I couldn't actually think of a radical movie, not off the top of my head. That's why I asked others what examples might be. I thought about it some more, and a few popped into my head: Norma Rae, Reds, Matewan, Modern Times, Metropolis. Films that appeal to a striving u.s. progressivism: Working Girl -- if you count the subtle criticism of the striving American dreamer at the end of the film when Nichols pans out to reveal that she's still just another worker bee -- Wall Street for hokey romanticization of manual labor as superior to "intellectual" labor, and hokey romanticization of the needs for ethics to temper greed, as well as and Good Will Hunting for hokey romanticization of manual laborers.
