Keen only got to play Laura, aka X-23, the one time in “Logan” when she was just 11. At one point, Fox had plans to make an X-23 spin-off movie with director James Mangold involved. However, once Disney purchased Fox, those plans fell through. The door re-opened eventually once Jackman decided to pick up the claws once more for this film. Up until now though, Keen had to keep her involvement a secret.

“I had to do a bunch of press for a job that I just finished,” Keen said in an interview with Entertainment Weekly about her return to the Marvel universe, alluding to her role in the “Star Wars” series “The Acolyte” on Disney+. “I got asked in every interview, and I just got to lie, which was really funny.” Keen also talked a bit about that scrapped movie that never came to be, revealing that it was sad having to say goodbye to that character.

“I was quite sad. I was like, ‘Oh well, I guess that’s it. That’s life, and I’ll have to move on’ — even though this is one of the greatest characters I’ll ever get to play, and annoyingly, I got to play her at 11! I peaked at 11.”

However, her agent had been negotiating in secret with Marvel to get her in “Deadpool & Wolverine.” When the call finally came in, Keen was thrilled. “I immediately screamed. I dropped my phone in the bath. I had to put it in rice; it was a whole thing.” While Keen was nervous to get back into Laura’s shoes after all these years, she also said that once the cameras started rolling, it was like doing “Logan” all over again.

“As soon as they said, ‘Rolling!’ I really felt like we were back doing Logan. It was like eight years hadn’t passed.”
