Russell Crowe Open to a MAN OF STEEL Prequel

A lot of fans enjoyed Russell Crowe's portrayal of Jor-El in Man of Steel, and he was getting a lot of questions on Twitter asking him if he'd consider reprising his role in a prequel to the film. Here's his response, 

"A lot of you are asking about a KRYPTON prequel, if that's something you feel strongly about let @Legendary pictures know your thoughts."

He was then asked about it again and replied with the following,

"Just getting sick of reading the same question mate, however, if it came up, i'd give the tights another go."

I think a prequel set on Krypton could be really cool--I'd watch that movie! I don't think Warner Bros. would ever do it, as they are trying to figure out how to get there other DC comic book properties off the ground. Regardless, is a Man of Steel prequel with Crowe something you'd like to see happen?
