Thanks! I'm looking at his complete filmography here:
Robert Greenwald
In addition to being a lefty, he's produced/directed some really awful films:
Xanadu (1980)
I'm still recovering from seeing that one. . .
The ACLU is funding his upcoming "Unconstitutional." I guess that one will be about the wave of anti-Muslim hate crimes and library list snooping caused by the Patriot Act.
