"Guardians of the Galaxy Vol. 2" was almost a little more "Interstellar." Speaking to Playboy, Academy Award-winner Matthew McConaughey discussed why he passed over "Guardians of the Galaxy Vol. 2" to star as the villainous Man in Black in Sony's "The Dark Tower."

"I like 'Guardians of the Galaxy,' but what I saw was 'It’s successful, and now we’ve got room to make a colorful part for another big-name actor.' I’d feel like an amendment," McConaughey explained. "'The Dark Tower' script was well written, I like the director [Nikolaj Arcel] and his take on it, and I can be the creator, the author of the Man in Black -- a.k.a. the Devil -- in my version of this Stephen King novel. We’ve done the first one. It’s a fantastic thriller that takes place in another realm, an alternate universe, but it’s very much grounded. For instance, the gunslinger’s weapon isn’t a lightsaber or something; it’s a pistol. I enjoyed approaching my character as if I were the Devil having a good time, getting turned on by exposing human hypocrisies wherever he finds them."

It's unclear which role McConaughey would have played in "Guardians of the Galaxy Vol. 2," and he certainly doesn't offer any clues here. It's possible he could have appeared as Star-Lord's father Ego the Living Planet, who will be played by Kurt Russell. Alternatively, we still don't know who the main villain of "Guardians" will be, so he could have also filled that role. Unfortunately, until someone involved behind the scenes comes forward, we can't know for sure.

This isn’t the first time McConaughey has been linked to a superhero property. A previous rumor linked the actor to “Spider-Man,” with Marvel reportedly eyeing the actor to play Norman Osborn, though nothing came of that rumor. However, he isn't opposed to appearing in a live-action comic book film. Early last year, he said, “I’ve read some Marvel and DC scripts and I’ve talked about working with them on some scripts, none of which I’ll share with with you what they are – or were... Yeah, I’ve circled some of those. Nothing has been right for me yet. But I’m sure open to it.”

Opening May 5, “Guardians of the Galaxy Vol. 2” also stars Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Michael Rooker, Karen Gillan, Sean Gunn, Glenn Close, Elizabeth Debicki and Chris Sullivan. “The Dark Tower” opens July 28 and stars Idris Elba, Matthew McConaughey, Abbey Lee, Katheryn Winnick, Tom Taylor, Fran Kranz, Claudia Kim and Jackie Earle Haley.
