This other major work by the writer of the English folk horror landmark The Blood on Satan’s Claw (1971), Robert Wynne-Simmons, is more restrained than that unsettlingly erotic, dreadful conjuring of rustic demons and collective evil. He argues on his sole directorial feature’s Blu-ray debut that it isn’t folk horror at all, simply an Irish folk tale in pre-Famine days “when magic had a value”.

You may have heard the phrase “elevated horror” being used to describe horror films that lean more toward arthouse cinema, favouring tension and psychological turmoil over jump-scares and gore.

In his first of a series of meditations on the sickness that was consuming him, John Donne reflected upon the special kind of paranoia that attends the ill individual. Each person is, by virtue of "being a little world", supremely conscious of a change in the atmosphere.

No film tackles the knotty topic of inherited mental illness with as much gleeful abandon as Smile. Mental health has been a popular subtext in contemporary horror for the past decade, but Parker Finn's Smile felt refreshing in how unsubtle it was. The premise was a curse that drives you mad with violent hallucinations that eventually force you to kill yourself, passing the curse on to whoever witnesses your death.

A boy’s dead friend scratching at his first-floor window, Nosferatu-like vampire Barlow rearing up with heart attack shock…The Texas Chain Saw Massacre director Tobe Hooper’s 1979 TV take on Stephen King’s Salem’s Lot scared a teen generation out of their skins.

This new film exists first as a failed franchise equation, adding Conjuring Universe producer James Wan to IT screenwriter Gary Dauberman as writer-director (he also wrote The Conjuring’s Annabelle series), but suffering heavy cuts prior to this much delayed release.

Time-travel is a trap in debutante Michael Felker’s tender sf two-hander, whose title’s grim irony becomes gradually apparent.

If you like a body-horror movie to retain a semblance of logic in its plot line, then The Substance – grotesque, gory and finally insubstantial – may not be for you.

Sometimes love never dies and the dead never rot. A lot of water has flowed down the River Styx since Tim Burton’s first Beetlejuice film in 1988, but the bones of the original have held up surprisingly well, the madcap morbid spoof outliving many of its peers from the “high concept” era.

Blame the high cost of city housing, or killer smog. What else can explain a bright young couple’s move from 1970s Leeds to Starve Acre, an isolated, near-derelict farm in rural Yorkshire that has to be the spookiest back-to-the-land setting since The Wicker Man.

Strange noises fill the crisp nighttime air in a small Alpine village: Avian shrieks and some wild beast a-rustling in the hedgerows – or are those the screams of a desperate woman?

Into the strange, scary, funny world of Cuckoo comes a British-American family that has upped sticks and packed the entire household – dad, stepmom, and little daughter – to rural Bavaria, where the father will be renovating the local spa-resort.
