I can't place the movie. I've never seen it.
EDIT: Maybe it's "Cashback " (2006)
Director: Sean Ellis
Ben Willis (Sean Biggerstaff) appreciates beauty. So much so that he can freeze time, strip beautiful strangers naked and ‘appreciate’ them at his leisure. But Ben’s voyeuristic passion is not an invasion of privacy, because he is an artist and therefore capable of feeling, seeing and, yes, appreciating women more vividly than the rest of us.
