Blithely amoral and thoroughly entertaining, this is not a film the British tourist board would want you to see. Directed by Ben Wheatley and written by its two leads, Steve Oram and Alice Lowe – familiar to fans of The Mighty Boosh, Garth Merenghi’s Darkplace and other offbeat, cult TV comedies – Sightseers combine banal reality, slapstick comedy and Grand Guignol theatrics to riotous effect in its tale of a caravanning holiday cum erotic odyssey descending into an ever more eyebrow raising bloodbath. If the caravan’s a rockin’, don’t come a knockin’!
