The American Film Institute (AFI) Catalog, Feature Films, 1931-1940, reports data for this movie from a print with no end credits, and has much misinformation. Turner Classic Movies (TCM) shows the movie with end credits, extending the credited cast to 14 (from the 6 listed in the opening credits) and provides additional crew not mentioned in AFI's Catalog.
