SPOILERS! SPOILERS! SPOILERS! SPOILERS! SPOILERS! From the Star Wars Homing Beacon newsletter, on the second season of CLONE WARS >>Known to many fans as the voice of Bender on "Futurama," John DiMaggio not only plays a Padawan in the micro-series, but is also the menacing voice of General Grievous in the series. General Grievous is an Episode III character who makes his debut in the final episode of Star Wars: Clone Wars. Don't expect much in common between Grievous and Bender though. The General of the droid army isn't likely to invite any Jedi to bite his shiny metal posterior.
