40 Years old is too early of a cutoff for Penguin... There's no actors I like for the role under 40... My first choice is still Ray Winstone... I also like Mark Sheppard and seeing that manip above makes me more interested in Serkis in the role. I don't see why they would ever cast a Penguin in his 20's, so that age range that is rumored makes no sense.
I really hope they don't screw this casting up, Penguins my second favorite Bat Villain and I don't want another crap DC Villain after having to live through EisenLex and LetoJoker...
