Arriving in Los Angeles in 1916, Finlayson found film work at
L-KO and
Thomas H. Ince's studio. and appeared in numerous Sennett comedies, including with the
Keystone Cops. The promotional newspaper article for the 1920 premiere of Sennett's
Down on the Farm refers to Finlayson as "legitimate and screen player of international celebrity", and of his performance says: "The villain in the case—a sort of cross between a Turkish
Don Juan and a 'loan shark'—is played with rare power and comic results of seriousness by James Finlayson". Finlayson sent to Scotland for his close friend
Andy Clyde, urging him to join him at the Sennett studio. Clyde arrived in 1922 and became a Sennett fixture as a versatile character actor. Finlayson, however, did not establish himself as star material, and left Sennett's employ later that year.
Hal Roach Studios Finlayson was hired almost immediately by Sennett's rival,
Hal Roach, who gave him supporting roles in his studio's
Snub Pollard and
Stan Laurel comedies. With Roach's biggest short-subject star
Harold Lloyd moving on to features, Roach tried to start new series with
Charley Chase (successfully) and Finlayson (unsuccessfully). The next step came in 1927 when Roach's
All-Star Comedy series gave Finlayson equal billing with up-and-coming co-stars
Stan Laurel and
Oliver Hardy, comedian
Edna Marion, and others; some studio publicity even referred to Finlayson, Hardy, and Laurel as a "famous comedy trio." But Roach staff producer and future
Academy Award director
Leo McCarey recognized the great potential of a Laurel-and-Hardy pairing and began developing their characters and expanding their roles. By the autumn of 1928, Laurel and Hardy had their own starring series while the
All-Star Comedy series soldiered on with other comedians. Nonetheless, Finlayson was still "considered by many to be an indispensable part of the Laurel & Hardy team." Altogether, Finlayson had roles in 33
Laurel and Hardy films, usually as a villain or an antagonist, in such films as
Big Business (1929) and
Way Out West (1937). He also starred alongside Laurel in 19 films, and Hardy in five, before Laurel and Hardy were teamed. He appeared in dozens of Roach films with
Charley Chase,
Glenn Tryon,
Snub Pollard and
Ben Turpin, and in several
Our Gang shorts, including
Mush and Milk, in which he and
Spanky McFarland match wits in a comically adversarial phone conversation. Finlayson later played uncredited bit parts in films such as
Foreign Correspondent (1940),
To Be or Not to Be (1942), and
Royal Wedding (1951). He was often called on for silent-comedy reunions like
Hollywood Cavalcade (1939) and
The Perils of Pauline (1947). ==Personal life and death==
