We haven't heard much on the Untitled G.I. Joe Sequel since we reported back in January that Zombieland writers Rhett Reese and Paul Wernick had signed on to write the script. MTV Movies Blog recently spoke with G.I. Joe: The Rise of Cobra producer Lorenzo di Bonaventura, who revealed that the plan is to start shooting in the spring of 2011 for a summer 2012 release. Here's a portion of the site's interview with the producer.

Lorenzo di Bonaventura: We're not that far. I think it'll be pretty soon. It'll need a lot of work. They all do. I've had an occasion to read some of their pages, so I know the quality is there and the sense of tone is there. Paramount is very excited about us getting it going. No dates have been set. In our heads we think 2012 - that summer.

MTV: So then you'd start shooting when?

di Bonaventura: We'd probably start next spring.

He was also asked whether the main cast of the first film such as Channing Tatum, Joseph Gordon-Levitt and others would return for the sequel, but he would only say, "We haven't defined it yet. We're gonna keep that under wraps for the moment." He also said there haven't been any discussions about shooting the movie in 3D, but he said, "I'd definitely be open to it."

We'll be sure to keep you posted on any further information about Untitled G.I. Joe Sequel as soon as we have more information.
