SF film recommendations

I’d like recommendations on B&W SF films, set in the American desert, anything with an extended night time scene would be nice.

I’ve already picked up a copy of Them.

I was ready to post before reading your OP. I’ll check back for the answers you’re looking for.

Not a film but there is a Twilight Zone episode about crashed astronauts in the desert also another TZ “The Lonely” is SF in an off world desert.

Tarantula.

Think I’ve got that first one floating around somewhere, I’ll check for the second, thanks.

Besides those mentioned, try

It Came from Outer Space (which is axailable in 3D!)
and the BAdFilms

**Killers from Space

Robot Monster

The Beast of Yucca Flats
Attack of the 50 Foot Woman** (lots of night scenes in this one)
