Spiderman the Movie Cheats

Successfully complete the game under the hero or super hero difficulty setting to unlock the Green Goblin costume option at the specials menu. Select that option to play as Harry Osborn in the Green Goblin costume with his weapons in an alternate storyline where he tries to correct the Osborn family's reputation.

Alternate Green Goblin costume:
If you are using the Alex Ross Spider-Man, play any level with the Green Goblin in it and he will have an alternate costume that resembles his classic costume more. Note: This will only work when you are in the Alex Ross costume and the Green Goblin alternate costume will not be in the very last in-game intermission.

Play as Peter Parker:
Successfully complete the game under the easy or higher difficulty setting to unlock the Peter Parker costume in the specials menu.

Play as wrestler:
Successfully complete the game under the easy or higher difficulty setting to unlock the wrestler costume in the specials menu.

Go to the options menu then to the cheats screen and put in the code THUGSRUS . The Green Goblin will laugh if you entered the code correctly

Enter these codes in the Cheats section under the Specials menu. Enter the code a second time to deactivate:

In any fight against the Green Goblin, you can hang on to his glider just as in the opening FMV sequence. While swinging or on foot, you can either target his glider and press Web Zip or face him and do it manually. This will allow you to hang on to his glider while he flies around. This is difficult and risky at first.

In a storyline that mirrors the main game, you play as Harry Osborn (in his
dad's costume and with the Goblin's arsenal of weapons) out to right the Osborn
family name.

level.
