Spider-Man 3

Two years after Otto Octavius's sacrifice from his experiment, Peter Parker plans to propose to Mary Jane Watson, who just made her Broadway musical debut. Later, a meteorite lands at Central Park, and an extraterrestrial symbiote follows Peter to his apartment. Harry Osborn, seeking vengeance after his father's death, attacks Peter with weapons based on his father's Green Goblin technology. The battle ends in a stalemate with Harry crashing out and developing amnesia, wiping out his memory of Peter as Spider-Man. Meanwhile, police pursue escaped convict Flint Marko, who visits his wife and dying daughter before fleeing again. While being chased by the police, he falls into an experimental particle accelerator that fuses his DNA with the surrounding sand, transforming him into the Sandman with powers to control sand and to deform at will.
