9. Rhino - The Amazing Spider-Man 2
Before The Amazing Spider-Man 2 came out, you'd be forgiven if you thought that Paul Giamatti's Rhino was going to be in the movie for more than five minutes.
Trailers, TV spots and promo images had featured him quite heavily, and it looked like he was set for a significant part.
In reality, the marketing was misleading and the character just book-ended the movie, showing up for an initial confrontation with the webslinger before engaging him in the climactic showdown.
Despite the brevity of his appearance, the mechanized suit worn by Giamatti managed to make quite the impression. It was a cool design that looked and felt powerful, and were it not for the actor's awful Russian accent, Rhino would have been an intimidating presence.
This look was a far cry from Rhino's original comic-book costume though.
Rhino was born in The Amazing Spider-Man #43 from 1966. The story follows Aleksei Sytsevich, a thug who undergoes an experiment that gives him a fake skin covering and superhuman strength. Later on, Aleksei is provided with a stronger, removable version of this covering.
The Ultimate Marvel version of Rhino did feature a mechanized suit, but where the Giamatti version was much larger than the wearer and had him climbing into a cockpit in the front, the Ultimate Marvel version was essentially a full-body suit.
