Kevin Feige Explains Why Marvel Spoiled Dafne Keen’s X-23 Return in Final ‘Deadpool & Wolverine’ Trailer

Michaela Zee “Deadpool & Wolverine” has been pegged as a cameo-filled affair that sees the return of several mutants and other beloved characters in the Marvel Cinematic Universe.

While the majority of these appearances have remained a secret, Marvel let one surprise out of the bag in the final trailer for the superhero threequel: the return of Dafne Keen’s X-23 from the 2017 film “Logan.” According to Marvel chief Kevin Feige, there were a few reasons why the studio decided to spoil the X-23 surprise one week before “Deadpool & Wolverine’s” theatrical release. “Dafne really wanted to go to the premiere and we said, ‘Well, she really can’t come to the premiere because it would be a spoiler.’ We hadn’t shown it yet,” Feige told Variety at the “Deadpool & Wolverine” premiere on Monday night in New York City.

Luckily for Keen, Disney wanted to unveil the character in the trailer because X-23’s appearance teases “an emotional core of the movie,” Feige explained, adding that Disney marketing knows “exactly when to push a little forward and pull a little back.” Marvel ultimately agreed that X-23 should be included because, Feige said, “it was great in the final trailer” and “that meant Dafne could come to the premiere.” “Deadpool & Wolverine” marks the return of Hugh Jackman as the animalistic mutant after saying farewell in “Logan.” Ryan Reynolds, who dons the Merc with a Mouth’s red suit for the third time, said he and Jackman wanted the film to deliver two things: joy and a complete experience.
