and when I worked on this film, I discovered something

about how our brains work, and how our brains work

is that, when we're sort of infused with

either enthusiasm or awe or fondness or whatever,

it changes and alters our perception of things.

It changes what we see. It changes what we remember.

And as an experiment, because I dauntingly create

a task for myself of recreating a Saturn V launch

for this particular movie, because I put it out there,

I felt a little nervous about it, so I need to do an experiment

and bring a group of people like this in a projection room

and play this stock footage, and when I played this

stock footage, I simply wanted to find out

what people remembered, what was memorable about it?

What should I actually try to replicate?

What should I try to emulate to some degree?

So this is the footage that I was showing everybody.

And what I discovered is, because of the nature

of the footage and the fact that we're doing this film,

there was an emotion that was built into it

and our collective memories of what this launch meant to us

and all these various things.

When I showed it, and I asked, immediately after

the screening was over, what they thought of it,

what was your memorable shots, they changed them.

They were -- had camera moves on them.

They had all kinds of things. Shots were combined,

and I was just really curious, I mean, what the hell

were you looking at just a few minutes ago

and how come, how'd you come up with this sort of description?

And what I discovered is, what I should do is not actually

replicate what they saw, is replicate what they remembered.

So this is our footage of the launch, based on, basically,

taking notes, asking people what they thought, and then

the combination of all the different shots and all

the different things put together created their sort of

collective consciousness of what they remembered

it looked like, but not what it really looked like.

So this is what we created for "Apollo 13."

(Launch noises)

So literally what you're seeing now is the confluence

of a bunch of different people, a bunch of different memories,

including my own, of taking a little bit of liberty

with the subject matter.

I basically shot everything with short lenses,

which means that you're very close to the action,

but framed it very similarly to the long lens shots

which gives you a sense of distance, so I was basically

was setting up something that would remind you

of something you haven't really quite seen before. (Music)

And then I'm going to show you exactly what it is

that you were reacting to when you were reacting to it.

(Music)

Tom Hanks: Hello, Houston, this is Odyssey.

It's good to see you again. (Cheers) (Music)

Rob Legato: I pretend they're clapping for me.

(Laughter)

So now I'm in a parking lot. Basically it's a tin can,

and I'm basically recreating the launch with

fire extinguishers, fire, I have wax that I threw

in front of the lens to look like ice, and so basically

if you believed any of the stuff that I just showed you,

what you were reacting to, what you're emoting to,

is something that's a total falsehood, and I found that

really kind of fascinating.

And in this particular case, this is the climax of the movie,

and, you know, the weight of achieving it was simply

take a model, throw it out of a helicopter, and shoot it.

And that's simply what I did.

That's me shooting, and I'm a fairly mediocre operator,

so I got that nice sense of verisimilitude, of a kind of,

you know, following the rocket all the way down,

and giving that little sort of edge, I was desperately

trying to keep it in frame. So then I come up to the next thing.

We had a NASA consultant who was actually an astronaut,

who was actually on some of the missions, of Apollo 15,

and he was there to basically double check my science.

And, I guess somebody thought they needed to do that.

(Laughter)

I don't know why, but they thought they did.

So we were, he's a hero, he's an astronaut, and

we're all sort of excited, and, you know, I gave myself

the liberty of saying, you know, some of the shots I did

didn't really suck that bad.

And so maybe, you know, we were feeling kind of a little

good about it, so I brought him in here, and he needed

to really check and see what we were doing,

and basically give us our A plus report card,

and so I showed him some shots we were working on,

and waiting for the reaction that you hope for,

which is what I got. (Music) (Launch noises)

So I showed him these two shots,

and then he basically told me what he thought.

("That's wrong") (Laughter)

Okay. (Laughter)

It's what you dream about.

(Laughter)

So what I got from him is, he turned to me and said,

"You would never, ever design a rocket like that.

You would never have a rocket go up

while the gantry arms are going out. Can you imagine

the tragedy that could possibly happen with that?

You would never, ever design a rocket like that."

And he was looking at me. It's like, Yeah, I don't know

if you noticed, but I'm the guy out in the parking lot

recreating one of America's finest moments with

fire extinguishers.

(Laughter)

And I'm not going to argue with you. You're an astronaut,

a hero, and I'm from New Jersey, so --

(Laughter)

I'm just going to show you some footage.

I'm just going to show you some footage, and tell me what you think.

And then I did kind of get the reaction I was hoping for.

So I showed him this, and this is actual footage

that he was on. This is Apollo 15. This was his mission.

So I showed him this, and the reaction I got was interesting.

