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.
