Casanova Brown is a 1944 American comedy romantic film directed by Sam Wood, written by Nunnally Johnson, and starring Gary Cooper, Teresa Wright, and Frank Morgan.

The film had its world premiere in western France after the Allies had liberated those territories following the D-Day Invasion.

Arriving in a small town Rossmore, Illinois by train, college professor Casanova Brown is met by his socialite girlfriend Madge Ferris and tells her not to bring up his trip to New York, where he was trying, unsuccessfully, to publish a book about the notorious 18th-century womanizer, Casanova.

Isabel confesses to Dr. Zernecke that the adoption was just a ploy to bring Cas to the hospital and discover how he really felt about her and the baby in wanting him back in her life.

The film was nominated for three Academy Awards: for Best Score (Arthur Lange), Best Sound, Recording (Thomas T. Moulton), and Best Art Direction (Perry Ferguson, Julia Heron).
