Kitty Carlisle (1910-2007) was an American actress, singer, and socialite, known for her elegance and soprano voice. Her film career flourished in the 1930s, where she distinguished herself in starring or co-starring roles in musical comedies.

She debuted in *Murder at the Vanities* (1934), but she is best remembered for her role as Rosa Castaldi alongside the Marx Brothers in *A Night at the Opera* (1935). In these films, Carlisle often embodied the refined ingenue or sophisticated woman, with an innate grace and vocal abilities that allowed her to perform opera arias and popular songs. While she had a more extensive career in theater, opera, and television, her contributions to cinema remain iconic for the era.
