Can't say, for sure, what was the first movie I saw. We got our first TV in 1950 and I probably saw a movie or two on TV, and maybe even a few in a theater by that time. However, I can tell you the first movie I REMEMBER seeing in a theater. It was The Thing (now known as
The Thing From Another World). It scared me to the point that, to this day, generally speaking, I do not enjoy the Science Fiction/Fantasy and Suspense/Horror genres. There are, of course, notable exceptions. I was probably 5 years old when I saw this movie.
I also remember being taken, a few years later, to the see
The Creature From The Black Lagoon. If there was any hope of enjoying the Science Fiction/Fantasy and Suspense/Horror genres after seeing The Thing, seeing The Creature From The Black Lagoon, murdered it.
