Unknown White Male

I watched this movie last night. I've heard the rumors that this was a fake documentary, and I could definitely see how one could think that. There does seem to be something fake about the whole thing, like either a) the subject, Doug Bruce, was faking losing his memory and duped everyone around him or b) everyone in the documentary was in on it and they were all just acting. The family didn't seem emotional enough to me. And why did he agree to videotape his ordeal? And how does he know some things but not others? He recognizes people speaking Russian but he doesn't know what it feels like to swim in the ocean? But I think the parts that convinced me that it wasn't a total fake were seeing how he acted compared to his old friends. Something in his eyes, childlike. Innocence compared to their cynicism.
