Last year at San Diego Comic-Con, Daniel Radcliffe pulled one over on us -- quite literally, actually -- when he hit the convention center floor disguised as Spider-Man:

So when Radcliffe visited MTV News HQ to promote "Victor Frankenstein" with James McAvoy this year, we had to ask him what the plan was this year.

"I don't think I'm going to have time this year," he replied. "I don't know. I don't want to say no, because I kind of want to say that I might be The Flash, and then have everyone who's The Flash get just ambushed on the floor."

McAvoy seemed to love this idea, and Radcliffe continued by instructing fans on what might happen when the encounter "Daniel Radcliffe's Flash" on the floor.

"When you grab me and shake me I'll say no," he continued. "I might put on an American accent and I might look a different body type, but..."

You heard it here first, folks. Go find that Flash!
