How come astronauts in sci fi movies wear unrealistic space suits that WOULD NOT protect them from space?

Cephalopod molluscs are known to display a high degree of intelligence, including spatial learning, communication, cooperative hunting techniques and even tool use ( https://en.wikipedia.org/wiki/Cephalopod... ). Alien molluscs (assuming there are such things - there are good reasons to think that parallel evolution in species of separate planetary origin may not occur) could combine both gastropod and cephalopod characteristics, and could conceivably evolve higher intelligence. If so, then there's no reason why they couldn't design space suits to fit their anatomical requirements.

Response to your update: Gastropods move by a series of transverse waves of contractions of the surface of their foot. I can imagine that they might develop a fabric made up of elastic cells which could be made to adhere internally to the surface of their foot, transferring the waves to the outside of the fabric. Alternatively, a stacked arrangement of revolving track, like two tank tracks, one on top of the other (to prevent the direction of movement being reversed), could transfer the movement of the foot to the outside.

Assuming first they evolved limbs in order to be tool users, they would probably use those for getting around in the zero gravity of space, like we use our hands. On alien worlds they would probably need some other type of artificial locomotion since they would hardly be able to lay slime trails from within a space suit.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
