You need to watch Dr StrangeHad to look it up not familiar with Dr Strange. Certainly some similarities including being larger inside than it would appear from the outside, a labyrinth of rooms with all the additions we've put on and magical places within ...my theater.
Cool scifi ending.
Even more amazing there is no 4K UHD disc release!?
If you are into Eastern Hindu/Buddhist/New Age/astral philosophies, Dr Strange is your superhero
EDIT- 4K Disc released Oct 2019! Usual Disney 4K issues may apply
