In the version that showed on Cartoon Network, there were many cuts for time, violence, and swearing. All uses of ass, hell, and damn were scrubbed from the movie (i.e. Goblin says "we're gonna have [an interesting] time" as opposed to a "hell of a time"). References to religion were also trimmed. There is also an alternate angle of Norman getting impaled that is less violent.
A scene that was cut from the movie was a large chunk of Stan Lee's cameo, as said in the video "Stan Lee's Mutants, Monsters, and Marvels." The scene was that Stan Lee was selling sunglasses and looks over to Peter Parker and says: "These are the same glasses that the X-Men wore," or somewhere along those lines.
