Does anyone know some great 50's or 60's horror/scifi films?

No, I have never been able to sit through one without bursting into laughter. I believe that they used to scare the girls though.

The Thing From Another World
The Beast from 20,000 Fathoms
Village of the Damned
Creature from the Black Lagoon
The Little Shop of Horrors
Them!
Day the World Ended
The Last Man on Earth
Invasion of the Body Snatchers
The Curse of Frankenstein
The Blob
The Fly
The Tingler

All of these are considered horror and sci-fi.

Forbidden Planet (1956).

In Britain from the mid 50’s right through to the seventies Hammer Horrors produced many classic movies.Dracula,Frankenstein,Werewolf to name a few.Legends of the cinema started out here, Peter Cushing & Christopher Lee made their name in such movies.I wouldn’t say they were great movies but well worth a watch.

Yeah, “The Blob”!!! And definitely “Creature from the Black Lagoon.” And just about anything with Bela Lugosi or Lon Cheney (Jr.or Sr.) And don’t forget “The Spider.”

I remember a young Steve Mcqueen making his debut in The Blob.I hasten to add well before my time. I just recall hearing about it okay!!

Attack of the 50 Foot Woman.

When I first saw the marquee for this movie it looked like this: Attack Of The 50FT Woman.

As we were driving by it looked like it said, Attack of the SOFT Woman. :-p

Quatermass and the Pit….. awesome movie!

The Day the Earth Stood Still 1951
Les Diaboliques 1953
Invasion of the Body Snatchers 1956
The Trollenberg Terror 1958
The Birds 1963
The Haunting 1963
Repulsion 1965
Night of the Living Dead 1968
Rosemary’s Baby 1968

Many of these lean more towards horror than sci-fi.

Killer Tomatoes will have you sweating in your seat.

Anything by Lon Chaney jr. is classic scary stuff and a great place to start.

The Haunting (1963) is THE best horror movie ever. I’m not even kidding. Other recommendations that haven’t been mentioned yet:

- House of Wax (1953)
– The Bad Seed (1956)
– House on Haunted Hill (1958)
– Psycho (1960)
– 13 Ghosts (1960)

And don’t forget that incredible classic, Attack of the Killer Tomatoes! : D

THE TOXIC AVENGER

cult classic
:)

The Birds for sure!

If you’re looking for Schlock:
The Beginning Of The End (with the climatic ending of cockroaches climbing a picture of a building).
Robot Monster (One of the 5 worst movies ever.)
The Amazing Collossal Man and it’s sequel Collossal Beast. Used to be my favorite films.
Son Of Godzilla
The Horror of Party Beach

If you are looking for great 50’s and 60’s SciFi and horror:
The Day The Earth Stood Still
Psycho
