This is all of the cast Stephen can manage to give out.
The critics sorta liked it. They said it could have been much worse, but everything needs to end. Later, Stephen said "[[Us: Reborn|Us' not over yet. One more series to go until completion!"
In the first draft, there would be a reference to a game called "Mario Sports Mix", which came out at the time the first draft was written.
After this, it was planned Us would turn to TV movies. One would be called "Us: Roy's Doomship". This plan was cancelled at the last second.
