He began acting in plays in Seattle, WA. He earned his Screen Actors Guild card with a minor role in the 1991 film My Own Private Idaho. He then moved to Los Angeles to pursue a career in acting.

He was offered a scholarship to study acting at NY's Juilliard School in 1993, but turned it down to portray Warren Earp in the 1994 film Wyatt Earp. He later appeared in episodes of Murder, She Wrote and The Wonder Years. After appearing in G.I. Jane (1997), he had a breakthrough performance in the 1998 Terrence Malick World War II film The Thin Red Line.

During filming, he was struck by lightning, accidentally scourged, had his shoulder dislocated, and suffered from pneumonia and hypothermia. Prior to filming, Gibson reportedly warned Caviezel that playing Jesus in his controversial film would hurt his acting career. In 2011, Caviezel claimed that good roles had been hard to come by since, but stated that the movie, in particular the role of Jesus Christ, was a once-in-a-lifetime experience.
