8. Benicio Del Toro - Darth Maul
One of - if not the - most exciting things about the first Star Wars prequel was the anticipation to see just who would fill Darth Vader's boots and pose a significant enough threat to the galaxy to warrant three more films. We thought Maul was our man. Alas, no - he was but a pawn, and a pawn with very few lines at that. Now, rumour has it Benicio Del Toro was all set to don the face paint and fake horns until Lucas unceremoniously cut out the majority of the character's lines. This made Del Toro uncomfortable, unsure as to whether there was enough character development for him to work with as an actor. As a result, he left the project to be replaced by Ray Park (who later went on to have roles in X-Men and G.I Joe but little else of note) and Darth Maul, while undoubtedly badass with that double-edged lightsaber, was reduced to little more than a stuntman who'd forgot to take off his devil costume after Halloween. Perhaps Del Toro made a good call - Darth Maul has a total of three lines over the course of the film.
