Fresh from his farewell to the High School Musical franchise, Zac Efron visits the studio to discuss his new film 17 Again, a Big-style comedy in which he stars alongside Matthew Perry. Also on the sofa this week is Little Britain star David Walliams. Music is provided by Pet Shop Boys.

Graham is joined by Hollywood hell-raiser Johnny Knoxville to talk about Jackass 3D; veteran comedienne Joan Rivers, who talks about having a year of her life documented in the award-winning Joan Rivers: a Piece of Work; and everyone's favourite 'Nan', actress Catherine Tate. Plus the Pet Shop Boys chat and perform one of their greatest hits.

Graham is joined on his heroic sofa by Oscar winner Ben Affleck, starring as Batman in Batman v Superman: Dawn of Justice, his adversary Superman, British star Henry Cavill, and five-times-Oscar-nominated Amy Adams, who plays Superman's squeeze Lois Lane.

With music from The Pet Shop Boys, performing their new single The Pop Kids.
