I don't know if everyone will agree with these, but here's where I saw similarities to these movies----
Treasure Island- Where Wilt comes upon an old sea captain in a rocking chair, he first struck me as Long John Silver
Star Wars- "Princess Amacoco", and also what she's wearing
Peter Pan- When the pirate ship lifts off the water and flies away
Planet of the Apes- The futuristic jungle scene with the dinosaur and "Tom Hanks"
Harry Potter- "Three wizards from the wrong side of the tracks", and them all using their "magic" against eachother
Rush Hour- Coco trying to deactivate a bomb before it explodes in "2 seconds"
And I think I thought of another one, although I don't remember actually seeing the movie so I don't know how well a spoof it is, but when Wilt transforms into a....what? Furry thing? Could that be a spoof from "An American Werewolf in London"? Or maybe "Gremlins"?
