Films concerning "the double" or the doppelganger?

I need a list of films that shows "the double" or the doppelganger in film.

These can include not just physical, but also mentally, psychologically.



These can be movies similar to Black Swan, Fight Club, Dr. Jekyll and Mr. Hyde, and The Double Life of Veronique.



I'm just trying to find a list of films that are similar to the theme of the conflicting self.
