James Finlayson, Scottish-American actor (b. 1887)
James Henderson Finlayson (27 August 1887 – 9 October 1953) was a Scottish-American actor who worked in both silent and sound comedies. Bald, with a fake moustache, Finlayson had many trademark comic mannerisms and is known for his squinting, outraged, "double take and fade away" head reaction, and characteristic expression "d'ooooooh", and as the best remembered comic foil of Laurel and Hardy.

Finlayson was known by a variety of nicknames. According to Laurel and Hardy scholar Randy Skretvedt, he "called himself Jimmy, was known around the lot as Jim and is usually referred to today as 'Fin'" – perhaps because he played a character called Fin in Our Relations and one named Mickey Finn in Way Out West, or most likely, just as a truncated version of his surname.
