A new red band featurette has dropped for the movie, which explains the "Knocked Up" spinoff/sidequel conceit of the picture. Starting off with clips from the aforementioned film, the featurette explains the transition into this movie, and how essentially, Apatow is using the characters of Pete and Debbie -- reprised here by Paul Rudd and Leslie Mann -- to delve into the issues of being in a relationship, turning forty, and handling the challenges that come along with it. Throughout, there is a lot of new footage from the film perhaps most eye-opening off all, Mann handling and being in awe of Megan Fox's breasts.
"This Is 40" opens on December 21st. Watch below and for the bonus round, we've included Fox's ad for Acer computers as well.
