At the 1977 Academy Awards ceremony, the Best Actor award went to Peter Finch for his performance in Network. Since Mr. Finch had passed away, someone had to be designated to accept on his behalf. (They stopped doing this at some point, at least on the lesser awards. I'm not sure if they still do it on the major ones.) Anyway, the Finch family and all his friends wanted the accepter to be his widow, Eletha. The Academy said that was not possible. After 1972 when Marlon Brando dispatched Sacheen Littlefeather to accept — actually, decline — his award for The Godfather, the Academy made a rule: A substitute accepter had to be a member of the Academy. Eletha Finch was not.
So they found a way around their own rule. Paddy Chayefsky, who wrote Network and was an Academy member, was selected to accept. When Finch won, Chayefsky got to the podium and called the widow to the stage to accept the trophy. On some interview show the next day, he said, "What were they going to do? Have Security tackle her on her way to the stage and wrestle her to the ground to stop her?"
But obviously Chayefsky did not do this on his own accord. Notice how quickly the camera is on her and there's already an usher there to guide her to the stage. The director sure knew where she was sitting and had a camera ready to cut to her. (And by the way, you may notice that when she's led down the aisle, she passes our old pal, Pat McCormick and also Jack Valenti.) Here's that clip…
