Carl Reiner was 98 when he died. I’ll never forget the hours I spent with him sitting in his Beverly Hills home in the same chair that his best friend Mel Brooks always used when he visited. Reiner was 94 on that summer afternoon when I spoke to him about his long career in television and film, his 65-year marriage to his wife Estelle and why he’d always wanted to be an Irish tenor. Then Carl Reiner burst into song. That’s all on this episode of “Now What?” which is produced with the help of Stephen Colon, Gabe Zimmer and Steve Zimmer. Audio production is by Nick Ciavatta.
