I like Jim Brown, but I never could figure that one out. I agree with the truckload of morons in the movie, Canadian Bacon, on this issue. I know you are supposed suspend your disbelief, when you watch a movie,  but are you supposed to have frontal lobotomy?

No mater what one can or can't say about Jim Brown as an actor, it was simply forced casting at its height to cast an African-American as a spy or special ops agent in Nazi Germany.

Yeah, there were some real brain-trusts back in Special Ops in the Second World War, sending a black guy to infiltrate a Nazi hideout.

He'd fit right in in a Waffen SS outfit.
