Lewis Lord Russell was an American actor of the 1930s, 1940s and 1950s who starred in a number of vaudeville shows, Broadway dramas and Hollywood films, including the Academy Award winning The Lost Weekend (1945) and the Marx Brothers film, A Night in Casablanca (1946).

The Lost Weekend is a 1945 American drama film noir directed by Billy Wilder, and starring Ray Milland and Jane Wyman. It was based on Charles R. Jackson's 1944 novel of the same name about an alcoholic writer. The film was nominated for seven Academy Awards and won four: Best Picture, Best Director, Best Actor, and Best Adapted Screenplay. It also shared the Grand Prix at the first Cannes Film Festival, making it one of only three films—the other two being Marty (1955) and Parasite (2019)—to win both the Academy Award for Best Picture and the highest award at Cannes.
