A game like Ratchet and Clank will work well as an animated movie as the characters already have well established personalities with good storylines too so you just have to simply bring these to the big screen and add a bit more depth here and there. Marios characters have as much personality as the Teletubbies and story are pretty much non-existent in Mario games so translating the series into a movie is a bad idea.

I don't know but I have a great Idea on the story! Princess peach gets kidnapped and Mario and friends will have to save her.

I know, it's genius!

but seriously if done well it could do really good

if its made by pixar everything is possible even 500 mil.

ooooooh such a huge budget for this movie:O:O:O:O:O:O:O...21million box office isnt a failure...the excessive budget making this looking a failure:P

Read again.

I don't think that'd work. I'd rather watch a Sonic movie!

I believe he has plenty personality to carry a movie. Hes basically Indiana Jones. 

not very much at all tbh.

I know I am just restating previous comments but if Nintendo partnered with Disney or Pixar, then and only then would I support the idea and believe that it could be a box office success.

Anything that have earning of half the expenditure is a failure, at least commercialy speaking.
