A renowned actor and director of the silent era, Hoyt's illustrious career on the Broadway stage began in 1905, with his entry into the acting fraternity facilitated by the recommendations of his uncle, a dramatic editor for a Cleveland tabloid. Under the guidance of theatrical producer George C. Tyler, Hoyt's early performances earned him a modest $10 per week, with the versatile actor taking on up to ten different roles. His Hollywood debut in 1916 marked the beginning of a long-term association with Universal Pictures.
Characterized by his diminutive stature, balding head, and bespectacled gaze, Hoyt's on-screen persona revolved around portraying 'little men' - mild-mannered professors, henpecked husbands, or intimidated minor officials. His signature look, perpetually befuddled and confused, became his stock-in-trade.
Throughout his 30-year career, Hoyt delivered memorable performances in various films, including The Lost World (1925),directed by his younger brother Harry O. Hoyt, where he played the role of Professor Summerlee. He also impressed audiences as the bewildered motel owner in It Happened One Night (1934) and as Mayor Tillinghast in The Great McGinty (1940).
Notably, Hoyt's screen career was marked by a significant number of uncredited roles. For his final seven years in the industry (1940-1947),he was a regular member of Preston Sturges' personal entourage of stock players at Paramount Pictures.
