The 79-year-old told The Observer that the "self-fulfilment" of work keeps him happy and healthy in old age.
The actor has so far enjoyed a career spanning five decades, having starred in classics such as The Godfather and Apocalypse Now. He has also scooped an Academy Award, two Emmy Awards and four Golden Globes along the way.
Duvall said: "Retiring is like the end of the world, especially in this business. You need self-fulfilment.
"Why retire? An athlete retires at 35, 40 at the most; an actor doesn't have to retire till he's 80 or whatever. A lot of people, when they retire, it's over, they're gone... men quicker than women."
> Robert Duvall linked to 'Don Quixote'
