John Wayne, who had missed the previous year's ceremony because he was undergoing heart valve replacement surgery, accepted an invitation from his friend Bob Hope to show up for this one and present the Best Picture Oscar. It would be his final public appearance, as he died from stomach cancer two months later.
For the first time, all five nominated songs are performed by the singers who originally performed them in their respective films.
Although Johnny Carson ultimately proved a popular Oscar host, there was some initial criticism of his selection since he had only made one movie, the 1964 high-budget failure Em Busca do Amor (1964). He took the criticism lightly and joked about his motion picture debut (and farewell) on this and several subsequent Oscar broadcasts for which he was host.
Laurence Olivier received and honorary Oscar for his body of work. This was the first time he attended the ceremony since being nominated for O Morro dos Ventos Uivantes (1939) in 1939.
After the ceremony, honorary recipient Walter Lantz returned to his car only to find that he had been pick pocketed.
