The Crimson City on AllMovie

Onoto (Myrna Loy) is slated to be sold to a wealthy Mandarin, but is rescued from the auction block by white fugitive from justice Gregory Kent (John Miljan). Onoto falls in love with Kent, and he with her, but this is 1928, and marriage between races is still taboo. Gallantly, Onoto forsakes Kent so that he may marry his white sweetheart Nadine Howells (Leila Hyams), then sadly disappears into the night. Asian actress Anna May Wong, who by rights should have played the leading role, is consigned to a glorified bit part.
