Warner Bros.



"Detective Pikachu" is ready for the next case. A sequel to the Pokemon-based movie is already in the works, months before its May 10 opening.

Producer Legendary Pictures has hired Oren Uziel to write the sequel's script. The move is a vote of confidence in the film's potential box office reception. Details about the sequel's direction or plot are unknown.

In the video and card game, Pokemon are cute, powerful monsters that are collected by player trainers and used in battle tournaments.

Pikachu is a species of Pokemon, and Detective Pikachu an investigator good at finding things.

Ryan Reynolds voices Detective Pikachu in the movie (and provided facial expressions in motion capture). Justice Smith plays former Pokemon trainer who teams up with the Detective and is the only person capable of hearing him speak.
