Wonder Bar is a 1934 pre-code movie adaptation of a Broadway musical of the same name directed by Lloyd Bacon with musical numbers created by Busby Berkeley. It stars Al Jolson, Kay Francis, Dolores del Río, Ricardo Cortez, Dick Powell, Guy Kibbee, Ruth Donnelly, Hugh Herbert, Louise Fazenda, Fifi D'Orsay, Merna Kennedy, Henry O'Neill, Robert Barrat, Henry Kolker, and Spencer Charters in the main roles. For its time, Wonder Bar was considered risqué, barely passing the censors at the Hays Office.
