Aaron Edward Eckhart (born March 12, 1968) is an American actor. Born in Cupertino, California, Eckhart moved to the United Kingdom at an early age. He began his acting career by performing in school plays, before moving to Australia for his high school senior year. He left high school without graduating, but earned a diploma through a professional education course, and then graduated from Brigham Young University (BYU) in Utah, U.S., in 1994 with a Bachelor of Fine Arts degree in film.

As an undergraduate at BYU, Eckhart met director and writer Neil LaBute, who cast Eckhart in several of LaBute's original plays. Five years later Eckhart made a debut as an unctuous, sociopathic womanizer in LaBute's black comedy film In the Company of Men (1997), followed by appearances in three more of the director's films.

Eckhart gained wide recognition as George in Erin Brockovich (2000), and, in 2006, he received a Golden Globe nomination for his portrayal of Nick Naylor in Thank You for Smoking. In 2008 he played a major role in Christopher Nolan's blockbuster Batman film The Dark Knight as District Attorney Harvey Dent / Two-Face.

In 2019 he starred in Roland Emmerich’s blockbuster Midway.
