Rudd Mann Return For Knocked Up SpinOff January 7, 2011 Knocked Up Spawns Paul Rudd-Leslie Mann Spinoff Variety are reporting that Judd Apatow’s next project will feature Leslie Mann and Paul Rudd reprising their roles from ‘Knocked Up.’ But word is the movie won’t be a straight spinoff or a sequel. Think Get Him To The Greek and Forgetting Sarah Marshall. The untitled comedy, which is set to be released Summer 2012, will see Apatow write and direct the film, the first he has directed since 2009’s ‘Funny People.’ Apatow will also produce along with Barry Mendel and Clayton Townsend. In 2007’s ‘Knocked Up,’ Mann played Katherine Heigl’s older sister, who is married to Rudd’s character. At the moment plot details are being kept under wraps, and it’s not clear whether Katherine Heigl or Seth Rogen would reprise their roles from ‘Knocked Up,’ one of Apatow’s biggest successes at €153 million worldwide.
