De Antonio was already forty when he became involved in filmmaking. He produced two early films of the New York Beat movement, “Pull My Daisy” (1959, Robert Frank, Alfred Leslie) and “Sunday” (1961, Dan Drasin), the latter also featuring in the 2025 Retrospective. He was also one of the founding members of the New American Cinema Group, along with Jonas Mekas, Shirley Clarke and others. “Point of Order!” became his directorial debut, the first cinema film compiled exclusively from television images. From 188 hours of material of the “Army–McCarthy hearings”, a tribunal broadcast live from the Senate in 1954 in which the notorious communist hunter Joseph McCarthy had to face an investigative committee, de Antonio distilled a farcical show trial at the end of which everyone involved looked like a convicted criminal.
