I'm writing my term paper on the portrayal of the multiverse in works of fiction. So I'm looking for any type of fiction (movies, books, comics) that portrays the idea of the multiverse somehow, or even just fourth dimensional stuff.
So if you know of anything that features the multiverse theory, let me know! I would really appreciate it.
Although there is one thing I'm not looking for, TV series. I don't have the time to anolyze those.
