Reza Badiyi, who holds the Directors Guild of America record for helming more television episodes than anybody in the history of the medium, died Saturday at Ronald Reagan UCLA Medical Center. He was 81. Badiyi was an award-winning documentary filmmaker and actor in his native Iran before moving to the U.S. in 1955; he eventually became a cinematographer and worked with directors including Robert Altman. Badiyi started his TV-helming career in the late ’60s. Among his massive list of credits — which features more than 400 hours of series and movies of the week — are such iconic shows as The Mary Tyler Moore ShowMission: Impossible, The Rockford Files, The Six Million Dollar Man, Cagney & Lacey, Falcon Crest, Baywatch, the original Hawaii Five-0 and Buffy the Vampire Slayer. Last year, he was honored for his 60 years in the entertainment industry with an 80th-birthday celebration at UCLA’s Royce Hall. His last directing credit was the 2006 feature The Way Back Home.
