Jack Carson (October 27 1910 - January 2 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 which spanned the 30's, 40s and 50s. Primarily employed for comic relief, his work in Cat on a Hot Tin Roof 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 trade mark was the wisecracking know it all who eventually and typically was undone by his own over self-confidence.

When Jack Carson arrived in Hollywood in 1937, he found work at RKO as an extra. After a few years he developed into a popular character actor who would be seen in a large number of comedies, musicals and a few westerns. Not happy with the direction his career was heading, he went to Warner Brothers in 1941, where the quality of his supporting roles improved. It also did not hurt to be in films that starred James Cagney, such as Strawberry Blonde, The (1941) and Bride Came C.O.D., The (1941). After three years he starred with Jane Wyman in Make Your Own Bed (1944) and again in Doughgirls, The (1944). Jack would play the nice guy with the heart of gold who was still a nice guy even when he was angry. He would take the double take and the quizzical look to a higher level, but he could also act in dramas. He provided a good portrayal of Albert in Hard Way, The (1943) and was acclaimed for his performance in Mildred Pierce (1945). However, it was comedies that provided most of his work. He teamed up with his old friend Dennis Morgan (I) for several films in the tradition of Bob Hope (I) and Bing Crosby. It was in the 1940s that Jack would become popular as a wisecracking comedian on radio. This would lead him to TV in the 1950s, where he was one of the hosts on "Ford Star Revue" (1950), which ran until 1952. He would also help host "U.S. Royal Showcase, The" (1952). He would appear on a number of shows during the 1950s, one of his most remembered being an episode of "Twilight Zone, The" (1959) where he was a somewhat underhanded used-car salesman who came into possession of an old Model A Ford that was "haunted" in that whoever owned it had to tell the truth, whether he wanted to or not. Although his movie career slowed in the 1950s, he still appeared in a number of prestige pictures, such as Star Is Born, A (1954) with Judy Garland (I), Tarnished Angels, The (1958) with Rock Hudson and Cat on a Hot Tin Roof (1958) with Paul Newman (I).
