Keye Luke (1904-1991), the Chinese-American actor whose Hollywood career spanned seven decades, made his screen debut in an uncredited supporting role in The Painted Veil (1934), but his big break came when he was cast as Lee Chan, detective Charlie Chan’s “Number One Son,” at Fox (soon to become Twentieth Century-Fox). The Chan series, starring Warner Oland, had begun several years earlier, but really hit its stride when Luke stepped in as a sleuthing sidekick and youthful comic foil for Oland. Both are seen below in Charlie Chan on Broadway (1937).
