The Omega Man
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 science fiction cult-classic, "The Omega Man", in an unusually sympathetic co-starring role. He portrayed villains in "Joe Kidd" (1972, starring Clint Eastwood), "Mr. Majestyk" (1974, starring Charles Bronson), and "The Drowning Pool" (1975, starring Paul Newman).
