While doing the press rounds for Need for Speed, Michael Keaton opened up more about his time working with director Tim Burton on 1988's Beetlejuice and 1989's Batman. As he's said in the past, he does want to return for Beetlejuice 2. But only under the right conditions, and if Tim Burton returns to helm this long gestating follow-up. Now, he claims its the only sequel he's ever wanted to do, despite having donned the bat cowl a second time in 1992's Batman Returns.

"I've been talking about it for years and I've been saying if I ever did anything again, it'd be that. I want to do that. The rumors, they've risen before and fallen away. Now, if Tim is involved, and I think he might be involved, I'd be more than interested. I mean, he's so original, and he's an artist. It's unique. There's nothing like it. You can't compare it to anything. It has to be done right."

Last month, the actor revealed he had been discussing the sequel with Tim Burton and writer Seth Grahame-Smith, but that nothing is set in stone just yet.

Michael Keaton then chimed in about Ben Affleck taking over the role of Bruce Wayne in Batman Vs. Superman. Ever since the actor landed the role in Warner Bros.' highly-anticipated Man of Steel sequel back in August, fans have been voicing their displeasure over this casting. Michael Keaton revealed in his interview with the Today show that he thinks Affleck will be great as the iconic crime fighter. He also doesn't understand all of the negative backlash surrounding his casting.

"He's going to be great. I don't follow it much, but I guess there was some sort of ... I don't know why people get excited about things. Frankly, I don't understand it."

The actor added that he was under similar pressure when he first signed on for director Tim Burton's 1989 movie Batman, hinting that the producers were nervous about how the fans would respond to their version of the iconic character.
