From Wikipedia
Mitchell Lewis (June 26, 1880 – August 24, 1956) was an
American film actor whose career spanned both the silent and sound film eras.
He appeared in more than 175 films between 1914 and 1956, although many of the
roles in his later films were uncredited. During the silent era he played
supporting roles, such as Sheihk Idrim in 1925's Ben Hur, but his career would
have his roles diminish to small roles like the Captain of the Winkie Guards in
The Wizard of Oz (uncredited). His last film was The Fastest Gun Alive,
starring Glenn Ford and Broderick Crawford, which was released shortly before
Lewis' death in 1956.
