Most people haven’t seen Deadpool 2 on the big screen yet, but as with its predecessor, the marketing campaign for the film has felt like a major entertainment event in and of itself.

We’ve seen everything from parody posters to bizarre product tie-ins to an apology for David Beckham, but perhaps the most surprising and amusing Deadpool 2 marketing coup of them all was landing Celine Dion to sing the film’s theme song, “Ashes.”

The song, done very much in the style of both ’90s action-movie tie-ins and Bond films, is cleverly worked into Deadpool 2, but even if it was only a promotional tool it would be kind of extraordinary.

Deadpool certainly has more clout in Hollywood than he did a decade ago, but it was an impressive feat even for the Merc with a Mouth, and in a recent interview Ryan Reynolds explained how it happened.

While appearing with his castmates and director David Leitch at a recent AOL Build panel, Reynolds said he should get “Some sort of award” for getting fellow Canadian Dion to be a part of his movie, then detailed how it all went down.

“So we got a way in through her manager. I sent her a long letter describing what Deadpool is and what we’re hoping to do, and somehow she got… two hours later or something, she said yes. And then we said, ‘How about a video?’ and she said yes to that, too!”.

It likely doesn’t exist, but footage of Celine Dion reading that letter, learning what Deadpool is perhaps for the first time, would be endlessly compelling.
