Will Smith says he's now old enough to play Uncle Phil in a possible re-boot of Fresh Prince; Jamie Oliver talks about 20 years of being on telly, Jenna Coleman reveals some of the stranger Doctor Who fan requests, and Tom Chaplin performs live in the studio.

Enjoying a Christmas cocktail made by Jamie Oliver, Graham and his guests talk about Christmases past and present...

Will Smith says he will be home for Christmas, "It's a big thing in the Smith household." Jenna Coleman reveals, "My brother used to get double the presents I did because he helped write my wish list with stuff he wanted on it and got!" Jamie, recalling a less than successful Christmas, says, "I bought a very cheap Santa outfit and when I came in saying, 'Ho Ho Ho' my kids started crying. When I took the beard off and said, 'It's Daddy' they cried even more!"

Will, talking about starring in Fresh Prince of Bel Air, says, "It was my very first role and I was very, very focused on being successful so I learnt the whole script and everyone else's lines. If you watch the first four or five episodes you can see I'm mouthing other people's lines. It's terrible and I can't bear to watch it."

Asked about his new Netflix series Bright, which he describes as "Training Day meets Lord of the Rings', he says "It's really a fun and bizarre action movie. It takes some time to get your head around. Joel Edgerton plays an Orc and had to spend four hours a day in makeup and I'd just turn up ready to go - it made him cross," adding jokingly, "I felt bad taking most of the money!"

Talking more about working with Netflix, he says, "It's a relief not having to rely on just one opening weekend at the box office to see if your film is a hit or not."

Asked about the possibility of a rumoured Fresh Prince re-boot, he says, "Man, I'd have to be Uncle Phil in that one now I'm nearly 50!"

On meeting Muhummad Ali before playing him in the film Ali, he recalls, "I was terrified when I met with him - he was the most recognisable person on earth. He looked me up and down and said, 'Man, you're almost pretty enough to play me!'"

And, on Barack Obama's request that Will be cast as him in an upcoming biopic, Will says, "We were talking about it and he said, 'Well, you certainly have the ears for it!'"

Jamie, talking about being plucked from obscurity to become a TV chef, recalls, "I never wanted to be on telly and the first show was terrible. Really bad. It was an interesting lesson in mistakes and failure because we had to go back and re-budget and that's when I started having a conversation off camera, used my own music, and became a bit more documentary about it. So, if it wasn't for that massively terrible first show - which you have never and will never see - I wouldn't have the style of show I have now."

And, on the success of his latest cook book, Quick and Easy Food, he says, "It's the fastest selling book I've ever done, which means it's resonating with people of all ages. Writing a book is an emotional thing for me so after 20 years it's a bit of a relief that it's still going well."

Jenna, talking about appearing in various Christmas specials over the years, including this year's Victoria, and asked if her family stop the festivities to watch her, she says, "I think they thought that this year there was going to be a break and then Victoria was announced. We normally go 50/50 - there is the drunk games room and my grandparents watching the telly. My grandma will always watch me unless something like Wimbledon is on and then I get 'sky+'d'"

Talking about the legacy of being in Doctor Who, she says, "I'll be sitting next to someone and they started humming the theme tune. Most people just ask me, 'Where's the Doctor?' But the weirdest thing I have been asked to do is sign someone's underpants. I politely declined!"

Tom Chaplin performs Midnight Mass live in the studio, before joining Graham for a chat about his new Christmas album.
