This is a very interesting movie. It's classified as sci-fi. Technically it is, but it is not sci-fi in a traditional sense. It's about a man, leaving his friends after 10 year of teaching. At his farewell party he tells them that he is a cro-magnon man. The entire movie is the discussion/argument that follows. How can he prove his case? How can they disprove it?
Except for a few shots, the entire thing takes place inside a small cabin. Intimate camerawork reenforces the feeling of being close. The dialog, and limited set makes the film feel as if it were written for the stage. Think "Deathtrap".
The actors are not A-list, but if you watch a lot of television/movies you'll no doubt recognize most of them. The quality of the performances are what you would expect from a made for TV movie. Still, for a low budget indie film, actors aren't always given the time needed to stretch those muscles as it were. The performances never hold back the story.
I'm putting this on my "watch again" list.
