Writer and director Judd Apatow is just about to release his Knocked Up spin-off movie This Is 40 in UK cinemas, but he already has plans for a sequel.

This Is 40 focuses on the dysfunctional married life of Pete and Debbie, two supporting characters  from Apatow’s hit pregnancy comedy Knocked Up played by Paul Rudd and Leslie Mann. Apatow’s real life daughters Maude and Iris play the bickering couples troublesome children and he’s apparently enthusiastic to explore their characters even further in another film. As he explained in a recent interview with Getty Images:

“I like that series Truffaut made where he visited the same character five different times in five different movies, and I think it’s fun to see people grow up. So I’m interested in it with Leslie and Paul, but even more so with Maude and Iris. I think it’s fun that we met Maude when she was eight years old, and she didn’t understand where babies came from, and then we see her five years later, and she’s just cursing and screaming and having teenager problems. And maybe in the next one she’s in college, so, you know.”
