria, has unfulfilled emotional/sexual needs and starts an affair with her golf instructor, Lance; his daughter, Holly, has a growing sex drive and physical maturity and is constantly changing boyfriends; and his son, Petey, is being bullied at school.

Walter talks to Bob and Ted, the two waterworks employees who have been working quietly in the background on the vicarage's pond during recent events.

The site's critical consensus reads, "The stellar cast, including Kristin Scott Thomas and Dame Maggie Smith, is certainly an asset, but this black comedy is too uneven.
