>>Sorry, I stand corrected. I don’t know why I thought it was made in the 30s, Maybe because I’ve only seen the movie in b&w.<<

As far as I know, that film MAN FROM PLANET X is all B&W.
No color versions.

Maybe one factor that got you thinking 1930’s is this alien did not arrive in a flying saucer but a diving bell spaceship. The alien's spacesuit is also like an old diving suit.
They give a pseudo-scientific explanation for this in the movie.

Probably the setting and the cars in the movie got me thinking it was older. And the diving bell with a point on top probably helped. I actually liked the movie It was entertaining.
