Want to feel ancient? It's 50 years since Mary Poppins blew into Cherry Tree Lane in the classic Disney movie based on PL Travers' novel.

Its star Dame Julie Andrews will be Graham's very special guest on tonight's show.

And, if you doubt the film's enormous cultural significance for one second, let me point out that the spellcheck on my computer just recognised the word supercalifragilisticexpialidocious.

Actress Dame Julie also shares a Despicable Me connection with Graham's musical guest Pharrell Williams, who'll be performing his new single Marilyn Monroe.

For the benefit of younger viewers who've never found themselves humming Chim, Chim Cher-ee in an idle moment, Channing Tatum and Jonah Hill will be on the show, too, to chat about their new movie.

The sequel to 21 Jump Street sees them going undercover as high school students once again.

Yes, it's called 22 Jump Street...

Radio Times review

Amazingly, it's 50 years since Mary Poppins wafted in to number 17 Cherry Tree Lane for the Disney version of PL Travers's novel. So, although guest Julie Andrews isn't likely to arrive clutching a carpet bag and a parrot-headed brolly, she'll probably chat a little about one of her best-loved film roles.

Perching next to her on the Norton sofa are Channing Tatum and Jonah Hill, stars of action comedy film 22 Jump Street. And, no doubt making everybody "Happy" and wearing an oversized hat, is Pharrell Williams who performs Marilyn Monroe.

Alan Carr interview

At the TTG Travel Awards 2013, the comic revealed that he didn't like cruises but would like to travel with Gok Wan, Channing Tatum and Bradley Cooper.

Camp frolics on the couch are guaranteed as our host is joined by David Walliams for a triple-entendre gossip about sitcoms, Simon Cowell and whatever else crops up amid a bout of giddy tomfoolery. Keeping it a touch more real, Jamie Foxx and Channing Tatum will try to keep Carr focused on their new movie, White House Down, while music comes from Mutya Keisha Siobhan, once the original Sugababes. Who knows why their names aren't alphabetical - it's bound to cause trouble...
