John Drew Barrymore the son of actor John Barrymore and actress Dolores Costello, debuted in films as a teenager, and, during the 1950s, appeared in such notable films as the western High Lonesome, Fritz Lang's thriller While The City Sleeps, and the cult melodrama of the evils of marijuana, Jack Arnold's High School Confidential. He acted in several Italian-made historical films in the early 1960s, including The Nights Of Rasputin (aka The Night They Killed Rasputin) and The Trojan Horse (as Ulysses to Steve Reeves' Aeneas). He entered semi-retirement from the mid '60s through the mid '70s; his later films include Larry Cohen's werewolf comedy Full Moon High. ~ All Movie Guide
