James Bond star Daniel Craig has said he "loves" working on the franchise despite earlier saying he would "rather slash my wrists" than make a fifth movie.
The 47-year-old actor has reprised his role as the MI6 agent for the fourth time in the latest 007 adventure Spectre.
Asked about returning to Bond, Craig joked: "Do I have a choice?"
He added: " I love making these films and the chance to come and make a movie after Skyfall was a huge challenge.
"That was a huge success but that was a great thing to have at your back.
"You just want to move on and make a bigger and better version of the movie.
"We've spent a huge amount of time on this movie just trying to find the humour in it, but also that the story is as strong and as real as possible."
Skyfall, released in 2 012, became the highest-grossing Bond film in history.
It also won two Oscars for its score including Adele's theme tune and Bafta awards for Outstanding British Film and Best Original Music.
Craig - who joined his co-stars including Ben Whishaw, Naomie Harris, Christoph Waltz, Andrew Scott, Monica Bellucci, Lea Seydoux and director Sam Mendes for a photocall in London - does many of his own stunts in the 24th instalment of the action series, which included intense chase scenes with former professional mixed martial artist and professional wrestler Dave Bautista.
"He moves so quickly and is so agile and for me, I think the sequences with him are all the more terrifying because of his presence," Craig said.
"You just want to make the stunts as real and fresh as possible.
"We try to do stuff that we don't think people have seen before, but having someone like Dave Bautista who spent most of his career being thrown around and throwing other people around, he really knows what he's doing and he's incredibly safe."
Craig admitted he accidentally injured Bautista - who joins the pantheon of Bond villains as Mr Hinx, a henchman for the criminal organisation SPECTRE - during some of their sequences together.
He said: " Believe me, I was in the other room when I realised I'd done it.
"I thought he'd come after me but he was so sweet about it.
"He said, 'Look, it's happened before. Don't worry about it'."
Craig, who made his debut as Bond in 2006's Casino Royale, also revealed he has no regrets about taking the role - even if it meant losing some much-valued privacy.
"No, not for a minute," he said.
"I was aware of that (the loss of privacy) going in and I've remained as private as I possibly can.
"That, for me, is the most important thing but I've also managed to make the movies, which are also incredibly important to me."
Spectre opens in UK cinemas on Monday.
