This is footage of a doubles tennis match held on July 13th, 1937 to celebrate the opening of the Beverly Hills Tennis Club. The game pitted Charlie Chaplin & Fred Perry against Groucho Marx & Ellsworth Vines. Chaplin and Perry won 6-1, 9-7. Other familiar faces in the video include Paulette Goddard and Douglas Fairbanks.
This is my edit of a longer version of the footage which can be found here. I also added some music (from The Chaplin Revue/A Dog's Life).
Note Groucho's buff bod.
