Frost had a starring role in Gus Van Sant's 2003 film Elephant, in which he played a high school student who commits a school shooting. The film was set in Frost's hometown of Portland, Oregon, with the director avoiding Hollywood actors in order to find real local teenagers. Frost's musical experience was a key factor in him auditioning for the role.

He played the primary antagonist in the Owen Wilson movie Drillbit Taylor, released on March 21, 2008, by Paramount Pictures. He appeared in two films in 2009, Calvin Marshall and The Vicious Kind.
