anywhere from a week, two weeks, to a few months.

Not only because it's action,

but because it also helps the director

tell the story of the film.

Hi, my name's Alyma Dorsey and I'm a stuntwoman.

I've been in "Jumanji 2", [ping ringing] "Baywatch",

and "Ghostbusters", [ping ringing] and we're here today

to look at how stunts are done in comedy, and action film.

[rhythmic beat]

This is "Mission Impossible - Rogue Nation". [intense music]

Oh, this is such an epic scene for Tom Cruise

because you know, that is him doing this stunt.

What I love about that

is that was probably some kind of wire gag.

[ping ringing] At least that's how I would've done it.

I could've put my stunt person on the wire.

Kudos for him!

There's a lot of precautions

for actors doing their own stunts,

just because of the liability that goes along with it.

If an actor gets hurt,

it could actually shut down production.

A lot of times the actors want to do their own stunts,

and if they're athletic and they are familiar

with the kind of gag that we're doing,

we want to keep them as safe as possible.

So, yeah it's great that they might wanna do the action

but we also have to make sure that we get through the film,

without the actor getting hurt which is why we have

the stunt men and and women come in there

and put their lives on the line,

so that the actor doesn't have to do that.

This is "Casino Royale".

[suspenseful music]

That right there is so hard.

I mean, can you imagine running at that angle?

People really don't even understand how hard it is,

to try to jump from one thing to the next

and pretend to fall.

Regardless of the safety lines that you might have attached,

just hitting your chest up against the bar,

your arms up against the bars repeatedly,

those things are super-brutal.

How crazy is that?

Hard core guys really can do that.

The way that they land and roll out of those,

is actually what makes those stunts very doable.

[intense music and banging]

That was a nice fall.

That was a really nice fall.

I wouldn't be as afraid to do that stunt

because there's so many different things

that they could've done to that material

to make it look like it's harder

than what it really is. [ping ringing]

So it kind of softened his fall a little bit.

[gun shots firing] [explosives going off]

On days like that, that's when they have us

bring our fire gear underneath our outfit or uniform,

so that if we do catch on fire

we do have a extra layer of protection there.

They would have someone, a safety team come out there

and actually extinguish all the guys

with the fire extinguisher.

And this is "Ghostbusters". [exciting music]

Oh, I love this!

Okay, so first let me say I love this film,

I love this film, I love this film,

and it is because [ping ringing] I'm in it,

let's put it that way!

The stunt that just happened was a ratchet.

So what a ratchet is, is you have a harness on

and you're connected to a wire,

and then there's a pressure system

where you have someone pushing a button,

or sometimes you can have a hand pull

where you have guys back there pulling on ropes

that are connected to the wire.

So he was literally yanked back about 20 feet.

[excited screaming] [audience wooing]

Did you see that bounce right there?

That bounce was real people, let me tell ya.

I actually jumped off of this stage,

it was about six feet up.

Whenever you do a high fall

you never want any points to hit.

So I wouldn't want my tailbone to hit first,

or my hip to hit first.

Pretty much wanna land on your back,

because that is the safest place to land.

I had a back protector,

a tailbone protector, with a proton pack.

So that bounce that you saw, was actually real.

So it was really fun, but it hurt, it was real.

- Okay, and I'm gonna open it, on three.

- That little push of this apparatus

across the stage, took us so long to do.

That little push was actually our stunt girl,

Meredith Richardson who's amazing.

You had to make sure to push that thing

in the right spot each time.

Sometimes it's just about hitting a mark,

and hitting a mark over and over consistently,

is a really difficult thing to do.

So kudos to Meredith on that one.

This is "Death Proof".

[engine revving drowns out actor's dialogue]

I actually love this film, for a couple of reasons.

Quentin Tarantino started my career,

as well as he started Zoe Bell's career.

- Take [ping ringing] that back. [engine revving]

- This is such a epic scene that we're about to go into

because, she's really doing this.

They are going super-fast.

Normally when you watch stunts,

they might go like 20 miles an hour or something,

but they are really going, really fast,

and the reason that I know this is actually,

Quentin Tarantino, we talk about this film

all the time, or we have in the past.

He really had to find a stunt woman,

who could give him what he wanted from this film.

He likes realness, he doesn't like to fake the fall.

