Comedian and actor Richard Lewis, whose last role was in the current and final season of HBO’s Curb Your Enthusiasm, has died from a heart attack. He was 76 years old.

Lewis, who was diagnosed last April with Parkinson’s disease, said at the time that the last 3 1/2 years had been “a rocky time”, during which he had undergone four surgeries back to back and found out he had Parkinson’s disease.
