Aaron Eckhart, who plays District Attorney Harvey Dent in The Dark Knight had previously said that playing the role required exploring the differences between his character and that of Batman. At the Independent Spirit Awards, Eckhart told MTV Movies Blog what he discovered while working on the film.
"Well, they're both crime fighters," he said. "They both care about law and order. They both care about Gotham City. Although they come from different backgrounds, they share certain things." Eckhart then added, "[Things that] I cannot tell you about."
As much as that comment invited speculation, Eckhart was unable to clarify - even going so far as being unable to confirm if his Harvey Dent would transform into Two-Face during the film. "I can't comment on anything. I'm sorry. You gotta ask, but literally, if I ever want to work in this town again, I cannot say anything to you," Eckhart teased, smiling. "[Chris Nolan] is a good man, but he's a tough man."
Eckhart would, however, reveal that he shares a scene with Heath Ledger's Joker in the film. "I had a wonderful time working with Heath. I had the chance to watch him shine in this movie," Eckhart said. "I am glad that I was able to be in the same room and watch him work."
The Dark Knight opens on July 18, 2008, and stars Christian Bale, Heath Ledger, Morgan Freeman, Gary Oldman, Aaron Eckhart and Maggie Gylenhall.
