Sacha Baron Cohen?
Was that Savha Baron Cohen (he of Ali G & Borat fame) playing the blind Rabbi?
Curiously enough, it does not mention reference to his name or the character in the film's listing information.
No it wasn't and it didn't really look like him either.
I can't remember what his name was but he was credited at the end of the film, I don't know why he isn't on the listing here. He just reminded me of Ron Moody in Oliver.
