A Grand Hotel derivation set in a major metropolitan train terminal, Union Depot features most of the reliable Warner Bros. stock company. Douglas Fairbanks Jr. stars as a slick thief; Joan Blondell costars as a stranded chorus girl; Alan Hale Sr. is featured as a phony baron absconding with company funds; and Frank McHugh does his drunk act. Other arrivals and departures include Guy Kibbee, David Landau, and George Rosener (as a sexual deviate stalking Ms. Blondell!) The huge depot set built for this film may seem like an unnecessary expenditure, but the set would come in handy for future, less costly Warners endeavors. The British title for Union Depot was Gentleman for a Day, reflecting the crooked Fairbanks' good-guy turnaround at the end of the film.
