Paul Rudd and Leslie Mann have been on board with Judd Apatow for a new film for a while. Fortunately, it sounds like they’ll both be starring, and they’ll be tackling their Knocked Up characters again.

According to Apatow, “people really responded to their characters and problems.  I felt like there was a lot of ground I could explore with them.”

That’s absolutely true. Great chemistry and great takes on what married life really means. This means that Apatow is definitely not done exploring his favorite theme, and that it’s unclear whether this film will be heavier on comedy or on heartbreak. It also leaves the question open of whether Katherine Heigl will be back since her character was Mann’s character’s sister. And if Heigl’s back, wouldn’t Seth Rogen be back? And then wouldn’t it be a sequel to Knocked Up essentially? [HitFix]
