Caravan killers

Here’s a fun diversion for all the family: how many ‘high-concept’ film ideas can you think of in a single minute? These are the films with premises that can be summed up — and pitched to expectant, impatient Hollywood producers — in only a few words. ‘Jaws in Space’, say, or ‘Arnie versus Hitler’. Get started now, and you could soon have the studios drooling a path to your door, eager to turn your aphorisms into easily marketable products. Red carpets and golden paycheques await.

I mention this because, at first glance, it seems as if Ben Wheatley’s Sightseers is the result of a similar game. Its plot concerns a youngish couple going on a camping holiday around Britain, and killing people along the way — in other words, ‘Bonnie and Clyde in a caravan’. It smells like something we’ve encountered before, only with a slight twist to keep it fresh.
