Yes, descriptive I know.
I have vague memories of my dad and brother watching a movie, or possibly a TV show in the mid to late 1980’s. An astronaut is on a space-walk and something unexpected happens where he is exposed to cosmic rays or some other weirdness.
He is brought back to Earth and shenanigans ensue. I left the room at this point because it had scared me, I fully expect to find it was about as frightening as Bambi, but I was pretty young.
