Ettore Vittorio Sarno (1880-1953) was an Italian-born actor known to have worked for New York-based film companies from around 1912. His first feature film is thought to have been Under the Gaslight (1914).
Sarno appeared in at least 200 features and shorts, mostly credited roles during the sound era, but more often uncredited after 1929, when he was largely restricted to ‘ethnic’ parts. He can be seen in King of Kings (1927), Lucky Star (1929), Wee Willie Winkie (1937), The Hunchback of Notre Dame (1939), Cloak and Dagger (1946) and The Egg and I (1947).
Sarno was a Mexican waiter in MGM’s Going Hollywood and the Gypsy leader at the beginning of Lubitsch’s The Merry Widow. IMDb also suggests he appeared in Balalaika, which seems likely given its setting.
