It Came from Outer Space (1953)

A perfectly devoted 1950s couple have a romantic moment shattered when something fiery from space lights up their sky and crashes in the desert. After an investigation the hero concludes that it wasn't just a regular meteor.
It's typical of 1950s alien invasion movies in many ways, but in at least one significant way it's atypical. I can't say more than that for fear of spoilers. The dialogue is a step up, too, because it was based on an original screenplay by Ray Bradbury; the main character (Richard Carlson) as written retains recognisable elements of the author's way of seeing the world.
The music is fantastic, frequently dramatic, eerie and spacey all at once.

I suspect some of the perspectives used were to benefit the awful anaglyph 3D version, but thankfully they work just fine in the standard 2D version.
