Lilo and Stitch didn't really cause any controversy with audiences, but it sure caused problems for the crew at Disney's Hollywood Studios during the making of the film.
It seems Lilo and Stitch was originally going to be a much more violent film, with lots of sci-fi violence and a star who broke all the rules regarding good guys in animated features for kids.
So the film underwent some radical changes thanks largely to test audiences who felt certain scenes in the film were too violent.
The scene where Jumba the alien stops sneaking around and goes for a full frontal assault on Stitch, ultimately destroying Lilo's home, was the main scene in need of alteration.
So they started toning down the scene by changing Jumba's laser gun blasting into household destruction via dishware.
The production team didn't agree with the changes made to that scene, but there's one scene they all agreed to alter- the ending scene where Stitch hijacks a 747 to go after Captain Gantu.
The film was in production during 9/11, and even though they'd finished animating the scene they knew it had to go, so the 747 was replaced with Jumba's spaceship and the fight moved from the city to the mountains.
