Who is the worst Pokémon of all time? It's not Magikarp, because Gyarados is top-tier. It's not Unown, because the third anime movie is fantastic. Even Luvdisc gives you useful items in Heart Scales.

No, the worst Pokémon ever is Mr Mime. Its name doesn't make any sense. It gets outclassed by most Psychic types, and it's just plain creepy.

It's such an irritating Pokémon that it took the director of the upcoming Detective Pikachu movie two whole years to get it in there.

Speaking to IGN, Rob Letterman said he read the script for the Detective Pikachu 3DS game, which featured a scene with a Mr Mime, after recently watching the movie Seven. That's what gave him an idea.

He said: "I thought it would be really funny if we played that classic film noir detective interrogation scene, but with Mr Mime. A classic police interrogation scene ripped out of every detective movie I could think of, but flipped on its head. Because the uncooperative informant that they're interviewing happens to be a mime."

He continued: "I thought no way in a million years would (the scene) work. Honestly. It was so weird. I wanted to cut it at one point, because I was like this can't possibly work. It's insane.

"I went to The Pokémon Company. I was like 'I have this idea for this scene, and it requires realising Mr Mime photoreal into the live-action world'. They thought about it, and... they literally looked at me like, 'yeah you don't wanna do that. That's not gonna work. That's gonna be too weird. That's gonna be creepy'.

"It came to the point where I literally had to ask the President of the whole Pokemon Company, Ishihara-san. I gave him the whole pitch, and he started laughing, and he's like, 'okay, give it a shot'."

Revealing the green screen actor had to wear eyeballs on his stomach to give Justice Smith an eyeline, Letterman added: "It was the most awkward, weird thing to shoot. Just reenacting it for you now is making my head explode. It was bizarre."

We'll admit that brief look at the scene in the trailer is amusing, but we're going to wait until Detective Pikachu releases in cinemas on May 10 to see if it rescues Mr Mime from the title of worst ever Pokémon.
