Yeah I couldn't understand a word from that. I watched it 3 times and he still don't know what he sounds like.
You couldn't understand Batman either? It's pretty clear to me.
Batman: "You used to run from me in fear"
Mr. Freeze: "A mistaken impression on your part"
Batman: "You're going to wish you had".
Mr. Freeze is speaking in a pretty distinct Austrian/German accent. He sounds like a Bond villain.
