David Niven is the only person to win an Oscar at the ceremony that he himself was hosting.
He won the 1958 Best Actor Oscar for his role as Major Pollock in the melodrama Separate Tables, at his first and only Oscar nomination.
Appearing on-screen for only 23 minutes in the film, Niven’s was the briefest performance ever to win a Best Actor Oscar. By today’s standards, his role would be considered in the Best Supporting category.
In 1991, Anthony Hopkins also won the Best Actor for essentially a secondary role, in The Silence of the Lambs.
