Fans of Paul Rudd are eagerly awaiting the December 21 big-screen release of This Is 40, his latest comic collaboration with writer/director Judd Apatow and Apatow’s real-life wife, Leslie Mann. A spinoff of the 2007 hit Knocked Up, This Is 40 features Rudd and Mann as battling couple Pete and Debbie, with Mann’s daughters Maude and Iris Apatow as their children. On November 11, Apatow and Mann headed to Broadway’s Cort Theatre to see Rudd’s star turn in Craig Wright’s black comedy Grace. Also on hand to congratulate the Broadway headliner was monologist and theater vet Mike Birbiglia (Sleepwalk With Me).
