George Lucas’s feature-length 1971 expansion of his student short is a strange beginning for one of the most consistently crowd-pleasing careers in recent film history. Robert Duvall is a reluctant zombie trying to escape a repressive society of the future, which is resourcefully evoked through location shooting in underground garages and San Francisco’s subway system. Muddled and hopelessly artsy, but at least Lucas got it out of his system early on.
