In his second cult classic film, Errol Morris introduces up to Vernon, a town in the Florida panhandle surrounded by swamps. In this forgotten corner of the American south, Morris found the quietly fascinating subjects for the follow-up to his galvanizing debut, “Gates of Heaven”: an enthusiastic turkey hunter, a bizarre priest, a worm farmer, a terse policeman and a married couple with a very specific take on the consequences of radioactivity. As ever humane yet sharply focused, Morris lets his camera subjects pontificate and perambulate the environs of this seemingly unremarkable little community. The result is a strangely philosophical work on human eccentricity that appears to have landed from outer space, instantly cementing its director’ standing as an important figure in American film.
