Even as Avengers: Infinity War continues to smash box-office records with no hint of slowing down, the creative forces behind the summer's next big comic-book blockbuster Deadpool II are gearing up to try to smash some records of their own.

Despite the pervasive ultraviolence and wisecracking comedic elements that set the Deadpool franchise slightly apart from its fellow superhero films, the producers for Deadpool II contracted GRAMMY-winning singer Celine Dion to spearhead the performance of the movie's theme song "Ashes," which hearkens more to the balladic laments of her previous contributions to films such as Titanic than to an R-rated action-comedy.

Yet although the song is both somber and moody, it is possessed with the same beauty and depth of feeling of Dion's best works, and its thoughtful motif is clearly an intentional choice by makers of Deadpool II, as seen in the new music video, where musical sentiments serve as an obvious foil to lead character Deadpool's absurdist fourth wall-breaking actions.

Though the music video opens in rather traditional fashion, with Dion garbed in operatic diva fashion standing alone on a stage in an empty theater, we soon see Deadpool pirouette out onto the stage and engage in a performance of contemporary interpretive ballet decked out in stiletto heels.

Though it's obviously doubtful that actor Ryan Reynolds himself is the one inside the suit during the expertly-executed dance routine, we are indeed treated to a vocal cameo from the film's lead actor at the close of the video via a hilarious skit that's definitely worth sticking around for.

Deadpool II will open in theaters everywhere on May 18. The film hopes to break the box office records set by its predecessor Deadpool, which achieved the highest-ever opening worldwide ticket sales numbers for an R-rated film.
