The Wave (15, 107 mins)
Based on real-life events (as the corny voiceover would have it), this is a disturbing fable about how easily fascism can take root.
A teacher gives a class on the theme of autocracy, but the resulting experiment takes on a life of its own, ultimately and inevitably ending in tragedy.
With echoes of another German film, Das Experiment, based on the Stanford Experiment of 1971 (in which a mock-up of prison conditions led to some genuinely savage and sadistic behaviour), this promises to be a salutary and sobering tale.
