Slim Summerville (born George Joseph Somerville; July 10, 1892 – January 5, 1946) was an American film actor and director best known for his work in comedies.

[2] In Canada, in Chatham, Ontario, he lived with his English grandparents and obtained his first job there, working as a messenger for the Canadian Pacific Telegraphs.

Sennett immediately hired him for $3.50 per day to perform in bit parts, his first being in the role of a "Keystone Cop" in the short Hoffmeyer's Legacy.

Occasionally, Summerville played in dramatic films, such as All Quiet on the Western Front (1930) and Jesse James (1939), but he was most successful in comedies, including several with ZaSu Pitts.

He also performed with child star Shirley Temple in the musical-comedy dramas Captain January (1936) and Rebecca of Sunnybrook Farm (1938).
