Two excellent films: The History Boys (on video) and Atonement (in the cinemas still). The first is written by Alan Bennett and "sparkles with wit and charm", not to mention much discussion of complex male sexuality. The second adapted from Ian McEwan's novel, has straightforward sexuality, but an excellent exploration of false testimony, guilt and attempted atonement. It also has the most amazing tracking shot I've ever seen - a full 10 minutes where the camera and the leading actors must have travelled over half a mile on foot.
