Rodger: My name's Rodger Cornell.
[4]
I'm an explosives engineer.
[10]
Will Ferrell: Oh my god,
how do they walk away
[11]
in movies without flinching
when it explodes behind them?
[14]
There's no way!
[25]
Rodger: Okay so as soon
as this clip starts
[28]
there are a couple of
really pressing issues
[29]
that you should be focusing on.
[31]
The first is if you have grenades
[33]
and other weapons, you
shouldn't be carrying them
[34]
around inside a guitar case.
[38]
On top of that, as soon as
he pulls the grenades out
[39]
you'll notice that he pulls out not one
[41]
but two of those pins with his teeth.
[45]
I've tried it a few
times, and you really have
[46]
to put all of your strength
to get that thing dislodged.
[49]
So pulling any kind of grenade
pin out with your mouth
[51]
unless it's been tampered with beforehand
[54]
is just completely unrealistic.
[56]
Antonio Banderas: Jesus Christ.
[57]
Rodger: The most common
misconceptions I'm aware of.
[59]
One is that any explosive device
[62]
when it goes off will throw a human being
[64]
into the air. The detonation itself
[66]
and the pressure wave,
they're gonna do plenty
[68]
of damage to the human body.
[70]
Propelling you into the air isn't gonna
[71]
be one of the things that you experience.
[73]
So being thrown is not really a thing.
[86]
You also see that just
from those two grenades,
[88]
you have this gigantic fireball.
[90]
Grenades, especially a
military grenade, is gonna
[92]
be composed of what's
called secondary explosives
[95]
and these secondary explosives go
[97]
through detonation processes.
[98]
A detonation process is extremely rapid
[101]
and it's certainly not gonna
[102]
be this prolonged explosion
that you see here.
[117]
When you see a gigantic fireball
[118]
and you see just flames everywhere
[120]
and you can usually assume
[121]
that they're exaggerating quite a bit.
[123]
I mean it's not that surprising.
[125]
It's a Quentin Tarantino movie,
[126]
so I really wouldn't expect anything less.
[129]
The only explosive device that you see
[131]
in that clip is what seems
to be one pack of dynamite.
[135]
Dynamite's used specifically
for blasting operations
[138]
so even though it's made
for situations like this
[142]
if you have just one bundle in the corner
[144]
of a house, you will never
get any kind of an explosion
[147]
on this order, you might have
a chunk of the house missing
[151]
right where that explosive charge was
[152]
but that's about it,
the house would probably
[154]
still be standing, unless there were a lot
[156]
of other charges placed about the house
[157]
that we're unaware of.
[159]
Certainly not every piece
[160]
of the building would be in flames.
[162]
Samuel Jackson: Son of a--
[174]
It looks like he's in a dummy town.
[177]
Once he hears sirens, he realizes
[179]
that he's about to be in the
middle of a nuclear test.
[181]
Harrison Ford: That can't be good.
[188]
Rodger: The refrigerator's lead lined
[189]
and the reason this is important is
[191]
that the lead can actually
block certain types
[193]
of radiation. So that's the premise
[195]
is that all the lead
in this fridge is gonna
[197]
block the radiation and
somehow protect Indiana Jones.
[201]
Some of the things that are
depicting are somewhat accurate.
[204]
I mean, a nuclear detonation
or a nuclear event
[206]
would produce all kinds of light.
[210]
And it's amazingly destructive.
[214]
So they're showing the
force of it correctly
[217]
just not how it's gonna impact the fridge
[219]
which is the main issue with the scene.
[220]
Sure, the lead lining is
gonna protect a little bit
[223]
from some of the radiation,
although it's not nearly enough
[225]
to prevent all of the radiation
[227]
from affecting you, there's
no way you can survive
[229]
an impact like that.
[231]
The fact that he gets out immediately
[232]
and he'll actually walk up to look
[234]
at the aftermath of the mushroom cloud
[236]
from the nuclear event, there's
a ton of nuclear fallout
[239]
when you have these events, and you want
[241]
to be as far away from this as possible
[243]
because the radiation that it produces
[245]
it sticks around for quite a while.
[247]
And the fact that he lives on in the movie
[249]
and doesn't die in a couple hours
[250]
from radiation sickness is
just completely ridiculous.
