Along with DANTE'S INFERNO and THE MERRY WIDOW also made in 1934, I think this film is the reason the censorship Hays code was rigidly enforced in Hollywood for the next 30 years. Deleriously vulgar and immoral in every scene, all set in a sensational nightclub for all ages and kinky tastes, each leering winking and squabbling, all set to foxtrots and waltzes re-imagined by Busby Berkeley and climaxing with the most hilariously offensive musical number of all time: Going To heaven On A Mule. There's no point explaining it or any other of the screwy dance numbers...including the leather clad S&M themed whipping (and murder) tango by "Inez and Harry"...complete with loud cracks of the whip across the gorgeous face of the awesomely beautiful Delores Del Rio. Someone at Warners must have decided to create a shopping list of production possibilities directly from the planned Hays code of banned themes. It just does not stop being deliberately immoral vulgar and hilariously rude for all of its 88 minutes. I loved all 189 minutes of it because I kept re winding so many bits over and over just to gasp between laughs at the blatant unstoppable cheerfulness of it's violations. All in the most glamorous setting and style imaginable. The orchestral score is excellent - and I have an LP from the 70s with GO INTO YOUR DANCE on the other side. It is created directly from the soundtrack so there is plenty of dialog as well. WONDERBAR is CABARET 1934 for real. Wait 'till you see the epic musical sequence called Don't Say Goodnight where a squadron of negligee clad showgirls dance around massive moving 'pillars' that have big veiny patterns weaving down from the top. That is in between floating past the camera, lit from behind so we can see how sheer their garments are. The scene where two turkey -like old dames ditch their husbands and together pick up the one gigolo (planning a threesome) is a screamer...he clinches the job with the incestuous note "You remind me of my mother" to which they very happily go for him.... and this is all just starters! On top of all this is Al Jolson leering and bellowing, all lustful and creepy... not too much a stretch for Joel Grey in 1972 singing Wilkommen and getting an Oscar! Find WONDERBAR and show it to everyone you know! Colossal and bent as all hell... to music. Read the other comments on this site for the story and viewer outrage. Haha!
