We all expected that director Christopher Nolan would want a nuanced performance out of Aaron Eckhart in order to explore the two sides of Harvey Dent/Two-Face in this summer's The Dark Knight. Well, the director won't disappoint, as is revealed in an article over at CHUD.

According to the article, Nolan used dual takes of Eckhart which will be spliced together to create the characterization of Two-Face. Eckhart would do one take as the "sane" Harvey Dent, and another as the more psychotically insane Two-Face, in make-up. Nolan will then be able to splice the footage from the two takes together to best create the dichotomy in the character.

It sounds like a fascinating technique, and fans should be thrilled with the final results when the film opens this summer.

The Dark Knight opens on July 18, 2008, and stars Christian Bale, Heath Ledger, Morgan Freeman, Gary Oldman, Aaron Eckhart and Maggie Gylenhall.
