One of my fave YouTube personalities Peter Petraitis (he does Edie Beale, Jackie O, Dietrich, Loretta Young - among others) really out did himself when he was inspired to create this vid.
I found this salute to MM's final film performance in The Misfits to be a real hoot. He certainly captures frail Marilyn dancing on the edge of oblivion. I also find these "out takes" far more entertaining than the creepy elegy of that actual self-indulgent film and its neurotics-on-parade.
