Can't find a pic - anywhere - but Ricardo Montalban had horrible fake Japanese makeup in the 1957 Sayonara (which was actually a pretty cutting-edge film treatment of interracial romance, for its day, considering that movie censorship usually vetoed any treatment of the subject.)

They used an Asian actress for the Asian woman/American G.I. romance, but for the Asian man/American woman romance, they had to use a non-Asian male actor. Was it just too gruesome in that era to have an Asian actor making cinema love to a white woman?
