In one part of the film, Vanellope von Schweetz (Sarah Silverman) finds herself at OhMyDisney.com (a real website), which houses all of the studio's iconic characters, like every single princess put to celluloid. There are also the properties from Pixar, Marvel, and Lucasfilm to consider. At one point Vanellope is chased by a group of stormtroopers into a room housing all of Disney's princesses.
So, it's no secret that there was a good amount of synergy, cooperation, and leeway among the different branches of Disney, but there was one thing the sequel could not get away with, and that was ribbing on Kylo Ren, the villain of the new Star Wars trilogy, played by Adam Driver.
Speaking to IGN, co-director Rich Moore said:
"At one point we had a joke about Kylo Ren being kind of a spoiled child. We went to Lucasfilm and said, here’s what we’re doing. And they said, well, we’d prefer that you don’t show him as a spoiled child. You know, he is our villain, and we’d prefer you don’t do that. So we were respectful of that.”
While many (including this Twitter account) would argue that Ren (son of Han and Leia) is just a goth kid rebelling against his parents and uncle, the character did become the de facto leader of the First Order by the end of Star Wars: The Last Jedi. Since he is now the driving force (pun intended) behind wiping out the Resistance, it is important for Lucasfilm that their audience doesn't see him as a spineless and whiny weakling with daddy issues.
According to Moore, none of the jokes (which he described as "playful jabs") aimed at established Disney franchises, characters, and icons were done with any ill will in mind.
“[They] honor who these characters are," he said. “It’s really loving satire that we’re doing.”
Wreck-It Ralph 2 arrives in theaters Nov. 21, while Star Wars: Episode IX doesn't drop until Dec. 20 of next year.
