I know this is virtually impossible to answer accurately on the surface as it'd depend on actors, writers, etc. But what show would like to be adapted from a game or movie? Would it be successful if they did have the right writers, cast, etc?

Comics: Galactus, Sentinels and Dr. Doom. We always see stuff adapted on heroes. But the villains don't get their own series or movie. It'd be neat to explore their beginnings. With the technology available these days, they can make this work. Should be in animated form with the following voices: Don't know their names so gonna go by where I heard the voices. Sentinels (from 90s X-Men TAS) Galactus and Doom (from Ultimate Alliance).

Game: Batman: The Arkham duology. Animation. Voices: The main characters (Batman, Catwoman, Gordon, etc) should be Kevin Conroy and the others from Batman TAS. Hamill said he won't voice Joker after Arkham City so he'll be damn near impossible to replace.

I kinda wanna see Ultimate Alliance be adapted into a series or a movie franchise, but with so many heroes and such, would be hard to keep up with it all so...

Movie: Toy Story. There seemed to me that between 1 and 2 as well as 2 and 3, there were gaps. These could be filled with a series.
