Tim Robbins' CRADLE WILL ROCK (1999) is the latest movie I've seen! It was actually for a final paper at college...Although I had to watch it three times, I really enjoyed it. .
Two things I loved about it: 1. I hadn't known about Rivera's rejected painting on the Rockefeller Center's mural. 2. PJ Harvey's version of the song
NICKEL UNDER THE FOOT which is played in the credits is really nice!

For those who haven't seen it yet, Diego Rivera was invited by Nelson Rockefeller to paint a mural at the hallway of the Rockefeller center in the 1930s.However, differently from what he presented in the sketches, he painted - from the theme MAN AT THE CROSSROADS given by Rockefeller himself - a revolutionary mural with Lenin leading his red revolution, Hitler's statue losing its head, and also syphilis cells floating over the decadent rich people. It had - of course - to be destroyed. It could never fit an America soaked in the Great Depression, and surrounded by an extreme political atmosphere which considered anyone who had other ideals than those stablished by the government as reds. I don't know if Rivera did it on purpose...that would be so ironic!
That's a great movie, especially for those who also appreciate Orson Welles' work.
