They'll be rolling out the red carpet tonight as a stellar cast of talent drop by for a chat. Michael Fassbender talks about his role in 12 Years A Slave, Idris Elba reflects on stepping into the shoes of a legend in Mandela: Long Walk To Freedom and there's a chance to get the inside track on punchy comedy drama Girls from US actor/writer Lena Dunham. Completing one of Graham Norton's most diverting line-ups are national treasure Olivia Colman and rockers Keane.

Frank Sidebottom: the true story

Frank Sidebottom was possibly the strangest pop star in history. Jon Ronson, who played in his band, and has co-written a film inspired by the character starring Michael Fassbender, remembers Frank's creator Chris Sievey as being even more eccentric than his papier-mache alter ego.

Steven Toast as James Bond? Why not? He's only got Michael Fassbender and Nigel Havers for competition, after all. This audition, like so many others, sees Matt Berry's titular luvvie misjudging the mood somewhat. But there are even greater problems in store when a poker game with Andrew Lloyd Webber turns nasty. With Webber's universally feared enforcer Michael Ball (played here by Michael Ball) on his tail and a gay porn voiceover to complete, Toast's on his uppers.

Still, there's always some way that things can get worse... This first series comes to an end with lots of blood and finally, a glimpse of Toast's terrible play. By and large, it's been a delight: a tour de force of virtuosic vocal and physical comedy and the kind of relentless, off-the-cuff daftness that can only be the result of meticulous planning and dedication. Encore!

He's made a big impact as a star in such movies as Boogie Nights, The Departed and The Fighter but for some of us, Mark Wahlberg will always be Marky Mark. Chances are, though, that Graham Norton won't have the front to request a pose in shiny white Calvins - Wahlberg is very serious about his acting and is in Britain to talk about latest film Broken City, a crime thriller co-starring Russell Crowe. Now that must have been a punchy set. There's more movie talk with Shame star Michael Fassbender, soon to be seen in a live-action take on gaming sensation Assassin's Creed, plus laughs from Sarah Silverman and music from Laura Mvula.

First photograph of "Frank" film

The first photo from the set of the film Frank. Frank is a comedy about a young wannabe musician, Jon (Domhnall Gleeson), who discovers he's bitten off more than he can chew when he joins a band of eccentric pop musicians led by the mysterious and enigmatic Frank (Michael Fassbender) and his terrifying sidekick Clara (Maggie Gyllenhaal). Frank is based on the memoir by Jon Ronson and is a fictional story loosely inspired by Frank Sidebottom, the persona of cult musician and comedy legend Chris Sievey.
