Ahead of Detective Pikachu's next trailer, star Ryan Reynolds shared his process behind his role as the titular Pokemon.

In a video posted by the actor, Reynolds jokes that he attempted to lose weight to match the tiny Pokemon before being saved by his doctors. "You know, I lived it and I breathed it; I became the character," Reynolds declared. "I spent the entire year as Detective Pikachu."

"I vanish in my roles," Reynolds brags. "I was on my way to pick up my daughters from school when I heard that I got the role. Well, I didn’t show up at school, because Detective Pikachu, he doesn’t know who those two little girls are.”

Directed by Rob Letterman, Detective Pikachu stars Justice Smith, Kathryn Newton, Ken Watanabe and the voice of Ryan Reynolds. The film opens in theaters on May 10.
