Oscar winner Robert Duvall, a versatile actor who made lasting impressions in a range of parts from starring to supporting roles like the napalm-loving colonel of Apocalypse Now or the spectral Boo Radley in To Kill a Mockingbird, has died at age 95, his wife said in a Facebook post.

“For each of his many roles, Bob gave everything to his characters and to the truth of the human spirit they represented,” Luciana Duvall said in the post.

Duvall played forceful leaders such as Lieutenant Colonel Bull Meechum in The Great Santini and the title character in Stalin, as well as broken-down and fallen characters in Tender Mercies and The Apostle. He won awards for both types of roles.
