It's an adaptation that's more than a decade in the making and, for Reynolds, it's a way to regain some face saved by starring in a pair of notorious superhero flops.
The way he hopes to do so is to go exactly the opposite of what everyone else has done; where X-Men Origins and Green Lantern were mega-budget movies, Deadpool is a film where Reynolds jokes he's wearing his own clothes on set to save wardrobe money.
And while that massive investment in most superhero films forces some creative compromises, Reynolds says Deadpool won't be like that -- and that they're making a movie they hope will appeal to the hardcore fans as much or more than the casual viewer.
"We've got a director that understands that world, and writers with a slavish devotion to the canon of that character," Reynolds said, echoing sentiments he's used before. "That's the most important aspect: it's made in a way the most critical of fanboys could embrace. Well, that's the hope."
Reynolds -- and everyone else -- will find out on February 12, 2016.
