Today a red-band (R-rated) trailer for Judd Apatow’s This is 40 made its debut, and you’ll definitely want to catch this one to see some of the film’s raunchier moments.

Within you’ll see just-revealed scenes involving Paul Rodd and Leslie Mann at home doing things the kids definitely don’t want to walk in on.

This is 40 is a “sort of” sequel to Knocked Up and has so far been warmly received by critics yet knocked down a few pegs for its length. Other cast members include Jason Segel, Chris O’Dowd, Megan Fox, Albert Brooks, John Lithgow, Lena Dunham, and Melissa McCarthy.

Writer/director/producer Judd Apatow (The 40-Year-Old Virgin, Funny People) brings audiences an original comedy that expands upon the story of Pete (Paul Rudd) and Debbie (Leslie Mann) from the blockbuster hit Knocked Up as we see first-hand how they are dealing with their current state of life.

Set for a release on Dec. 21, This is 40 is currently sitting at 81% on Rotten Tomatoes. We’ll be sure to have a review up come the film’s release date, but in the meantime, are you excited to see the film?