[267]
Right off the bat
[268]
it's Michael Bay, it's
a Transformers movie
[271]
you have Deceptacons running around.
[274]
So how real can you expect it to be?
[276]
When you see the fighter jets in action
[278]
you'll notice these bursts of
light coming off the bottom.
[284]
If I had to guess what that was,
[285]
that would probably be flares.
[286]
And a lot of times
they're used so the planes
[288]
can avoid heat seeking missiles.
[290]
They're a source of heat
that can distract the missile
[293]
from continuing to fly towards the jet.
[295]
Now whether or not the Deceptacons
[297]
use heat-seeking missiles I have no idea.
[300]
Traffic Controller: Q1 snipe 090.
[301]
You are approved to drop
your 2000-class JDAMs.
[304]
Rodger: So during this initial explosion,
[306]
what I'm assuming they're
doing is essentially
[309]
marking their target.
[310]
If you're gonna drop ammunition
[312]
that don't have any kind of propulsion
[314]
or guidance, you want
to be very, very sure
[317]
where you're gonna drop those bombs.
[327]
You see Shia LaBeouf get
just almost catapulted
[331]
into the air, it almost
actually looks like he's
[333]
stepping on like a trampoline.
[338]
I can't see any reason why he would
[339]
be tumbling in the air like that.
[341]
The pressure wave that's radiating
[344]
is moving outward, away from the explosion
[348]
so if you were to be thrown at all
[350]
you might be thrown backwards
and fall to the ground
[352]
but setting that all aside,
[354]
there's at least realistic situations.
[356]
Some of the things that the aircraft did
[359]
that progression from marking your target
[362]
and then dropping the
energetic load on top of it
[364]
my guess is that he was probably consulted
[366]
as to how the Department
of Defense would actually
[369]
go through their procedures.
[383]
He takes essentially his claws
[386]
and he strikes them against the rocks
[387]
to create a spark to initiate the flame.
[390]
If I'm remembering
correctly, it's Adamantium
[392]
what his claws are made of,
which is completely fictitious.
[395]
I have no ideas what the properties of
[396]
that material would be, but
there are a lot of metals
[398]
out there that don't spark.
[400]
There are other ways to initiate fuel.
[403]
That seems like a pretty silly one
[404]
that probably wouldn't work out.
[405]
That's a very rocky surface.
[408]
Even if you got it to start burning
[409]
it would probably die out
[410]
before it ever reached the helicopter.
[412]
I would never expect this to explode.
[414]
You have a helicopter that's crashed
[416]
and that's already leaking fuel.
[418]
So when the fuel tank ruptures
[420]
there's no pressure
vessel that can heat up
[423]
that can allow pressure to build
[424]
where you'd actually get
some sort of an explosion.
[426]
But if you had an explosion on that scale
[429]
you'd have pieces of that
helicopter being thrown
[432]
in every direction, not to
mention the pressure wave
[434]
that's produced, so he would definitely
[437]
hit the ground at some point.
[438]
He regenerates, so I guess
you could walk away from this.
[441]
He'd be fine.
[454]
You see some grenade
being launched at Hancock.
[460]
And he somehow deflects it into a car.
[463]
If we just accept the
fact that he can't be hurt
[465]
and that he can just deflect bullets
[466]
and that's fine, there's
still really big issues
[469]
with this scene. The effect of the grenade
[471]
is unrealistic, the way
it initiates is incorrect
[475]
using the police car as a way
[478]
of stopping bullets is just ill advised.
[482]
Cars don't stop bullets.
[484]
Cars can deflect bullets.
[485]
Cars have a lot of weak points,
[487]
so you wouldn't want to
ever use it as a shield.
[490]
I would expect the doors to
have bullet-proof inserts
[492]
but that's about it.
[494]
The roof of the car and
the floor of the car
[497]
are probably pretty thin, those are gonna
[499]
be the most vulnerable
parts of that vehicle.
[501]
The way he's holding it is
probably the least safe way
[504]
that he could be using
that car for protection.
[507]
Will Smith: Good job!
[520]
To create an explosion that massive
[523]
you would need more explosive material
[525]
than you could carry with you
[527]
and you would need to plant it everywhere.
[529]
It would take just unlimited
financial resources
[533]
a huge amount of time to place the charges
[535]
where you need to put them.
