Actor who played Lojur, helmsman of the USS Excelsior under Captain Sulu, in Star Trek VI: The Undiscovered Country and again in the Voyager episode Flashback.
Boris Lee Krutonog, also credited as Boris Krutonog, is an actor and producer who has often played Russian characters in American films, among them The Hunt for Red October.
In Star Trek VI: The Undiscovered Country (1991) he played the Excelsior's helmsman, who is at his station when the shock wave from Praxis strikes the ship and later during the dash to Khitomer. The character's name, Lojur, comes from the script rather than the dialogue.
He was one of the Excelsior players brought back for the Voyager third-season episode Flashback (1996), which revisits the same events through Tuvok's memories of serving under Sulu.
