Kevin Feige habla sobre cómo la versión del co-creador del personaje de los otros mundos inmateriles ha influenciado la película:
"We see glimpses of something called the Dark Dimension.
If you were to open a 'Doctor Strange' comic drawn by Steve Ditko, you would see the Dark Dimension is, in fact, very colorful in an extremely psychedelic way.
Those are the things we're not shying away from."
"The film couldn't be any more different than any of the films that have come before it...
There are more things that lurk in shadows in this movie, perhaps, than our other movies."
