Alf Gunnar Helgesson Kjellin (28 February 1920 – 5 April 1988) was an actor and director born in Lund, Skåne län, Sweden. He made his film acting debut in his native Sweden in 1937, and his work in Hets (1944) resulted in his being noticed by Hollywood. He made his American film debut in Madame Bovary (1949), briefly adopting the name Christopher Kent. He soon went back to using his real name, and for the next decade he appeared in several more Hollywood films and TV drama anthology series whilst also working in Sweden as both an actor and director. In the early 1960s he finally settled in Hollywood. There, he concentrated on directing for TV on such shows as The Alfred Hitchcock Hour, Dr. Kildare, The Man from U.N.C.L.E., I Spy, Mission: Impossible, Hawaii Five-O, The Sixth Sense, The Waltons, Planet of the Apes (episode "The Interrogation") and Dynasty, as well as TV movies like the clever psychological thriller Deadly Dream (1971), but continued to make a few appearances as a guest star in TV series and on film, his most recognisable role being the Russian paratroop commander in Ice Station Zebra (1968). Kjellin died in Los Angeles of a heart attack.
