Star Power ' Star Wars: The Clone Wars' Forget about Hayden Christensen, Ewan McGregor and Natalie Portman. This voice cast is mostly unknowns, with the exceptions of Samuel L. Jackson, Anthony Daniels and Christopher Lee, who were able to reprise their live-action roles. ' Tropic Thunder' Ben Stiller, Jack Black and Robert Downey Jr. are huge on the poster, but the film also has Nick Nolte, Steve Coogan, Matthew McConaughey and Tom Cruise in heavy (and hairy) make-up. WINNER: Hands-down, Tropic Thunder is top-heavy with A-list names. Theres no part that gets Hollywood actors more worked up than a chance to play Hollywood actors.
