Hi,

I am looking for the title of a movie I saw when I was a child.
Movie should have been produced in 80’s or late 70’s.

In a post apocalyptic world, people is separated in two :
– “wild” ones riding horses, and living in difficult conditions (war, assaults, etc.)
– high tech people living under a dome, close to immortality

The second ones are facing a health problem :
– some people seem to loose their brain and just stand, doing nothing
– fecundity issues : they are not able to make love any more (they don’t even know how it works)
So, they capture a wild man (which will become the hero) in order to understand how to reproduced themselves.

I am not sure about the ending, and I don’t want to spoil 😉

Thanks for your help
