Judd Apatow is currently in the midst of shooting his "Knocked Up" spinoff, the formerly titled "This Is Forty," and thus far, he's done a pretty good job of keeping the plot details under wraps for now. What we do know is that it will pick up with Pete (Paul Rudd) and Debbie (Leslie Mann) five years after the events of the first film, assembling a cast of mostly new faces like Megan Fox, Albert Brooks, Lena Dunham, Chris O’Dowd, Wyatt Russell, Ryan Lee, Melissa McCarthy and Annie Mumolo with the only returning actor from "Knocked Up" thus far being Charlene Yi, who played the quirky Jodi. However, it looks like Apatow might be trying to keep some more of returning folks a secret, though photogs on the set of the film may have given it away.
New pictures from the set of the film have surfaced over at The Superficial reveal Jason Segel shooting some physical scenes with Mann, in what looks like a reprisal of his character from "Knocked Up." As you might recall, Segel played Jason, a roommate of Seth Rogen's Ben who took a rather creepy interest in Debbie. And while it seems somewhat improbable that he's now a personal trainer -- as revealed by the set photo showing his company ride in the background -- you might recall a throwaway line from the film in which he says he's going "to go make a protein shake." Could Jason have cleaned up his act? Guess we'll see.
His appearance certainly bodes well for the return of other cast members (and makes Yi's appearance a bit more logical) and we'd be surprised if Rogen doesn't appear at all seeing as how famously Ben and Pete hit it off. Of course, none of this is officially official but pictures don't lie. It looks like there are still lots of surprises to come from Apatow and crew, but it's a wait for now. The film is currently slated to hit theaters on December 21, 2012.
