Michael Keaton has revealed that he would play Batman again "in a heartbeat" if Tim Burton was directing the movie.
The 63-year-old actor played the Caped Crusader in the original big screen adaptations, 1989's Batman and 1992's Batman Returns, both with Burton at the helm.
The superhero has gone on to be played by Val Kilmer, George Clooney, Christian Bale in Christopher's Nolan's trilogy and currently Ben Affleck who will appear in Zack Snyder's Batman v Superman.
According to Slash Film, Michael was asked in an interview with Entertainment Weekly magazine if he would ever consider returning to the role.
He said: "If it was Tim Burton directing? In a heartbeat. Tim, in movies, really invented the whole dark superhero thing. He started everything, and some of the guys who have done these movies since then don't say that, and they're wrong."
The article, which is yet to appear online, reportedly reveals that both Keaton and Burton wanted to come back to do a third film "delving into Batman's past", but studio Warner Bros didn't want that.
Michael said: "I hadn't been stupid about it. I always knew it was a big machine with a big studio and corporation and board behind it. But the simple answer was, it wasn't any good.
"I was nice. I said to them, 'This is a really interesting character with a dual personality.' I tried to make them understand. But when someone says to you, 'Does it have to be so dark?'... I thought, 'Are we talking about the same character?' So finally I just said no. And as the years wore on, I think more and more people said, 'Yeah, I get what that dude was about'."
In his new film Birdman, due out in January, Michael parodies the film industry as a washed-up actor who once played an iconic superhero trying to reboot his career on Broadway.
