(AP Photo/Harold Filan, File)NEW YORK Carl Reiner, who died Monday at 98, was the rare untortured genius of comedy, his career a story of laughter and camaraderie, of innovation and triumph and affection. Reiner died of natural causes at his Beverly Hills, California home, assistant Judy Nagy said. But CBS executives worried that Reiner would make Petrie seem too Jewish, so Van Dyke was cast instead. First lady Michelle Obama once joked that she preferred watching Dick Van Dyke to viewing her husbands debates. Reiner was the father of actor-director Rob Reiner, who starred as Archie Bunkers son-in-law on All in the Family and directed When Harry Met Sally... Rob Reiner said in a tweet Tuesday that his heart is hurting.
