The Graham Norton Show

Benedict Cumberbatch hints at the last outing of Doctor Strange, Maxine Peake talks about stand-up, Matt LeBlanc says the theatre is not for him, Mary Berry reveals a darker side, Claudia Winkleman says appearing with Mary is all that mattered, and Calvin Harris and Dua Lipa perform live in the studio.

Benedict Cumberbatch, talking about Avengers: Infinity War, and asked what happens in the new film, says, "I was allowed to read the whole script so I do know what is happening, but I can't tell you about it. What I can say is that I am helping the world and worlds beyond it - potentially."

Asked if it will be the end of Doctor Strange and possibly some of the other superheroes, he shrugs and says, "Let that rumour take flight." Adding, "This film is so shrouded in secrecy."

Revealing how he felt when he first put on his full costume, he says, "There was a moment. I remember when I put on the whole thing and looked in the mirror and just started laughing like a 12-year-old. It was my superhero moment!"

Maxine Peake, talking about the strain of performing Hamlet, says, "When I was in it with Christopher Eccleston. I thought he was really boring. After the show, he would never come into the bar. He'd have a glass of water and have to go home and I thought, 'What's wrong with him?' and then I played Hamlet and realised. I didn't even manage a glass of water!"

Talking about her new film Funny Cow, in which she plays a Northern 70's stand-up comedian, she says, "It's very dark and very much of the era. We've not sweetened it at all. We'll never learn if we don't look back to that time. The jokes are authentic but uncomfortable. Some of the material made my top lip sweat."

Asked whether she did any comedy performances to prepare of the role, Maxine says, "I am not at all 'method' and when the director said I should do some open mics in comedy clubs I said, absolutely not. I can do Hamlet but under no circumstances could I do stand-up."

Matt LeBlanc, asked if he now lives in the UK, after working on Episodes and Top Gear, says, "It's half and half. I have a flat here with my girlfriend but my home is in LA." Adding jokingly, "I spend a lot of time here so I have to kind of like it!"

Asked if he would ever consider performing on stage, he says, "Nope. Never been in one. Never want to be in one. It's too steep a hill for me. I like sitcoms - you do one performance and that is it. You learn your lines, you perform and then you delete."

Asked about being recognised as Joey from Friends everywhere he goes, Matt says, "We were filming Top Gear in the Atlas Mountains in the middle of nowhere and this guy came out from a cave and said, "Hey, how are you doin?'"

Mary Berry and Claudia Winkeman join Graham to talk about their new BBC One series Britain's Best Home Cook.

Claudia, talking about getting involved with the series, says, "I didn't ask anything about it once I knew Mary was on board. I just wanted to be with her!"

Talking more about working together, Claudia says, "We were sitting chatting one day when Mary revealed a much darker side." Mary, taking up the story, says "I was arrested 25 years ago. I was going to the US to do some cookery demonstrations and was worried that there might be problems so I weighed out all the ingredients - flour, sugar - and put them all in little plastic bags. When I arrived at the airport the sniffer dogs made a bee-line for me. Suddenly I was surrounded by uniformed people and my assistant and I were put in separate cells. It was alarming. When I was asked if was going to make money from the stuff, I said, "I do and my fee has already been agreed."

Calvin Harris and Dua Lipa perform the TV world exclusive of One Kiss live in the studio, before joining Graham for a chat about performing together and their new track becoming the UK's number one single.
