Robert Duvall, the Oscar-winning actor whose classic roles included the wily confidant of the first two “Godfather” movies, had died at age 95. He first gained notice for a small part as the reclusive neighbor in “To Kill a Mockingbird.” He won an Academy Award as best actor for portraying the over-the-hill country music singer in the 1983 film “Tender Mercies.” He also won four Golden Globes, including one for playing the philosophical cattle-drive boss in the 1989 miniseries “Lonesome Dove,” a role he often cited as his favorite.
