I had an amusing thought today:
Spider-man and Transformers may actually be the same movie.
You have a young man, crushing on a girl who is out of his league (by society's understanding) and shirking his chores because of his identity concerns. He thinks a car will solve his problems, and the action goes from there. If Peter had gotten the money from the wrestling match and bought a yellow Camaro, the whole Spider-man movie could have gone a whole different way.
Green Goblin: I could squash you like a bug right now, but I'm offering you a choice. Join me! Imagine what we could accomplish together... what we could create. Or we could destroy! Cause the deaths of countless innocents in selfish battle again and again and again until we're both dead! Is that what you want?
Optimus Prime: At the end of this day, one shall stand, one shall fall!
cut to 30 seconds later, and the smear that is left of the Green Goblin. Optimus is looking over it philosohically
"You left me no choice, brother"
the CGI costs would have been truly horrific though, on that version
