I (U.S. title: The Passionate Sentry )is a 1952 British comedy film directed by Anthony Kimmins and starring Nigel Patrick, Valerie Hobson and George Cole.

The film depicts the farcical activities of the various inhabitants of a grace and favour house near St James's Palace in Central London.

[3] Sir Hubert Cornwall is a member of the royal household and lives with his adult children Miles and Alex in a grace and favour house.

One weekend, noticing the house is empty, Queen's Guard sentry Arthur Crisp installs his ex-girfriend there while she recovers from an accident.

[5] The Monthly Film Bulletin wrote: "Made in the canned style of Home at Seven, this traditional British farce is a rather more competent exampie of much staple fare in the '30s, It s all very larkish and class-conscious, charaded to the manner born by Nigel Patrick, Valerie Hobson, and A. E. Matthews, and with distinct unease by Anthony Bushell, Peggy Cummins and George Cole.
