It’s Only a Play’s plethora of stars recently allowed the CBS News Sunday Morning cameras a sneak peak of what they get up to in and around the Schoenfeld Theatre. Check out below, as Oscar winner F. Murray Abraham turns the stage into a workout studio, Tony winner Nathan Lane and newcomer Micah Stock run lines and Harry Potter alum Rupert Grint drops his pants. The cast, which also includes Matthew Broderick, Stockard Channing and Megan Mullally, also revealed to host Lesley Stahl their superstitions and rituals (not to mention where they hang out after the show). The production, directed by Jack O’Brien, will open officially on October 9.
