Klaus Kristin is his real name, and he’s actually the hybrid son of a male yeti and a human woman. Not a happy home-life then, but on the plus side, he does have control over both ice and snow. Cool. So to speak…
Why He Won’t Appear:
We already had Arnie as Mr. Freeze, and God knows that was enough for anyone.
How Nolan Could Make Him Work:
Nolan could do an excellent, pun-free version of the tragic Mr. Freeze, but the Snowman is a different matter. Maybe re-writing him as a Russian henchman who’s impervious to cold could work, although even then, it sounds more Schumacher than Nolan.
