This week's new DVD & Blu-ray

Punishment Park When this film was released in 1971, the events that inspired it (such as the Kent State shootings and the Vietnam war) were still fresh in the audience's minds. When it arrived on DVD a few years back, it was the incarcerations at Guantánamo Bay that drew obvious comparisons. It's only fitting that this latest release, on Blu-ray (and DVD again) arrives soon after rioting and general unrest in Egypt, London, America and, sadly, plenty of other locations. Highly influential director Peter Watkins again uses the documentary style he developed with earlier classics The War Game and Culloden to great effect. A collection of student, arty types and suspicious-looking longhairs are paraded in front of a community tribunal (more a kangaroo court) for various crimes against society (some no more than daring to question the status quo). They are told they can have their long prison sentences commuted to freedom if they can make it across a blistering desert to an American flag while being pursued by armed police. It was largely dismissed as a rambling, paranoid fantasy at the time. Now, it's more a razor-sharp slice of speculative fiction and much of the footage is virtually impossible to differentiate from contemporary news. There may well come a time when this film isn't relevant, but it's unlikely many of us will be around to see it.
