Miriam Margolyes says she loves Call The Midwife, Daniel Radcliffe says he was mistaken for a homeless person, Alan Cumming talks about the downside of being a superhero, Sharon Horgan sheds light on Catastrophe's dark ending and Craig David performs live in the studio.

Miriam Margolyes, talking about her role in Call The Midwife, says: "I am the only Jewish girl in the convent, and I love it!" After seeing a clip of the show, she adds, "I've never seen that before. I never watch myself and now I know why. There's a lot of overacting!"

Revealing that not everything goes to plan in the theatre, she says, "I was playing a drunk prostitute and had to sit down in a chair. Unbeknownst to me, sometime between dress rehearsal and the performance castors had been attached to the chair. I sat down and was thinking to myself, 'I am good, I feel like I'm moving.' Well, it was a raked stage and very slowly and imperceptibly I careened downstage and tipped into the audience followed by the chair. I don't know how it all ended, but the poor man I landed on was desperate to get out from under me!"

Daniel Radcliffe, talking about his new play Endgame, in which he stars with Alan Cumming, and asked if his love of theatre is to prove his mettle as an actor, says, "I think it makes me better. It's hard work and gives me a lot of confidence to know that I'm not entirely the product of editors and producers and that I can do it on my own and exist outside of that. It's also fun. I love being on film sets, but you don't get the raw rush you get on stage."

Asked if his fans will go and see whatever he is in, he says, "I think there is a fair amount of that. It's a nice part of my job that I maybe get to introduce people to stuff they might not otherwise see."

Talking about being recognised wherever he goes, he says, "It's weird and funny, with some very odd moments. I was in New York recently with my girlfriend and while she was in a shop, I was outside with our adopted dog. It was very cold, and I had on a hoodie, a fleece and then a big coat over the top. Because it was so cold, I knelt down to warm the dog and I saw this guy looking at me and then he walked past me. But then he came back and handed me five dollars and said, 'Get yourself a coffee mate.' Apparently, I need to shave more often!"

Alan, talking about his experience of being part of a major movie franchise when he played Nightcrawler in X-Men, says, "Since I did a fan event, I've said I will never do another one. I did one called Collectomania and the emphasis was on 'mania'. They paid me lots of money and flew me in, and then guess where it was? A shopping mall in Milton Keynes! There were lots of people and everyone was very nice, but you had to wait to get paid in cash - it was mortifying. I didn't like it at all, and I felt a bit like a whore! When I got back to the hotel, I put all the money all over my chest and made my husband take a photo so I wouldn't forget what a whore I am!"

Sharon Horgan, talking about Catastrophe, and asked if both characters die at the end of the final episode, says, "No. I mean, maybe. It was supposed to be ambiguous. You could take it as that. Rob [Delaney] always thought there was a slightly dark ending possibility, but I always thought they made it back to shore. They'd had a fright, but they made it back. It's supposed to be both and to give you hope as well as fear for their future."

Talking about her new film Military Wives and asked what it was like working with Kristin Scott Thomas by Miriam, Sharon says, "She's brilliant and super funny. She is lovely and great crack."

Craig David performs Born To Do It live in the studio, before joining Graham for a chat about the album and his upcoming tour.
