10 Terrifying Horror Movies You’ve Probably Never Seen

Legendary director Robert Altman's one and only entry into the horror canon -- and the folk horror canon at that -- is, quite frankly, scary as hell. Unfortunately for horror fans, it's also one of his most overlooked titles, receiving none of the fanfare or regular popularity boosts of his main body of work.

Set in a countryside that feels British but is (by design) neither easily identifiable as UK-, continental- nor USA-based, Images follows Cathryn (Susannah York), a children’s author with a growing case of lifelike hallucinations. Shacked up in a country house while she works on her current book, Cathryn is plagued by visions of violence and sinister doppelgangers, all of which conspire to tip her over the edge.

Abandoning typical Altman hallmarks and tropes -- sprawling casts, roaming cameras, rambling storylines -- the director focuses in on this one woman with spectacular clarity. And it is in this isolation that we find the real dread of Images. Lacking a secondary perspective, and with little information pertaining to Cathryn's real-life, past or present, we as an audience are as susceptible as she to the unreal.

Culminating in a perplexing and (again, quite intentional) Bergman-esque meeting of person, place and psyche, Images is a slow-burn whose many terrors are worth the wait.
