I'm trying to identify an old movie from a single scene. At that time I was a child, the movie seemed to be kind of a sci-fi/horror genre, my parents didn't let me see the whole movie, I just clearly remember that single scene.
I can suppose it was a sci-fi movie, and it could be from the '80s, for sure older than 1994. It is probably set on a spaceship. We see a woman immobilized on something like a surgical table, then a little circular saw moved by a robotic arm that is going (I suppose) to slice the woman's body for some experiment or maybe just in order to kill her (for example onboard computer getting mad), the woman reasonably starts screaming and then we see some blood splashing over the table. Nothing else.
We don't see (at least in that scene) any alien creatures, just the woman and the saw and the blood.
