I watched this movie on BBC2 when it first came out (March 2011) and it was fantastic. Matt Smith's portrayal of an Englishman moving to Berlin to experience the gay scene was great.
The storyline is about the English-American author Christopher Isherwood, and chronicles his life as he moves to Berlin and has a string of affairs, finally meeting the boy of his dreams, Heinz. Unfortunately the Nazi war interferes with their lives.
A great movie to watch, especially those who like Matt Smith.
