Mack Swain

Mack Swain (born Moroni Swain, February 16, 1876 – August 25, 1935) was an early American film actor, who appeared in many of Mack Sennett's comedies at Keystone Studios, including the Keystone Cops series. He also appeared in major features by Charlie Chaplin.

In the early 1900s Swain had his own stock theater company, which performed in the western and midwestern United States.

Swain worked in vaudeville before starting in silent film at Keystone Studios under Mack Sennett. While with Keystone, he was teamed with Chester Conklin to make a series of comedy films. With Swain as "Ambrose" and Conklin as the grand mustachioed "Walrus", they performed these roles in several films including The Battle of Ambrose and Walrus and Love, Speed and Thrills, both made in 1915.

Besides these comedies, the two appeared together in a variety of other films, 26 all told, and they also appeared separately and/or together in films starring Mabel Normand, Charles Chaplin, Roscoe Arbuckle and most of the rest of the roster of Keystone players.
