From Wikipedia, the free encyclopedia. John Elmer "Jack" Carson (27 October 1910 – 2 January 1963) was a Canadian-born U.S.-based film actor. Jack Carson was one of the most popular character actors during the 'golden age of Hollywood', with a film career spanning the 1930s, '40s and '50s. Primarily employed for comic relief, his work in Mildred Pierce (1945) and Cat on a Hot Tin Roof (1958) proved he could also master dramatic material. During his career, he worked at RKO, MGM (cast opposite Myrna Loy and William Powell in Love Crazy), but most of his memorable work was at Warner Brothers. Carson's trademark was the wisecracking know it all who eventually and typically was undone by his own excessive self-confidence.
