After dropping out of the University of Miami, Andrew Prine began acting in television in the late 1950s with appearances in the live drama series "The United States Steel Hour" and "Look Up and Live," before landing his breakthrough role in 1962 playing Helen Keller's brother in the Oscar-winning "The Miracle Worker." Having developed a southern accent, and capitalizing on the popularity and boom of the western genre in the 1960s and 1970s, Prine would become a regular on television mainly as a supporting actor in western series like "Gunsmoke," "Wagon Train," "The Wide Country," and "Bonanza." It was also during the 1960s and 1970s that he appeared in films alongside the likes of John Wayne in the western "Chisum," Dean Martin in the western "Texas Across the River," and William Holden in the war drama "The Devil's Brigade." Prine would continue to land guest roles on television throughout the 1970s and would even write his own dialogue for the "Jaws" inspired horror film "Grizzly" in 1976. Although Prine's most notable roles were behind him by the 1980s, he continued to appear in films and TV series in more supporting roles in works like the sci fi mini-series "V: The Final Battle" and the action film "Chill Factor" before returning to a more leading role in the 1993 war epic "Gettysburg." Prine would also appear in an episode of the police procedural "CSI: Crime Scene Investigation" in 2005 under the direction of acclaimed filmmaker Quentin Tarantino.
