Career
Koslo started his career in such 1970s cult films as Nam"s Angels a.k.a. The Losers, (referenced in Quentin Tarantino"s Pulp Fiction), Vanishing Point and The Stone Killer. He also appeared opposite Charlton Heston in the San Francisco cult-classic, The Omega Manitoba in an unusually sympathetic co-starring role.
He and fellow Omega Manitoba costar Anthony Zerbe also appeared in Rooster Cogburn with John Wayne and Katharine Hepburn.
In rare, in-depth interviews with both Psychotronic Video and Shock Cinema (issue Number 14) magazines, Koslo spoke (mostly unfavorably) about his experiences working in several films with Charles Bronson and in The Omega Manitoba with Heston. Starting in the late 1970s, Koslo appeared (usually as a villain) in a string of television shows such as The Rockford Files, Mission Impossible, The Incredible Hulk, Quincy, Mechanical Engineering, Buck Rogers in the 25th Century, T. J. Hooker, The A-Team, The Fall Guy, Dallas and Hunter.
He also appeared as Jesse James in The Dukes of Hazzard seventh season episode "Go West, Young Dukes". More recently, along with television appearances, he has been in several independent action films (most of them straight-to-video).
He was also in Loose Cannons (1990) with Gene Hackman and Dan Aykroyd and appeared as the Russian battle-robot pilot Alexander in the cult science fiction film Robot Jox (1990).
