Apatow is currently in the midst of shooting a comedy-drama tentatively titled This Is Forty. Since it is a spin-off of 2007's Knocked Up, following Paul Rudd and Leslie Mann as married couple Pete and Debbie, it made sense to wonder if Rogen and Katherine Heigl would reprise their roles as Ben Stone and Alison Scott, if only for a brief cameo.
While promoting the upcoming dramedy 50/50, which he produced with writing partner Evan Goldberg and stars in alongside Joseph Gordon-Levitt, Rogen confirmed to Movies.com that he won't be showing up in This Is Forty. "Yeah I'm not in it, but I went to visit the set and it looked hilarious," he said. "It was a good choice, honestly, because I think it would've confused people, but I'm really looking forward to seeing it; I thought the script was unbelievably funny."
Interestingly, the film's cast does include Jason Segel and Charlene Yi, both of whom appeared in Knocked Up. Segel's lothario character was attracted to Debbie, while Yi had no scenes with either Rudd or Mann. So this begs the question: Will Segel and Yi be playing the same roles, or are they appearing as entirely new characters? Keep in mind that in the Forgetting Sarah Marshall spin-off Get Him to the Greek, which Apatow also produced, Jonah Hill starred as a character completely different from the one he established in the first film.
Around the time of Knocked Up's release, Rogen and fellow Canadian/Undeclared veteran Jay Baruchel appeared in a trailer for a fictitious comedy titled Jay and Seth vs. The Apocalypse, featuring the two bickering in a postapocalyptic hovel. Shortly thereafter, it was announced that the trailer would be expanded into a feature film. Gradually, though, it began to seem like one of those projects that simply disappeared and would never actually happen.
Not did Rogen confirm that he and co-writer Goldberg will be making their feature directorial debut on the film, but that production is set to begin in February 2012. He said that the scope of the "oddly personal" film has now expanded. "It's now much more than just Jay and Seth," he explained. "There's many other people vs. the apocalypse now. It's gonna be crazy."
Here's the Jay and Seth vs. The Apocalypse trailer to refresh your memory:
