Los Angeles, Oct 16 (IANS) Actor Michael Keaton says he would reprise his role as Batman if he could work with Tim Burton again.The 63-year-old actor played "The Caped Crusader" in 1989 movie "Batman" and the 1992 sequel "Batman Returns". He says he would be prepared to create a new cinematic story if Burton wanted to, reports contactmusic.com. When asked by Entertainment Weekly if he would don the Batsuit again, he said: "If it was Tim Burton directing? In a heartbeat!" Keaton also praised Burton, 56, for being the first director to create "dark" superhero films -- something which directors like Christopher Nolan, who helmed "The Dark Knight" trilogy with Christian Bale as Batman -- have been lauded for. "Tim, in the 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," he said. Keaton decided to exit the 'Batcave' after the second film, handing the famous cape over to Val Kilmer for "Batman Forever", despite being offered $15 million to star in a third film. Explaining his decision to walk away from the franchise, he said: "It sucked. Yeah, it was just awful."
