Although his real name in the comics is Victor Fries, on the TV show it was Dr. Shimmel. (edit) This is the final appearance of George Sanders as Mr. Freeze. (edit) George Sanders at one time was married to Zsa Zsa Gabor, who would later play the villainess Minerva in the final episode Minerva, Mayhem and Millionaires. (edit) Dr. Vince is an obvious spoof on the 1961-66 ABC medical drama Ben Casey. (edit)

Batman: Mr. Freeze. Give yourself up. We can get help for you. Medical help!
Mr. Freeze: In prison? This I do not believe. No, you must pay for what you did to me. For forcing me to live like this. Never again to know the warmth of a summer breeze. Never to feel the heat of burning logs in vintertime. Revenge. That is what I need! Revenge! I will have revenge!
(edit)

This episode features one of the scant few times that Robin actually disobeys an order from Batman. (edit) Despite the fact that no one but Mr. Freeze can survive in the extreme cold of his hideout, his Butler seems to have managed it when he handed Freeze his sherry, as his hand can clearly been seen placing the glass down outside of the warm red area.
