Unfortunately I can't narrow it down other than saying "science fiction"
since that's the closest genre. I have something coming up on 350
science fiction movies under my belt, and I'm sorry but I've never
thought to note cloning (or multiple-selves) as a movie feature.

There is the obvious biological cloning but there are movies where a
character learns it's a copy of a brain pattern in an android. Hendrik
is right in that for almost all these movies the clone twist is meant
as a revelation for the viewer to think about the nature of self.
Giving a list of titles would ruin a viewer's innocence.

I did some digging, and if you'd like I can recommend/spoil a movie or
two for you. :)
