While Benedict Cumberbatch still hasn't been officially confirmed to play Marvel's Doctor Strange, the actor entered final negotiations for the role last month. Before those negotiations took place, the studio was in talks with Joaquin Phoenix for quite some time. Phoenix officially passed on playing the Sorcerer Supreme in October. During a wide-ranging interview with Playboy, the actor briefly touched upon being in contention for this coveted Marvel role..

"I can't talk about it. I've met on all sorts of movies throughout the years. What seems appealing about some of them is the idea of pushing myself in a way that's out of my comfort zone. But really, it's what I'm always looking for-good characters, big ideas and a passionate filmmaker. If those things line up with any kind of movie, I have interest in it."

When asked if he ever regretted turning down a big role, perhaps in a Marvel movie, the actor had this to say, hinting that it may have been a superhero movie.

"There's only one movie I regret saying no to - except the person who ended up doing it was so good and was absolutely meant to do it, so I don't have any regrets. I'm not going to say which one, but it was a really big hit. It's getting to the point where they're making some pretty decent movies. I thought Iron Man was fantastic."

He also chimed in on what his favorite comic books were during his childhood.

"There's some great Batman stuff and classic Frank Miller Dark Knight stuff and Arkham Asylum. But I was always a big Wolverine guy. I love Wolverine - big fucking great dramatic character. They're all conflicted, and they're really interesting."

While we'll have to wait and see how Doctor Strange turns out, under the direction of Scott Derrickson, it's possible this Marvel Phase Three adventure may be the second movie Joaquin Phoenix regrets turning down. What do you think about these new developments? Chime in with your thoughts below.
