Titillating talk-show host and Telegraph columnist Graham Norton has an all-male line-up tonight. He's joined by British actor Damian Lewis, who's currently garnering rave reviews for his role in Channel 4's US spy drama Homeland. Lewis's fellow Etonian Dominic West - who starred in the searing US crime saga The Wire - drops by to talk about his latest film John Carter, about an American Civil War veteran mysteriously transported to Mars. Also among the guests are French actor Gérard Depardieu and singer Olly Murs, who performs his new single Oh My Goodness.
