I've been searching for this movie for many years now. I was born in 1989 and I was under 10 years old when I watched it on TV, so I assume it's a movie from the 80s or early 90s.
I'm gonna describe TWO scenes; as I said, I was just a kid, so I can't be sure they are both from the same movie.
I remember a motorhome with some sort of group of scientists / students / explorers searching for something. And at some point, one of them was outside the trailer and the ones inside were monitoring his position with a radio and through a screen like a radar. When something gets really close to him on the screen, I remember them saying: "IT'S RIGHT THERE! IT'S RIGHT IN FRONT OF YOU." And the guy outside says: "THERE'S NOTHING HERE, I'M ALONE." Because it was in a deep forest, and all he could see was trees and leaves. I'm pretty sure it was during the day.
I remember an older man, taking a dump at one of those "toilets" that were outside of the house, like a small wooden shack (again, at daylight). He sits, opens a newspaper, then starts hearing footsteps outside. Then the creature's furry arm comes through the door and tries to grab him. They "wrestle" a little and the scene cuts. A few scenes later, it cuts back to the man telling his wife what happened while she washes him with a water hose from a distance, giving the impression that he was covered in shit because of the struggle.
That's it guys, it's all I remember. I'll be forever grateful if anyone can help me find this movie (if it really is just one). Thank you for your time.
