Seth Rogen was on hand at Comic-Con to talk about his role in Kevin Smith's Zack and Miri Make a Porno. Rogen and the rest of Miri cast was in a pretty jokey mood after a day of Comic-Con promotion. Thankfully, we did get him to discuss Green Hornet just a bit.

With production getting closer, I asked Rogen whether he's started training for the action-heavy role. "I go beat up three guys every night just in bars and s***," Rogen jokes. "I just knock people's hats off. Not yet really. I've worked out around four times. As you can see, it's done wonders." Rogen points to his gut.

"A complete transformation has occurred," he laughs. "I actually did Karate for year when I was young, almost ten years. Me and [Jason] Mewes (Zack and Miri co-star) fought early. He kicked my a**. My a** is tighter, it doesn't look any better though."

"I need to get into some better shape than this just for life, just to live." (Laughs)

As for a Green Hornet start date, nothing is set just yet. "Not officially," Rogen confirms. "We don't have a director or anything. We've started meeting with people. That has started."

So who's on the short list for director and cast? "I can't tell you that. You are!" Rogen says with his trademark guffaw.

More to come on Green Hornet as we hear it.
