Greenfingers (2001)

Placed in an open prison program that provides prisoners with various types of skill training, convict Clive Owen discovers he has a knack for gardening. Loosely based on a true story, it’s a fairly charming, light hearted little British film. While there’s nothing terribly complex about the story, the acting meets the challenge with Owen receiving a patron in Helen Mirren, a love interest in Natasha Little, and a mentor in fellow inmate David Kelly.
