Carol Burnett was riding the crest of CBS success with her Saturday night variety show when she bravely challenged herself by taking on the lead film role in a drama written by the man who wrote Casablanca. Her 1972 co-star was Walter Matthau, very popular with moviegoers audiences at that time. In Pete 'n' Tillie, her character says "Honeymoon's over. It's time to get married." Not your typical middle-aged couple.
