Really scary DVD

I believe it's a movie from the 50's with Judi Garland where she works in vegas and hooks up with a drunk guy who's career is failing, so she get more famous and he goes into the crapper. I only know that because I had a professor once that claimed it was an american masterpiece. I thought it was a mater-piece of crap. Put that on a double bill with Gili, your mind would melt out of your ears and out of sheer revolt your eyes would pluck themselves from their sockets to get away.
