Movie science 101.

[Rev. Powell]

If you replace your blood with embalming fluid, you'll go into suspended animation. If you pump out the embalming fluid and pump blood back in, you'll be good as new. (DR. PHIBES RISES AGAIN)

[Chainsawmidget]

Careful though, the human body contains over 15 gallons of blood and it's often under high pressure. 

[Mean Machine]

When a "fusion reactor" is damaged it will inevitably begin building up an "overload" which will unavoidably result in it exploding in the near future. Apparently technicians, scientists and engineers in the future, despite achieving controlled thermonuclear fusion, have lost the ability to install shutdowns on the fuel feed to the reactor to avoid overloads and explosions.

Every computer on the planet is hooked into the same network which can always be easily hacked into...

You can drive a truck through sub-atomic space (Buckaroo Banzai)

The main component in the manufacture of cars appears to be explosives.

Every computer on the planet is hooked into the same network which can always be easily hacked into...

Using a GUI that simulates the hacker removing physical obstacles to find information represented by objects in 3D space.

And as an addendum to the rules of atomic radiation: Any random mutation, whether by radiation, chemicals or other genetic alteration, will result in a viable creature which, in spite of its misshapen appearance, will be more robust, overall, than a healthy organism, and possess various adaptations that make it very deadly and difficult to kill. The mutation will seldom, if ever, result in a debilitating deformity, terminal cancer or any kind of ill health. Physical health, that is. Mental health usually takes a turn for the worse.

I'll do you one better. Jeff Goldblum was able to hack an alien computer network and infect it with a virus in Independence Day, because, alien computer network operating systems are similar enough to our own that we could do such a thing, right?

[Mean MAchine]

Not to defend ID4 because it was a huge letdown for me, but technically I think the reason goldblum could hack into the alien's computers was that their and out computers were very similar because out computers had been reverse engineered from the alien fighter at hanger 18.

You can easily outrun a nuclear explosion (Broken Arrow) or failing that, just hide in a refrigerator. (Indiana Jones)

[Automan2k]

The ice ages were the result of giant ice hurricanes and not all that nonsense about gradual expansion of glaiciers. (The Day After Tomorrow)

[WildHoosier09]

I wish there were some people who could test out these movie science myths, maybe they could have a show on discovery channel.....

I must admit that although I found the movie as a whole decent (maybe a C+, being generous) some of the biggest sins against the laws of science and physics were committed by Indiana Jones Crystal Skull: for me the most blatant was the monkey swing.  Just because a 10lb monkey can swing from some 1/8inch thick vines doesn't meant three full grown adults can and also out manuever vehicles on the ground.

Also (this is several movies, most blatant is Armagedon but I think there was also Deep Impact and maybe a few others with this motiff) if an asteroid heads for earth the last thing the US govt or any competent entity would do would be to send some slack-jawed oil rig workers up to drill in a nuclear bomb.  If you put a nuclear bomb a little to the right of the asteroid you will push it to the left, tada disaster averted. You don't need to obliterate it, just push it around. Also, is it just me or did the asteroid in Armagedon have some pretty good gravity for something so small.  Yes, I know they jump the car thing over the grand canyon but the also do alot of calmly walking (not floating) around almost like they were under 1G of gravitational force in a film studio.

Giant prehistoric monsters of all sorts, but mostly dinosaurs, can live for hundreds of millions of years frozen in Arctic ice with no ill effects.

lol... actually the alien controls are simular to a fighter jet, although the aliens look like giant squids... :)

You're absolutely right, but obliterating it is more entertaining.
