Spider-Man 3 (the original version)

Plot
The Pitch For The Original Spider-Man 3 Is: Tobey Maguire’s Spider-Man would throw Vulture in jail, leaving the latter to stew in his hatred and cook up a plot for revenge; Sandman would become his cellmate and they’d team up to bust out and wreak havoc; in the end, Spidey would offer a truce to Vulture, who would refuse and die during their big fight, thus “illustrating to Peter the ramifications of a heart hardened by an inability to forgive.”
