Passage: His father, John F. Link Sr., was also a film editor, and was also nominated for an Academy Award: for the 1943 film, For Whom the Bell Tolls. Link was one of several assistant editors on the film. That same year he was the sole editor on the documentary, Footprints on the Moon. Both the film and the documentary have his credit as John F. Link Jr., making attribution easy. His next project was another documentary, Say Goodbye in 1971, which was nominated for an Academy Award for Best Documentary (Feature). During the 1970s he worked in both television and film. Notable films he edited during this period include: The King of Marvin Gardens]] (1972), starring Jack Nicholson, Bruce Dern, and Ellen Burstyn; the 1973 cult classic Electra Glide in Blue (which he co-edited with two others); Race with the Devil (1975), starring Peter Fonda and Warren Oates; and the 1976 Jeff Bridges' comedy-drama film, Stay Hungry, which also starred Sally Field and Arnold Schwarzenegger.
