The Graham Norton Show

Shimmying into Graham's studio tonight is Hayden Panettiere, one-time self-mending heroine of cult US sci-fi drama Heroes, now strutting her diamanté chic in slick US country soap Nashville. Also dropping in for a chat is Dan Stevens, Downton Abbey's Matthew Crawley - one of the few decent chaps in the period drama - who was controversially bumped off on Christmas Day. Just after he'd become a new dad, too. Such a harsh way to write out a character. The nation was not amused as we choked on our figgy pudding.

Jenny from the block - J-Lo to her mates (Jennifer Lopez to you and me) - parks her famous rear on Graham's celebrity seat to big-up Beyoncé's Chime For Change charity concert tomorrow at Twickenham Stadium, part of a campaign to empower girls and women alike. Also on hand is TV quiz show fixture, Peep Show actor and comedian David Mitchell, who'll be contemplating his next career move as the current run of daily news satire 10 O'Clock Live nears the end of its run.

Graham's sofa is groaning with an abundance of stellar talent tonight. Michael Douglas will be twinkling with enthusiasm after picking up the best reviews of his career for his turn as as Liberace in biopic Behind The Candelabra and father-and-son co-stars Will and Jaden Smith plug new film After Earth. Guests also include Bradley Cooper and Heather Graham who continue the full-frontal promo assault of The Hangover Part III - you can catch more of the film's cast getting acquainted with Alan Carr over on C4 at 10pm.

The best guests sit on Norton's sofa and tonight's line-up is all Hollywood glitter. Big, smiley Bradley Cooper is a Norton regular who's always great fun - who can forget him flirting outrageously with Jo Brand? He's with Heather Graham to promote another of his Hangover films.

Will Smith did the unimaginable and eclipsed Sir Tom Jones last time he appeared when he did the Fresh Prince of Bel-Air rap with Gary Barlow. Tonight he's with son Jaden (the pair star together in After Earth), while Michael Douglas will be talking about his latest role as Liberace.

Sarah Millican: I'm normal, they're A-list

"I'm weirdly more comfortable in front of a studio audience and telly cameras than at any dinner party. There are fewer forks"

Graham Norton: The go-to guy for anything

He is a sarcastic, breezily insulting and camply subversive gay Irish pixie who has become the most ubiquitous presenter on TV. How has he managed it?

With a career ranging from Peep Show to Broadchurch, Olivia Colman is a national treasure-in-waiting. She's on Norton's sofa for a well-earned break before duplicating herself for a double appearance at 8pm on Sunday - popping on a bonnet in The Suspicions Of Mr Whicher and glamming up for the Baftas, hosted by Norton himself, to see if she's won a gong for comedy and/or drama (BBC1). Alongside Colman tonight are Lord 'The Apprentice' Sugar, Hugh 'House' Laurie and Dwayne 'The Rock' Johnson.

Graham Norton: the making of a national treasure

The BBC's greatest asset is preparing to host the TV Baftas and present next week's Eurovision, but it has not been an easy journey to stardom.

Graham Norton: I don't judge Mark Wahlberg

Graham Norton has said all is forgiven after Mark Wahlberg appeared on his chat show, apparently having had a few too many.

Beaming into Graham Norton's starry ship tonight, Sherlock's Benedict Cumberbatch talks about venturing over to the dark side for a warp-factor adventure in Star Trek Into Darkness. Also in for a chat is Cumberbatch's co-star Chris Pine, who's stepping into the shoes of the legendary Captain James T Kirk. While Sex And The City's Kim Cattrall goes along for the ride, Bonnie Tyler tries to totally eclipse the lot of them with her rendition of Believe In Me, the UK's entry for Eurovision 2013.
