George Fox was a real person who lived from 1624-1691 and was one of the main figures in the founding of the Quaker movement.
The Wikipedia page on him is great—check it out.
While the film attempts to be true to his insights and theology, not all of the quotations are verbatim. Some were edited to modernize the language; some were edited to for length. For the scholars out there, below are the full quotations in some context, with links to the source material. I invite you to read
Fox's Journal and letters and the
writings of other Friends.
"I saw, also, that there was an ocean of darkness and death; but an
infinite ocean of light and love, which flowed over the ocean of
darkness. In that also I saw the infinite love of God, and I had great
openings."

Journal of George Fox, Chapter 1
"Be patterns, be examples in all countries, places, islands, nations, wherever you go, so that your carriage and life may preach among all sorts of people, and to them. Then you will come to walk cheerfully over the world, answering that of God in every one. Thereby you can be a blessing in them and make the witness of God in them bless you. Then you will be a sweet savor and a blessing to the Lord God."

To Friends in the Ministry
"Be still and cool in your own mind and spirit from your own thoughts, and then you will feel the principle of God to turn your mind to the Lord God, from whom life comes; whereby you may receive his strength and power to allay all blusterings, storms, and tempests."

Letter written in 1658
"But as I had forsaken the priests, so I left the separate preachers
also, and those esteemed the most experienced people; for I saw there
was none among them all that could speak to my condition. When all my
hopes in them and in all men were gone, so that I had nothing outwardly
to help me, nor could I tell what to do, then, oh, then, I heard a
voice which said, "There is one, even Christ Jesus, that can speak to
thy condition"; and when I heard it, my heart did leap for joy."

"At another time it was opened in me that God, who made the world, did
not dwell in temples made with hands. This at first seemed a strange
word, because both priests and people used to call their temples, or
churches, dreadful places, holy ground, and the temples of God. But the
Lord showed me clearly that He did not dwell in these temples which men
had commanded and set up, but in people's hearts; for both Stephen and
the apostle Paul bore testimony that He did not dwell in temples made
with hands, not even in that which He had once commanded to be built,
since He put an end to it; but that His people were His temple, and He
dwelt in them."

"Christ says this, and the Apostles say this but what can thou say? Are thou a child of Light, and have walked in the Light, and that thou speaks, is it inwardly from God?"
— Margaret Fell (Fox), quoting George Fox, in her
testimony after his death
"I was moved, also, to cry against all sorts of music, and against the
mountebanks playing tricks on their stages; for they burthened the pure
life, and stirred up people's minds to vanity."

(As you can see, George Fox probably would not have approved of popular music, music videos, or internet memes, even as a way of telling people about his realizations about God. Clearly I don't agree with him on this one.)
