Then, you go back and look at the comics, and look at the journey that the Ancient One would take Strange on, when he first got to the comics.
They didn’t know about parallel dimensions back then, but they were either making it up, or tapping into other philosophies for it, and now I think it’s more relevant, and potentially, theoretically more realistic than ever.
We looked at that a lot, because of the discussions [we were having] about parallel dimensions and multiple dimensions and all of that has gone into building the foundation for our fictional reality within this Strange universe.
