Richard C. Sarafian, a Hollywood director best known for the speed-addled saga of squealing brakes and existential angst chronicled in the 1971 cult film "Vanishing Point," died Wednesday. He was 83. Sarafian was recovering from a broken back when he contracted pneumonia, family members said. He directed numerous films and, earlier in his career, TV shows that included episodes of "Gunsmoke," "The Twilight Zone" and "Batman." He also acted, appearing as hitman Vinnie in the Warren Beatty satire "Bulworth" and gangster Jack Dragna in Beatty's "Bugsy."
