Willem Dafoe (soon to also be seen in The Hunter) had a unique challenge for his role in John Carter. Dafoe portrays Tars Tarkas, a native of Mars who is the first to meet John Carter (Taylor Kitsch) when he arrives on the planet. You see, in order to play the nine-foot tall creature, Dafoe had to don a motion capture suit and walk around on stilts to accurately convey his character’s height. Then, there’s that whole learning an imaginary language aspect. In our exclusive video interview from the Arizona desert, the esteemed actor let us know which of those was more difficult and also talks about how the infectious enthusiasm of director Andrew Stanton was like a Red Bull for all involved.
