I'm surprised to see this listed as a 1995 movie, because it's a "new release" in the video stores and the film's case has a date of 1999. I agree with Dick 108's review heartily. The acting is very good, and the story is interesting. Like Dick, I was intrigued and researched, on the 'Net, Peter Warlock, and found the the movie seems far from the truth. It may have been based on a book or article by one of Heseltine's friends, a Mr. Gray. More I won't say, because I don't want to spoil things for someone reading this before seeing the movie. The actor, Jeremy Northam, looks exactly like him.