("That's wrong too.") (Laughter)

So, and what happened was, I mean, what I sort of intuned

in that is that he remembered it differently.

He remembered that was a perfectly safe sort of gantry

system, perfectly safe rocket launch, because he's sitting

in a rocket that has, like, a hundred thousand pounds

of thrust, built by the lowest bidder.

He was hoping it was going to work out okay.

(Laughter) (Applause)

So he twisted his memory around.

Now, Ron Howard ran into Buzz Aldrin, who was not

on the movie, so he had no idea that we were faking

any of this footage, and he just responded

as he would respond, and I'll run this.

Ron Howard: Buzz Aldrin came up to me

and said, "Hey, that launch footage, I saw some shots

I'd never seen before. Did you guys, what vault did you find

that stuff in?" And I said, "Well, no vault, Buzz,

we generated all that from scratch."

And he said, "Huh, that's pretty good. Can we use it?"

(Explosion) ("Sure") (Laughter)

RL: I think he's a great American.

(Laughter)

So, "Titanic" was, if you don't know the story,

doesn't end well.

(Laughter)

Jim Cameron actually photographed the real Titanic.

So he basically set up, or basically shattered

the suspension of disbelief, because what he photographed

was the real thing, a Mir sub going down, or actually

two Mir subs going down to the real wreck,

and he created this very haunting footage.

It's really beautiful, and it conjures up all these

various different emotions, but he couldn't photograph

everything, and to tell the story,

I had to fill in the gaps, which is now rather daunting,

because now I have to recreate back to back

what really happened and I had, I'm the only one

who could really blow it at that point.

So this is the footage he photographed,

and it was pretty moving and pretty awe-inspiring.

So I'm going to just let it run, so you kind of absorb

this sort of thing, and I'll describe my sort of reactions

when I was looking at it for the very first time.

I got the feeling that my brain wanted to basically

see it come back to life.

I automatically wanted to see this ship,

this magnificent ship, basically in all its glory,

and conversely, I wanted to see it not in all its glory,

basically go back to what it looks like.

So I conjured up an effect that I'm later going to show you

what I tried to do, which is kind of the heart of the movie,

for me, and so that's why I wanted to do the movie,

that's why I wanted to create the sort of things I created.

And I'll show you, you know, another thing that I found

interesting is what we really were emoting to

when you take a look at it.

So here's the behind the scenes, a couple of little shots here.

So, when you saw my footage,

you were seeing this: basically, a bunch of guys

flipping a ship upside down, and the little Mir subs

are actually about the size of small footballs,

and shot in smoke.

Jim went three miles went down, and I went about

three miles away from the studio

and photographed this in a garage.

And so, but what you're emoting to, or what you're looking

at, had the same feeling, the same haunting quality,

that Jim's footage had, so I found it so fascinating

that our brains sort of, once you believe something's real,

you transfer everything that you feel about it,

this quality you have, and it's totally artificial.

It's totally make-believe, yet it's not to you,

and I found that that was a very interesting thing

to explore and use, and it caused me to create the next

effect that I'll show you, which is

this sort of magic transition, and all I was really attempting

to do is basically have the audience cue the effect,

so it became a seamless experience for them,

that I wasn't showing you my sort of interpretation,

I was showing you what you wanted to see.

And the very next shot, right after this --

So you can see what I was doing.

So basically, if there's two subs in the same shot,

I shot it, because where's the camera coming from?

And when Jim shot it, it was only one sub,

because he was photographing from the other,

and I don't remember if I did this or Jim did this.

I'll give it to Jim, because he could use the pat on the back.

(Laughter)

Okay. So now the Titanic transition.

So this is what I was referring to where I wanted to basically

magically transplant from one state of the Titanic

to the other. So I'll just play the shot once. (Music)

(Music)

And what I was hoping for is that it just melts in front of you.

Gloria Stuart: That was the last time Titanic ever saw daylight.

RL: So, what I did is basically I had another

screening room experience where I was basically tracking

where I was looking, or where we were looking,

and of course you're looking at the two people on the bow

of the ship, and then at some point,

I'm changing the periphery of the shot,

I'm changing, it's becoming the rusted wreck,

and then I would run it every day, and then I would find

exactly the moment that I stopped looking at them

and start noticing the rest of it, and the moment

my eye shifted, we just marked it to the frame.

The moment my eye shifted, I immediately started

to change them, so now somehow you missed

where it started and where it stopped.

And so I'll just show it one more time.

(Music) And it's literally done by using what our brains

naturally do for us, which is, as soon as you shift
