Hancock The Sequel???

Little over a year after "Hancock" and its superpowered slacker namesake started gobbling up $628 million in worldwide box office sales, movement on a sequel has begun to pick up. With Peter Berg set to return as director, two new writers hired to pen the script and star Will Smith consulting on the story, all the key players seem to be falling into place.

Yet we haven't actually heard for certain that Smith and co-star Charlize Theron will definitely reprise their roles. In a conversation before he heads to the Toronto film festival with a Wayne Gretzky documentary, Berg confirmed for MTV News that both Smith and Theron will certainly be returning for more "Hancock" hero-dom.

"Everybody's going to come back for a sequel," Berg said in response to a question about the two megastars.

Berg's comments confirm what Theron told us last September when she said she'd happily return if the rest of the key players returned too.

"Riding the Will Smith train is a really nice train to ride!" she laughed.

The big reveal at the end of "Hancock" was that [Spoiler Alert!] both Smith and Theron's characters are immortal gods who become vulnerable when near each other. For the sequel, Berg said we can expect the appearance of at least one more all-powerful god. What's more, he's got his eye on a well-known name to play a third superhero.

"We have [someone in mind]," Berg said. "I'm not gonna tell you who, but we have!"
