In The Thin Man (1934), Romero played a villainous supporting role opposite the film's main stars William Powell and Myrna Loy. Many of Romero's films from this early period saw him cast in small character parts, such as Italian gangsters and East Indian princes. Romero had a lead role as the Pathan rebel leader, Khoda Khan, in John Ford's British Raj-era action film Wee Willie Winkie (1937) starring Shirley Temple and Victor McLaglen and The Little Princess (1939) also with Temple. He also appeared in a comic turn as a foil for Frank Sinatra and his crew in Ocean's 11 (1960) starring the Rat Pack (Sinatra, Dean Martin, Sammy Davis Jr., Peter Lawford and Joey Bishop).
