*Jason Robards also beat out Alec Guinness for Star Wars, the only acting nom given to anyone from the Star Wars series. John Williams won for Original Score, though.
Woody Allen (Annie Hall) beat out George Lucas for Best Director & for Original Screenplay, and ironically, after Chavefsky sadi what he said, he had to present the Adapted Scrrenplay award to Julia. Earlier Jane Fonda, who was the lead in Julia, had lost the Best Actress award to Dianne Keaton.
Also of note: this was the year that "You Light Up My Life" won for Best Song. The absolute nadir of this Oscar.
And Richard Dreyfuss became the first guy under the age of 30 to receive the Best Actor award (he was 29).
