Sightseers

Tina and Chris go on a caravanning tour of the North of England's less glamorous heritage sites, the pencil museum, the tram museum, and Chris begins killing people who irritate him, littering, condescension, owning a better caravan.

Ben Wheatley directed a script by its two stars, Alice Lowe and Steve Oram, and the tone is pitch black: the murders are sudden and matter-of-fact, and the film is really about a folie à deux between two lonely, petty people egging each other on.

It is very funny in a specifically English way, about a couple whose romance is built on shared grievance, and the caravan-park settings are filmed with real deadpan affection.

The knitwear, the National Trust gift shops, and a death by tent peg are the details people remember.

It is the most accessible of Wheatley's early films and the funniest.
