I had a chance to speak with Heidecker as part of the new Blu-Ray release of Us, and he told me That Us doesn’t need anymore story to be told, because everything you need to know about the world is in the movie itself.
However, one person that isn’t losing any sleep over what happens after Us fades to black is Tim Heidecker, who plays both the character of Josh and his “tethered” doppelganger Tex, in the film.
