Among the many aspects of the film that worked in unexpected ways his mask deserves some notes onto itself. They really made it actually bend and emote more than I thought was possible, and thus pulled off many of the mask/face expressions. I did not even think it was even possible though fabric and what not. Aside from wanting to express appreciation for the effect small details can have, I wonder if anyone knows if there was some SF-wizardry at work or did they find a simple solution? Considering the budget I don't think they used anything too complex/expensive.
