Who is on BBC's The Graham Norton Show tonight - December 15

Graham Norton's TV sofa has welcomed some huge names from Hollywood over the last few weeks - including the likes of singing superstar and actress Cher, Tom Hanks, Julia Roberts, Julianne Moore and Timothee Chalamet. And this week he'll be chatting to British TV royalty.

Appearing on Friday night's (December 15) BBC One will be Imelda Staunton, Ncuti Gatwa and Northern Irish actor Jamie Dornan. There will also be an interview with Scottish actor Jack Lowden and music from American singer-songwriter Gregory Porter.

Staunton will discuss her role as Queen Elizabeth in the final episodes of The Crown. The veteran actress, 67, has portrayed the former monarch in the fifth and sixth series of the hit Netflix royal drama, following in the footsteps of Claire Foy and Olivia Colman who played younger versions of Queen Elizabeth in the show.

Part two of the final season, which was released on Thursday, sees the Queen reflect on the future of the monarchy as she reaches her Golden Jubilee. It also covers the wedding of Charles and Camilla and William and Kate's romance.

Meanwhile Jamie Dornan will chat through the return of amnesia thriller The Tourist. The first series followed a man waking up in the Australian outback with no memory who has to discover his identity before his past catches up with him. Series two was filmed in Ireland, where the star's character Elliot tries to unlock the secrets of his past.

The headline star on the sofa this week is arguably Doctor Who star Ncuti Gatwa, who will talk about becoming the Fifteenth Doctor ahead of his first full episode airing on BBC One on Christmas Day.
