Now this sounds like a fun concept. Rich Moore (TVs THE SIMPSONS and FUTURAMA) is making a feature-length CG animated film for Disney Studios called WRECK-IT RALPH. The concept is an 8-bit video game villain, Wreck-It Ralph (John C. Reilly) is getting tired of being the Bad Guy all the time, fighting against Fix-It Felix (Jack McBrayer), so he tries to rehabilitate his image and become a Good Guy at the arcade. He jumps into a first-person shooter featuring Sergeant Callahan (Jane Lynch), but something happens in the game that releases a powerful nemesis that threatens all the games in the arcade.
I love the idea of different video game characters interacting with each other. What's unclear from the press release is if other franchised characters would appear in the film. I'd love to see Mario and Pac-Man take on the Berzerk robots. But I really like the cast, which includes Sarah Silverman as the voice of a "glitch" character from a kiddie racing game that helps Wreck-It Ralph on his quest to become a hero. WRECK-IT RALPH will be released by Disney on November 2, 2012. Here's the press release:
Will Deadpool and Wolverine end the MCU losing streak?
Deadpool & Wolverine wakes up the superhero genre with a swift kick to the taint.
The Beast Within asks if the beast is a mask or the true form.
I think it will advertise their own games more than anything. It sounds interesting, but this is simply Disney trying to find something new to play with.
Based on their booth at E3, they have absolutely no plans to change the game industry in any ways. Almost everything they had was casual wii titles.
