Sven was completely off-base in his comment, as far as I can tell from some quick Internet research. Anna May Wong was a star of silent movies in the 1920s and it seems unlikely that she would have taken a role in a Paramount short in 1932, especially one where she portrayed a singer in a dive. "Anna May Wong: From Laundryman's Daughter to Hollywood Legend" by Graham Russell Gao Hodges would confirm this but even if you rely on the Wikipedia entry on her, "She spent the first half of the 1930s traveling between the U.S. and Europe for film and stage appearances." A look at her picture shows no resemblance to Anna Chang. According to a review on another site, Chang and Joe Wong, her co-star, were "popular Chinese vaudeville stars." That seems more plausible to me than assuming that Anna May Wong appeared in "Singapore Sue" under a pseudonym.
