Apologies for lack of details in advance. I'm am trying to place a movie that I saw a photo of in a Sci-Fi documentary book somewhere between 1979 to 1981. There is a dwarf sized humanoid creature that looks similar to the Creature from the Black Lagoon. It is surrounded by men in I think radiation suits all armed with long rods, that I think glow at the pointy end. My impression was that it was a 50s or 60s movie but so far all my searches have failed. Thanks in advance.
I think it's "20 Million Miles to Earth". The monster, the Ymir, was brought back from Venus. It starts out very small, but it keeps growing and growing.
