Doctor Strange (2016)

Kaecilius: You'll die defending this world, Mister...
Dr. Stephen Strange: Doctor.
Kaecilius: Mister Doctor?
Dr. Stephen Strange: It's Strange.
Kaecilius: Maybe. Who am I to judge?

The Ancient One: You think you know how the world works? You think that this material universe is all there is? What is real? What mysteries lie beyond the reach of your senses? At the root of existence, mind and matter meet. Thoughts form reality. This universe is only one of an infinite number. Worlds without end; some benevolent and life-giving, others filled with malice and hunger. Dark places where powers older than time lie, ravenous and waiting. Who are you in this vast multiverse, Mr. Strange?

Dr. Stephen Strange: This doesn't make any sense.
The Ancient One: Not everything does. Not everything has to.

The Ancient One: We never lose our demons, we only learn to live above them.
