There's no denying that Illumination's Mario movie was actually pretty good. However, I personally think it could've used a bit more polish to make it even better.

There are some nitpicks I have with the film but the biggest ones are the runtime, Luigi being sidelined for most of the film, the pop songs, and some of the casting choices.

Here's a list of actors I would've picked:

• John DiMaggio as Mario
  (I imagine John would use his Jake voice from "Adventure Time". Also, since John would voice Mario, Uncle Arthur would probably be voiced by Maurice LaMarche.)
• Nicole Oliver as Princess Peach
  (It would be pretty cool if Nicole went from voicing the princess of Equestria to voicing the princess of the Mushroom Kingdom.)
• Kate Higgins as Pauline
• Samantha Kelly as some background Toads
• Tru Valentino and Frank Todaro (The voices of Cuphead and Mugman respectfully) as the two Toad guards of Peach's castle.
• Rob Paulson as Kamek
• Either Brian Doyle-Murray or Bill Farmer (The voice of Hop Pop from "Amphibia") as Cranky Kong

Also, what if Donkey Kong and Bowser had two voice actors?

• When DK speaks, he's voiced by Dan Castellanetta (because he's voiced monkeys before). But when he does his usual in-game grunts and yells, he's voiced by Takashi Nagasako (DK's original voice actor). Just imagine hearing Takashi doing DK's Tarzan yell before DK himself enters the Arena of Kong.

• As for Bowser, he's still voiced by Jack Black. But when he's enraged to the point where he acts like a savage animal who can't talk, that's when Kenny James (Bowser's original voice actor) takes over. This voice change would probably happen during the climax.

Anyway, I just wanted to get all that off my chest. But now with that out of the way, here's a question I have for you guys.

If you could make any changes to the Mario movie, what would you change and why?