[536]
They try to add in some
cool sound effects.
[544]
It's not gonna sound anything like that.
[545]
The actual audio event is very rapid
[551]
very loud, and it's more of a crack.
[557]
They try to show the shock
actually moving outward
[561]
essentially past Denzel,
you can see the grass
[563]
start to move forward,
and then retract back.
[567]
There, you see that little.
[569]
That was a shock wave moving past,
[571]
so seeing that sort of
motion within the grass
[574]
in that scene could actually be realistic.
[577]
If you're that close where
you can see the shock
[579]
around you, it's gonna at least hurt
[582]
because you have this
sudden change in pressure.
[585]
It's gonna feel like
someone's at the very least
[587]
just punching you as hard as they can.
[589]
You're not just gonna keep walking.
[591]
All sorts of metal being thrown.
[593]
There's fragmentation everywhere.
[611]
This is one of my favorite movies
[612]
so I really hate
[614]
laying into it like I'm about to.
[617]
So he essentially rigged this hospital
[618]
with explosives, he's
setting them off wirelessly
[622]
and then he's just watching
as the demolition unfolds.
[626]
You could have explosions
going off at different times
[629]
and different locations
[630]
so that's actually not unreasonable.
[632]
What is unreasonable is
to pull that off would
[635]
be expensive, and you'd
also need to somehow
[637]
go through a hospital and
place all these charges
[641]
without anybody noticing,
I'm not entirely sure
[644]
that he would have the resources
[646]
the time, and be able
to disguise everything
[650]
to actually pull something like this off.
[651]
Especially given what the Joker's wearing.
[655]
Heath Ledger: Hi.
[656]
There's no way he would go
through this entire process
[659]
without being seen by somebody.
[666]
Jonah Hill: It's gonna explode!
[667]
Channing Tatum: Oh my
god, roll up the windows!
[668]
Jonah: What the f*** is that?
Channing: Roll it up!
[668]
Channing: I don't care just do it!
[672]
- The funny thing is, this scene is one
[674]
of the most realistic scenes
we're probably gonna see.
[677]
There is one resounding
issue with this scene though.
[680]
All those pressurized tanks, the fact
[682]
that all these things are ruptured
[684]
and just sitting there.
[685]
Jonah: What happened?
[686]
Channing: I don't know.
It just didn't explode.
[687]
Jonah: That's weird.
[688]
That would never happen.
[696]
Jonah: I really thought
that one was gonna explode.
[698]
This I think is actually
the most accurate scene
[700]
so you have a fuel tank
that was just riddled
[704]
with bullet holes, so it has no way
[706]
of accelerating the reaction.
[715]
Channing: That's what exploded?
[717]
I don't know why chickens would explode.
[718]
Their fecal matter could probably combust
[721]
the wooden cages could light on fire
[723]
but why you'd get an
explosion, I have no idea.
[726]
I think the scene's kind of intending
[728]
to be a bit ridiculous,
and it definitely is.
[738]
Will: What accounting firm is
closed at 11 AM on a Tuesday?
[742]
Mark Wahlberg: Oh this is a s***hole.
[745]
The flame's unrealistic, but
the way they're pushed back
[749]
is actually somewhat believable.
[751]
So the fact that they aren't cut up
[753]
and that they're not bleeding profusely.
[755]
The fragmentation in that situation
[757]
would be much more deadly.
[758]
Will: I can't hear!
[760]
I can't hear!
[761]
The way he's complaining is unrealistic
[764]
but the fact that he's complaining
[765]
about his ears is actually realistic.
[768]
When you have blast over pressure
[770]
there are certain parts of the human body
[772]
that are susceptible, are very susceptible
[774]
to shifts in pressure.
[776]
Your ear drums are one,
and your lungs are another.
[779]
In extreme cases, if the
pressure was strong enough
[781]
you could rupture your
lungs, and if that happens
[785]
or if anything near that happens
[786]
he's not gonna be talking.
[788]
He's just gonna be laying there gasping
[789]
for whatever breath he can pull in
[791]
so he seems to be in much better shape
[793]
than I would imagine him to be.
[795]
If you got hit with a pressure wave
[796]
you'd probably be concussed as well.
[799]
Will: I need an MRI!
[801]
So an MRI might not be a bad idea.
