Here is a list of some badass Horror films:

I own everyone of these films on dvd, laserdisc or VHS. I guess you could call me a cinephile

You will see a lot of Christopher Lee and Peter Cushing films, because they were Horror film titans (for the younger audience, Christopher Lee plays Saruman the White in Lord of the Rings and Hobbit films and Count Dooku in Star Wars, and Peter Cushing played in the original Star Wars as Moff Tarkin, but those roles suck in comparison of their early films)


The Thing 1951
The Thing 1982 (EPIC)
The Wicker Man 1973 (Christopher Lee version, skip Nick Cage version)
The Skull 1965 (Christopher Lee and Peter Cushing)
I, MONSTER 1971 (Christopher Lee and Peter Cushing and one of the best adaptations of DR Jekyll and Hyde films ever)
The Creeping Flesh 1973 (Chris Lee and Peter Cushing)
The Night Stalker 1972 and The Night Strangler 1973 (about a hot shot reporter that investigates supernatural stories, and there was a series after the 2 films called Kolchak the Night Stalker, and they all have the same character, which is pretty amazing)
The Devil Rides Out 1968 (christopher Lee and Donald Pleasance)
Witchfinder General 1968 (Vincent Price)
Don't Look Now 1973 (Donald Sutherland, Julie Christie)
The Abominable DR Phibes 1971 (vincent price)
As Above So Below 2014 (not amazing, but worth watching)
Island Of Lost Souls 1932 (Bela Lugosi, Charles Laughton) This film wasn't considered a B film when it was made, which was very rare for any horror film to be taken seriously at the time

and I will write some more later, getting sleepy. I'm out
