The Graham Norton Show

Chris Hemsworth says he doesn't know what happens to Thor, Paul Rudd jokes about his physique, Juliannne Moore says you can be messed up dating at any age, Kit Harington says he had to reveal the plot of Game of Thrones and Tom Walker performs live in the studio.

Chris Hemsworth, talking about his new movie Avengers: Endgame, and asked how the film begins, says, "This has been the hardest press tour, because we really can't say anything."

Talking about the film being the last in his contract, and asked if that means things don't end well for Thor, he says, "I can't tell you. But, regardless of what happens in this film with any of these characters, it's just the end of phase three for Marvel. So, who knows?"

Asked how he felt when the filming ended, Chris says, "We all wrapped at different times and people disappeared off to other things so the press tour has had a bitter sweet nostalgic feeling. It's a bit like finishing high school and saying, 'See you next summer maybe'. We were all reminiscing and saying what an incredible journey we had all been on together."

Talking about keeping the storyline secret, he says, "I am good at forgetting stuff, which helps." Paul Rudd adds, "We haven't seen the film and there are many things that we don't know because we didn't read the whole script."

Paul, joking about his and Chris's physiques, says, "I'd been working out really hard, I'd been eating really great for years and years, and then, when we were filming I stood behind Chris just after we'd got out of our [super hero] suits and I thought, 'What is the point?" We're basically comprised of similar materials but there is this [pointing at Chris's body] and then there's Ant-Man!"

Asked why Ant-Man wasn't in the previous Avengers film, Paul says, "That's a question I have asked myself. I felt like there was a great party going on and I didn't get an invite."

Juliannne Moore, talking about her new film Gloria Bell, which she describes as, "Celebrating an ordinary woman living a regular life who takes up dancing and falls in love," says, "What the film reveals is that dating never gets easier. You can be as messed up in your 50s as you were in your 20s."

Asked about dancing for the role, she says, "It is so awkward - in real life as well as in front of a camera. It is strange to do it in a movie because you often don't have music during the take so it's hard to do and always challenging."

Kit Harington, talking about Game of Thrones, following eight years of starring in the show, says, "The intensity of finishing something like this and not being able to tell anybody is so hard. It got too much, so I've told one person - my friend James, who doesn't watch the show and fell asleep in the first episode of the very first season. I knew then that he was zero interested in what I do. We were having a drink the other night and I told him everything about how the series ends, and he couldn't have looked less interested if he tried!"

Asked about what does happen in the final season, he says, "They have really upped the budget and gone to town - it is really exciting. There are some incredible sequences, but I've woken up in the middle of the night recently thinking, 'What if, after eight seasons, we've have mucked it up!"

Revealing that just one episode took 55-night shoots in a row to make, Kit says, "I'm not sure I should tell you about it, but it was so intense we were all on the edge of killing each other."

Talking about life after the long-running show, he says, "I was determined to be cool about the end and decided that when people came up to me and said, 'Are you Jon Snow?' that I would say very calmly, 'I used to be.' When I left the set for the final time I was very emotional, and when a girl came up to me and asked the inevitable question, I broke down and cried, 'I used to be!' She backed off pretty quickly!"

Asked about the statue he has of Jon Snow, he says, "I think it will be a water feature or used as a scarecrow on the vegetable patch."

Tom Walker performs Just You and I live in the studio, before joining Graham for a chat about his album and upcoming tour. Asked about his Brit Breakthrough Act award, he says, "It is really very heavy and took four weeks to arrive - on the night they gave me one to be photographed with and then they took it away - I thought they might have changed their minds!"
