I was watching TV in the 1990's in the UK which was showing either a movie or TV show.
I only remember that in the scene I saw that two characters, where at least one was male, had crashed, or were transported, to an alternative planet/dimension/time period.
In the scene they are 'captured' by a 'strong (Amazonian) woman' trope. They are then sent to the 'factory' here they are 'fixed' along with a large number of other 'natives'. I can't remember if that was mentally or physically. One of the captors leans in to the prisoners just before the process happens and says something like 'we won't actually do it to you, but you have to behave yourselves.'
The whole thing seemed very kitschy, and maybe quite dated. It could have been produced in the 80s, and it might have been in the same style as Barbarella and that kind of movies.
I have no real idea about anything else, as I saw this when I was quite young, maybe 5-10, which was also 20 years ago.
