Here’s the latest scoop on the sequel buzz spreading across Hollywood:

Zombieland: Prepare for another attack of the walking dead—this time in 3D. Sony has already greenlighted a follow-up to Zombieland, the recent comedy starring Woody Harrelson and Jesse Eisenberg. “Everyone had fun watching (the first) Zombieland; making it a more visceral experience can only make it better,” producer Gavin Polone said. “I don’t think you want to see Ordinary People in 3-D. But Zombieland is clearly one movie that will benefit from (the technique).” Director Ruben Fleischer has been confirmed for the sequel while discussions are being had with the two main stars.

Bourne Identity: Is the fourth Bourne film in jeopardy? Director Paul Greengrass recently announced that he would not return to the franchise despite his work on the two previous entries. His departure was reportedly due to disagreements with Universal on the George Nolfi-penned script. If a resolution is not reached, the studio will lose its star as well. “I’m waiting for Paul,” Damon told the Hollywood Reporter. “And he’ll come back when there’s a script.”

Underworld: Prepare to go further into the Underworld with a fourth chapter in the franchise. The film, which has no director or actors assigned to it yet, will be penned by John Hlavin (The Shield). “It will satisfy old fans and excite new audiences, meaning that we don’t want to redo the first three movies, so steps are being taken to honor what fans have loved but at the same time introduce fresh elements,” Hlavin teased.

Jackass: Are you ready to watch more cringe-worthy stunts? Do you think you could handle seeing them in 3D? Starting January 25, filming on Jackass 3 will begin with Johnny Knoxville front and center once again. The Paramount feature, which will also debut in 2010, will be helmed by Jeff Tremaine, the director behind the earlier installments.
