All three said there is going to be a sequel, and Moore even gave us the inside scoop on what classic Nintendo character he'd like to see in the sequel.
“They wouldn’t make [all that] merchandise, if [Disney] didn’t have plans for other [Wreck-it Ralph] stories.
“Some of the big muckety-muckets at the studio, who I just saw the other night, were like ‘We’re talking sequel!’. The movie made $150 million dollars in eleven days, it broke the box-office record for Disney animated movies on opening weekend. If that’s any indication that we’ll be doing a sequel… I bet we’ll be doing a sequel.”
“At dinner last night we were already talking about. So we’re talking ‘what could do they do? what kinda of things could happen? who could be in it?
“I love the group, I’d be crazy to ask someone else to take the reigns.
“We’ll really come up with something good for Mario to do [in the next film]. To be able to present him in the sequel, would be great."
Wreck-It Ralph was a great, fun flick. If you haven't seen it I highly recommend you do so immediately.
