Wilbur Mack (born George Frear Runyon,[1] July 29, 1873 – March 13, 1964) was an American film actor and early vaudeville performer from the 1920s through the 1960s.

Mack was born and raised in Binghamton, New York, and began acting professionally when he joined a repertory theatre when he was 16.

[citation needed] In addition to performing, Mack wrote dialogue for skits and words and music for songs in their vaudeville shows.

[3] With wife Gertrude, he also wrote and performed in a Vitaphone romantic comedy pantomime An Everyday Occurrence (1928).

Mack made a smooth transition to talking films, but despite racking up an impressive number of appearances had less success finding lead or even featured roles.
