 C.W. Moss mentions, in the first scene with Buck and Blanche, that  Myrna Loy (qv) is his favorite movie star. Loy was supposedly a  favorite actress of John Dillinger (I) (qv). In fact, when he was  gunned down outside the Biograph Theater in Chicago, the film he had  just seen was _Manhattan Melodrama (1934)_ (qv), in which Loy  starred.
