You may only have seen Aleksei Sytsevich in his rumblin' Rhino suit for a few minutes at the end of the film, but it was definitely a cool piece of Soviet-era hardware. The evolution and genesis of the galloping mech-suit, the Green Goblin and Peter Parker's Spider-Man suit can be seen in these stylish concept images from artists Robert Simons and Kelton Cram. These varied visions changed as the screenplay progressed and represent a more intricate Rhino armor, slimmer Spidey-suit and elegantly insane Green Goblin and his glider.
Take a look and see if you'd have gone with any of these alternate ideas..
