Comedian George Carlin died of heart failure in a Santa Monica hospital yesterday evening. He’d entered the hospital earlier that day, complaining of chest pains. Carlin had a history of heart problems, and had previously survived a heart attack. He also fought a longtime battle with drug addiction. Carlin had been notified earlier this year that he was to receive the John F. Kennedy Center’s coveted Mark Twain Prize for American Humor this November. His last appearance in a film was as Ben Affleck’s father in Jersey Girl and he also provided the voice for “Fillmore” in the animated film Cars. The Grammy-award winning comedian leaves behind his wife, Sally, and daughter, Kelly.
