The Graham Norton Show

Niall Horan hints at a One Direction reunion in the foreseeable future. Amy Adams says she's not going to let anyone else play Giselle in Disenchanted. Jeremy Renner says he's popular with young fans now he is a superhero. Chris O'Dowd talks about getting in to difficulties on the latest JJ Abrams sci-fi movie.

Niall Horan, talking about what he has been up for the last year, says: "I went backpacking around the world with my two cousins. I wanted to do it properly so we did it on a budget. All of my friends got to do it when I was travelling the world in a different way so I thought it is only fair that I get to do it too." Asked if he thought it had annoyed his cousins to do it on a budget when he is a multimillionaire, he says, "Probably they were but they would never say it to me!"

Talking about the rest of One Direction, and asked if he has started to miss them, he says, "Of course I do. We were all writing and recording, but recently I have begun to think, 'This is it now. I am writing an album for me and I am probably going to tour it on my own.'"

Revealing This Town was partly inspired by his hometown, Niall says, "It's sort of about Mullingar but it has a double meaning. Everything comes back to home, but there is the female aspect too." Asked who the girl is, he says, "Everyone wants to know but it's not about anyone in particular. I've cleared that up on national television now!"

Talking more the new single, and asked if he'd told the other guys in the band that he was doing it, he says, "Yes, of course. They knew I was writing. Originally I wasn't writing for anything for me but when I got back from Asia I just started doing acoustic stuff - the stuff I grew up on - and thought, 'maybe I should release them, they're actually not that bad.'" Adding, "I am 100% relieved that people like it. I have been sitting on it for so long and keeping it a secret. It was a nerve-wracking time. It's always been a daunting prospect but the reaction has been insane."

Asked if he causes a sensation when he goes home to Ireland, he says, "I go a couple of times a year and my dad still lives there so it gets a bit hectic outside the house. I remember Robbie Williams once said to me that his mother closed the curtains in '92 and never opened them again. I get it!"

Answering the burning question 'Will One Direction get back together?'", Niall says: "For now we are doing our own thing. We can't put a date on it but it won't be in fifty years time. It's in the foreseeable future. We've talked about it but for now we'll just play by ear and see what happens."

Amy Adams, talking about the sequel to the cult Disney film, Enchanted, says, "It is definitely happening. They've got a director and they are developing a script. I'm hoping I am in it. I'm not going to let anyone else play Giselle!"

Asked if her six year-old daughter will be impressed that she is going back to be Giselle, she says, "No, she is so cool. I am mama to her and she doesn't think of me as an actress at all. She makes fun of me for it. When I facetime her she says, "Oh my god, it's Amy Adams!'"

Jeremy Renner, talking about his youngest fans, says: "My resting face used to frighten children, but know I am a superhero in Avengers they seem to like me. My resting face is scary but it has made my career!"

Talking about Arrival, in which he stars with Amy, he says, "The science element was complicated. I tried to wrap my head around it and got an idea of what we were talking about but it's not the most interesting thing so I tried to create some emotional content to make binary sound less boring!"

Chris O'Dowd, talking about being in the upcoming JJ Abrams sci-fi movie God Particle, says "I struggled at times because I found the suspension of disbelief difficult. We are trying to save the world and there are moments of great tension and you get to the end of the scene and the written dialogue and there might be an improvisation and normally I am really comfortable in those situations but I would be like, 'Space... what's it all about?' I just couldn't get into believing I was in space, which, when you are doing a space movie, is tricky!"

Revealing an embarrassing star struck moment, Chris says, "When I worked with Philip Seymour Hoffman I was very nervous to meet him because he was my hero. Everyone had told me he liked to be called Phil so I completely over compensated with confidence and when he arrived on set I went over to say hi and said, 'Hi, I am Phil.' He said, 'Oh, I am Phil.' I then said, 'Cool' and walked away."

In a world exclusive, Niall performs his debut single This Town live in the studio.
