5. Made Norman Osborn The Green Goblin
A leaked photo from the set of The Amazing Spider-Man 2 revealed that there was at one point a plan to tease the return of Norman Osborn following his death earlier on in the sequel. As moronic as it sounds, the scene involved The Man in the Hat approaching Norman's decapitated head in a jar and promising to find a way to bring him back. Had they somehow found a way to bring back Norman, having him become the Green Goblin - preferably the Ultimate version rather than whatever the hell Harry Osborn was supposed to be in The Amazing Spider-Man 2 - could have been what the series needed. Casting the 63-year-old Chris Cooper as the villain always seemed like an odd choice, but that's nothing a fully motion-captured version of the Goblin couldn't have fixed. Harry could have even been killed off in prison off screen to explain why Norman returns looking for revenge, and if Sony were really desperate to tell the story of Peter Parker's parents, then even that could have all tied into the Goblin coming after Spider-Man. If Sony really wanted to shake things up, the movie could have ended with both Peter and Norman dying, only for a mid-credits scene to reveal the debut of the young Miles Morales.
