Leslie Mann and Paul Rudd on Apatow film, This is 40

Producer, writer and director Judd Apatow hired his entire immediate family for his latest film, This is 40.

Leslie Mann, who stars as 40-year old Debbie, says the film was inspired by some elements of her real-life marriage to the director.

Paul Rudd, who became part of the Apatow family for the project, told the BBC's Rachel Curtis about being in the director's familiar cast.
