However, it seems that during filming, the visual effects team had some problems with one particular Pokemon, Mr. Mime.
Detective Pikachu is now out and is now the most successful movie based on a video game.
But in the end, Mr. Mime ended up being such a character in the movie that he became one of the most popular Pokemon there.
Visual effects supervisor Erik Nordby and creature art director Ravi Bansal went directly to the Pokemon Company to ask advice on how to adapt Mr. Mime on screen.
