Actor Paul Winfield, who played civil rights leader Martin Luther King Jr on television and earned an Oscar nomination for his role as a share-cropping father in Sounder, has died at age 62, associates say. Winfield, who had long battled weight problems and suffered a stroke in recent months, died of a heart attack on Sunday night at a Los Angeles hospital, a representative for the actor said. The tall, deep-voiced actor’s last role was a cameo appearance in an ABC television movie remake last year of Sounder. Simpsons fans will remember Winfield by his role of Lucious Sweet in the episode ‘The Homer They Fall’, and a small cameo in the episode ‘The Trouble With Trillions,’ where he appeared as Drederick Tatum’s manager.