You know, it's really amazing with stunts.

We're always putting our lives in someone else's hands.

For them to be going at super-excessive speeds,

Zoe being able to trust the stunt woman

that nothing's gonna happen to her

and that she can actually perform,

'cause she's acting in this film as well as doing stunts

which is another amazing thing.

The safety measures are very important.

There's different varieties of safety

when it comes to making sure

that a stunt person comes home at the end of the day.

One of the things that made this stunt

more safe than another, are the actual performers.

- Do you want it [bleep] faster?

- I saw a stunt woman pushing another stunt woman's limit,

but at the same time I saw the trust between them,

knowing that they were friends,

that they weren't gonna hurt each other,

but still testing each other and pushing each other.

And so they had that comradery.

So the reason why the stunts actually come out so well,

at the end of the day,

we always have each other's back, no matter what.

We might be the one that pushes you to the edge,

but we're also the one that will never let you fall over.

This is "The Legend of Drunken Master".

[animated shouting] [intense music]

Okay, Jackie Chan is my favorite of all times.

This is real stunt work right here.

This is like the real deal.

It doesn't get more real than this.

[karate fighting]

I mean just the timing of these fights.

For them to be able to go this fast, and hit every mark,

every expression, is one of the things that

the younger generation stunt people strive to be like.

[screaming and banging]

That hit, that side hit to the ground, you know,

was him actually hitting the ground.

It isn't like they had anything there,

there was nothing there to soften his fall.

That's one thing about Jackie Chan he's known for,

I mean he got hurt a lot.

[scorching flames] There's different ways

to protect your skin and body from fire.

Normally they have a gel

face covering [ping ringing] over their skin.

It takes some time for that fire, to get through that gel.

Now sometime means a few seconds,

but most importantly you have an experienced fire team.

A safety team that's ready to make sure

that that stunt performer's okay,

and they can put that fire out in a timely manner,

because that gel only lasts but for so long.

This is "Steamboat Bill, Jr."

[jazz piano music]

Ahh, what I love about this...

This is Buster Keaton.

Back in the day they didn't have pads.

This is like, I always joke with the old stunt guys,

I'll call 'em like, BP, before pads.

You know, like, instead of BC, Before Christ,

it's like, BP, before pads.

I take my hat off to all of the stunt men and women

that came before me because,

they don't have any kind of protection whatsoever.

They just have to know how to fall.

Back then, you were supposed to be tough.

There's really no protection there.

He really jumped, on a mattress,

which is somethin' we would never do that today.

We always have some kind of protection.

[jazz piano music]

So cool, it's all about your marks, but just to trust,

that's really what that whole scene right there

to me was all about, was trust in safety,

to trust that house is gonna fall,

or that part of the house is gonna fall

in the same spot each time, and you can't flinch,

and you can't anything is pretty amazing.

This is "Bad Boys for Life".

[bullets firing] [suspenseful music]

The lay downs that all the stunt guys

are doin' is pretty phenomenal.

[ping ringing] They really picked a very talented group

of motorcycle stunt men in the shot. [explosion]

- Hit it! - Wow, that was super-cool.

Did they have someone?

Was the writer still on there?

I don't know, I don't think the writer was still on there.

I think the way they had the camera set up,

that didn't really have to be a real person

on that bike when it landed.

It could've been a dummy, possibly?

The way it was shot,

you really don't have to see the person in particular,

like details of that person, and it's super-dangerous

to where you don't necessarily need

to put that stunt man's life in danger,

then I think that that's the best time to use a dummy.

[shrieking and wailing] [intense music]

Oh, those are two fun stunts back-to-back.

So, the first one was really cool

because that was all about timing as well.

That stunt performer had to really be dependent

on the stunt driver making sure to maintain that speed

so that stunt person can actually know

when the perfect timing was for him

to actually push off of his pegs,

and then do a shoulder roll onto the bed of the truck.

Him going into the barrels.

The barrels are not something that's too hard to go into,

it's just a matter of protecting yourself

as you're goin' through there.

They probably did a [beeping] Cowboy Switch

at the end where the stunt performer went through,

and then on the next shot where you see the actor

you'll actually see Martin.

Oh my God, that was so awesome, I had such an amazing time

just getting a chance to go through all the stunts.
