It's been a long road for Ryan Reynolds' "X-Men" movie spin-off "Deadpool," but after over a decade of work the merc with the mouth is finally coming to the big screen in 2016. With filming scheduled to begin in just a few short months, when MTV News caught up with Reynolds at the Sundance Film Festival where his new movie "Mississippi Grind" had just premiered, we had to ask him about the project.

Turns out, he wasn't surprised at all that we wanted to know more.

"The budget isn't what we hoped it would be, this is actually the suit," joked Reynolds, pointing out his surprisingly Deadpool-costume colored flannel shirt.

More seriously, Reynolds underscored that though the movie had been in the works for a while, and had a few hiccups -- including a turn as the character in "X-Men Origins: Wolverine" that some fans were less than pleased with -- he's happy about how it all turned out.

"It's been a long time, but it's happened in the right way and that's all that matters," Reynolds said. "We don't have the kind of money that most superhero movies do, but that's great, actually. Necessity is the mother of invention, and that's why we get to make the movie we want to make."

Reynolds has played another superhero on screen: DC Comics' "Green Lantern," which premiered to mixed fan and critical reviews in 2011. So with that hanging over Reynolds' head, is he feeling more pressure to deliver when it comes to Marvel's wise-cracking killer?

"No, no, no, of course not," Reynolds continued. "You gotta have faith in the people you're working with, and have faith in the prep, and that's all I'm doing. On this one, the prep's been 11 years. You'd like to think you're putting your best foot forward, but we'll see."

Though there's not necessarily a direct correlation between the two, mere months before "Deadpool" was greenlit by FOX, test footage featuring Reynolds' comic-book faithful take on the character leaked online. To outsiders, at least, it seemed that the rapturous response to the minutes long action sequence was exactly what was needed to get the movie going.

So did Reynolds leak the footage himself to give the process a kick in the butt? No way.

"I would have FOX's lawyers so far up my ass they could smell Wade Wilson's feet," Reynolds joked. "No, no, no I didn't leak it. But I would have. Looking back now, in a heartbeat. I should go home and scan the old hard drive and see what I've got in there."

"Mississippi Grind" is now playing at the Sundance Film Festival.
