That'll be chaos

Here you go
Edit: it's closed though, but reading the reasons to sign is amusing

Darn it. I'd back that.

It is. And I think that should be fun. But I think Devitto would be more fun and suiting. Ryan Reynolds is a good pick too though IMHO but a grumpy devitto voiced "grizzled detective" pikachu? Man. Make it PG13 or R and have a great film for adult Pokémon fans. Reynolds should be a good "Pixar" solution though that if done right can entertain people of all demographics and appeal to a wider market.
