Atmospheric British horror/mystery of the 70s and 80s

They are TV movies but the stuff under the Ghost Story for Christmas strand from that period would be in similar space.

If you like The Stone Tape, think Nigel Kneale did some TV stuff for ITV you should check out. He also adapted 1989 The Woman in Black.

Another anthology

Straw Dogs is one of my favorites from that period. Think it has that same vibe you're talking about.

If you haven't already seen it, do make the effort to seek out 'The Asphyx' (1972) starring Robert Powell. One of those films that never gets a mention.. not even on cult film lists. However, once seen it's not easily forgotten. It most definitely ticks all of your above requirements.

This copy is very acceptable if you're unable to source better.

Agree with you on that. Would add that this film should be replayed on mainstream media to remind those keyboard warriors who suggest that nuking a few cities in Russia would quickly end the invasion of Ukraine and that we would all live happily afterwards.

Has anyone suggested that?
People have well understood the implication nuclear war for well over 60 years at this stage. Not sure a movie is necessary

Fragment of Fear (1970) with David Hemmings and Arthur Lowe

I Start Counting (1970) - Jenny Agutter school thriller.

Unman, Wittering and Zigo (1971) AND Child's Play (1972)

Something to Hide (1972) - Peter Finch, Shelley Winters, our own Colin Blakely and Harold Goldblatt, plus footage of 70s Dublin at Christmas on the telly.

Pete Walker's films

American, but The Brotherhood of Satan (1971) has that hauntological feel, and is sorely underrated. Very similar to the British Nothing but the Night (1973)

A big part of the atmosphere created in those films is thanks to the actors. Working stage actors who really learned their craft, and treated it as a craft. Rarely cast for their looks, but for their ability and effort. Something that you don't see as often now.

The Ghoul is nicely atmospheric also, as is The Vault of Horror.

Sleuth 1972 adapted from the stage play starring Laurence Olivier and Michael Caine is a great mystery thriller film creates a great atmosphere

I was born not too long before Threads was broadcast on television and the couple with the baby in it really freaked my mam out. Was a bit too close for comfort!

It's a really fantasticly depressing thing. I've watched it many many times up to the nuclear exchange part but usually stop there given how utterly depressing the second half is.

Always thought it should be mandatory viewing in secondary schools.

The Man who Haunted Himself from 1970 starring Roger Moore.

It's American but Race with the Devil (1975) is very good.

The Talking Picture encore player works in ROI, though not all films are shared on it and they've jacked up the number of intro ads. But yeah, good shout for 70s stuff, especially the Friday night "Cellar Club" stuff with an intro from onetime Hammer scream queen Caroline Munro.

Thriller is considered horror by pretty much every British horror nerd I know.

Sure, there's even an ep called Nurse will Make It Better, which predates the Omen, and even has Pat Troughton as an Irish priest who has encountered Satan before.
