It's one big (green) thumbs-up for this affecting true-life tale about hardened con Colin Briggs (Clive Owen), a small-time criminal who gets a new lease on life -- behind prison bars -- as an award-winning gardener. Standing out in supporting roles are David Kelly as a prisoner chum of Briggs's who coaxes him out of his shell and Helen Mirren as a world-class horticulturalist who worries when her daughter falls for Briggs.
