Aaron Edward Eckhart (born March 12, 1968) is an American film and stage actor. Born in California, he moved to England at 13 when his father relocated the family. Several years later, he began his acting career performing in school plays. Eckhart then moved to Sydney, Australia, for his high school senior year; he left without graduating but earned a diploma through an adult education course. In 1994, he graduated from Brigham Young University (BYU) with a Bachelor of Fine Arts degree in film. For much of the mid-1990s, he lived in New York City as a struggling, unemployed actor.

Under LaButes guidance, he worked in the directors films Your Friends & Neighbors (1998), Nurse Betty (2000), and Possession (Possession (2002 film)) (2002).

In 2000, Eckhart gained wide recognition as George in Steven Soderberghs critically acclaimed film Erin Brockovich (Erin Brockovich (film)).
