JEJ did indeed play Thulsa Doom in CONAN THE BARBARIAN. BTW, the director of that film, John Milius, is a long-time member of the NRA and has been partially blacklisted in Hollywood ever since RED DAWN in 1984.
Want to see a GREAT movie? Rent Milius' THE WIND AND THE LION sometime. A fictionalization of the "Pedicarus (Sp?) Incident". American Marines invade a lawless Arab country, free the hostages, and overthrow the government -- much to the dismay and scorn of European diplomats and other cheese-eating surrender monkeys.
One of the greatest lines from a movie EVER came from "THE WIND AND THE LION" when Teddy Roosevelt was told that sending Destroyers into the region was "illegal" His answer?
"Why spoil the beauty of a thing will illegality?"
