Scourby first appeared on screen opposite Glenn Ford in Affair in Trinidad (Columbia, 1952) and The Big Heat (Columbia, 1953). He appeared again with Glenn Ford in Ransom! (MGM, 1956), later to be remade with Mel Gibson and Gary Sinise. Scourby played Dr. Mikhail Andrassy in The Shaggy Dog (1959). "None of the pictures I've done have been really important or very good", Scourby later said, "with the exception—and it is debatable—of Giant (Warner Brothers, 1956)". In the film version of Edna Ferber's novel Scourby played Polo, the old Mexican ranch foreman. He later had roles in The Big Fisherman (Buena Vista, 1959), Seven Thieves (1960), The Devil at 4 O'Clock (1961) and The Executioner (1970). During these extremely busy years, Scourby, who had been living with his wife and child in an apartment near Columbia University in New York City, bought a home in Beverly Hills, California. Calls for Scourby to work in New York, however, soon made the Beverly Hills residence as much a commutation point as a home.
