In an interview with Movieline Zac Efron talked about how he hasn’t singed on for any action movies yet, saying that he has to find the right one:

“When a superhero movie is about to get made, we’re at different levels of conversation about it. I find that it’s hard to commit to an action movie for the sake of doing action. I love action as much as the next guy, but I wouldn’t say it’s my favorite genre or one that I look for an amazing performance in… I think it would be about finding the right one.”

So when will we get to see Zac acting in an action flick?

“It hasn’t been the right time necessarily, or it’s too early. I don’t feel that I’ve earned it quite yet, to be honest. The people that you see them find for superheroes, you go, ‘Oh yeah, that’s great. That guy is perfect, what a great idea.’ Ryan Reynolds as Green Lantern? You go, ‘Finally, he’s going to do something great! We’ve been waiting for it, he’s done all these other things and now I want to see him as that character.’” [Source]
