If you, like the rest of the nerd and pop culture-minded population, are excited for the upcoming "Batman Vs. Superman" project, don't bother asking newly minted villain Jesse Eisenberg -- he's not talking.

Eisenberg, whose announced casting as bad guy Lex Luthor shocked audiences in late January, told MTV News that he was under strict orders to keep his mouth shut when it comes to the highly anticipated flick.

"I'm not allowed to say anything about anything for the next six years," he quipped during an interview in Miami promoting the upcoming "Rio 2," in which he voices a lovelorn bird on a tropical adventure.

Even though Eisenberg wouldn't say whether he would lose his signature shaggy locks for the role, we had no problem imagining a cue ball-headed Eisenberg.

Check out the clip above to hear why Eisenberg isn't allowed to call his mom back, and to see him as a baldie.
