"I never screen-tested," the actor said in an interview with Shortlist after revealing that he was in talks to play Robin. "I had a meeting with Joel Schumacher. It was just one meeting and, no, I didn't end up doing it...As I recall I took the meeting, but didn't want to play the role. Joel Schumacher is a very talented director but I don't think I was ready for anything like that."
DiCaprio was also in talks to play Anakin Skywalker in the recent Star Wars prequels but said that, "he didn't feel ready to take that dive" indicating he wasn't enthusiastic about signing up for a big franchise movie.
Perhaps most surprisingly, the actor also confessed that he had the chance to take the lead role of Peter Parker in Sam Raimi's Spider-Man back in 2002, "That was another one of those situations, similar to Robin, where I didn't feel ready to put on that suit yet. They got in touch with me."
As for whether he'd ever be willing to play a superhero the actor added, "You never know. You never know. They're getting better and better as far as complex characters in these movies. I haven't yet. But no, I don't rule out anything."
