“What came out of 'The LEGO Movie' was the idea of 'Batman's the Dark Knight', so why is he so moody? What's going on? Why is he so banged up? And wouldn't it be fun to get in there and explore that?”

“This might be controversial, but sometimes I think that being happy is a decision. I don't mean that in a way to diminish clinical depression. But on a more day-to-day level.”

“With 'Mutant Ninja Turtles,' I wanted to play a character who lives more in the real world, although yes, I grant you, he immediately encounters, um, turtles, of the teenage mutant ninja variety.”

“Batman is basically an ordinary guy who had something tragic happen to him when he was young.”

“Batman is pretty much a self-trained guy. I think it would be fun to do a character like Superman or Captain Marvel or maybe Green Lantern, somebody who's got a completely different resource for fighting crime and fighting villains.”

“Batman had a certain speech pattern that I established because he was always Sherlock Holmes-ian. He was Basil Rathbone. In other words, he was always musing about something.”
