There’s something quixotic about Francis. His world is inhabited by improbable vegetarian Texan zombies on Mexican mushrooms, all thumbs and two left feet. They build those head-nodding toys for feet-shuffling kids. Terry Gilliam is their leader. He’s wearing those red & blue cardboard glasses we were told were 3d when we were kids. He’s hammered on cough syrup. He says he’s making a remake of A Fistful of Dollars. But he’s only got a Polaroid.
