A day ahead of Doctor Who's return to our screens, the actor will be talking about the latest series as well as his decision to leave the show after three years in the role:
"It's bye bye. Doctor Who is a great job but it is TV factory with so many episodes and I would worry that I wouldn't do my best work with the same vigour and fun.Other guests on tonight's show include Miranda Hart, who will be discussing her role as Miss Hannigan in the new West End production of Annie, Keeley Hawes on the new series of The Durrells, and Hollywood legend Warren Beatty talking about his new film Rules Don't Apply. Music will be provided by Jennifer Hudson who will be performing her new single 'Remember Me'.
"I've left it while I am still enjoying it. Three years is probably enough because people get wiped out by it."
The Graham Norton Show airs tonight at 10:30pm on BBC One, with viewers in the UK able to catch up afterwards on BBC iPlayer. Viewers in the US will be able to see the episode tomorrow on at 11:20pm (EDT) on BBC America, completing a Peter Capaldi triple bill which also includes the opening episodes of Doctor Who Series 10 and Class Series 1.
Doctor Who returns with Series 10 opener The Pilot tomorrow at 7:20pm on BBC One and at 9/8c on BBC America.
