Making the Astral Forms of ‘Doctor Strange’

You're exiting your body

and you're viewing something from an alternate dimension.

So, that's a big moment for us to figure out

how we're gonna do that.

It'll start off often at Marvel in the vis dep department.

They'll come up with concepts.

Pre-vis is essentially moving storyboards.

You actually can now get into what the shots

are supposed to be like, how dynamic the moves are.

That then gets handed off to a facility

who will then begin testing that with moving footage.

[Man] Action!

Now!

We were testing today the astral push moments.

In those moments we're shifting into a high speed.

So, we're testing frame rates as well as camera speeds

in order to do that.

The astral form is one of the simplest effects

that we've done and one of the hardest

because you need to believe that in way

is the spirit that, sort of, comes out of the body.

We all know what the body looks like

and we also what a ghost looks like.

The idea was that we didn't want it to look like a ghost

and, yet, is ghostly.

The main thing was in the way they can move

and interact with the environment

When they fly very fast through the room

they can go through the walls

but then cling to the walls,

things are moving when they hit them.

So, it's not really ghosts as we know them.
