It wouldn't crush, but if it was exceptionally weak, it might explode as the vacuum of space. It wouldn't do either though because the movie suits behave a little more realistically than the comic ones. They aren't paper thin or tearable.
stuff doesn't explode in the vaccuum of space.

Exploding Body in Vacuum
By Karl S. Kruszelnicki
The Governor of California, Arnold Schwarzenegger, has had previous careers in body-building and making movies. In the movie, Total Recall, the hero, Quaid, played by Arnie, begins to expand when he is exposed to the incredibly thin atmosphere of Mars. In a desperate effort to survive, he holds his breath, and instantly his face bulges horribly and his eyeballs begin to swell dangerously, as he heads down the pathway towards exploding. Luckily, and with miraculous timing, an ancient alien artifact chugs into activity, and almost instantaneously makes enough atmosphere to restore his size back to normal and let him breathe again. So here's the question - will we humans explode in the full vacuum of space, as urban legends claim? The answer is that we won't explode, and if the exposure is short enough, we can even survive.
But why do people think that we explode, when exposed to a vacuum?
First, there is the word "explosive" in the term "explosive decompression". "Explosive decompression" happens when all the air in a smallish plane is lost in less than one half-second, and is usually accompanied by a loud noise. More common is the "rapid decompression" that can happen in larger planes - it takes between one half-second and ten seconds. Finally, there is the "subtle decompression" that takes longer than ten seconds, and can be caused by the cabin altitude pressure being set wrongly. So maybe the phrase "explosive decompression" is responsible for the mythconception that we explode in a vacuum - but in truth, the term refers to how suddenly the pressure drops, not what happens to the people exposed to that pressure drop.
Second, there is the correct belief that the pressure inside our body pushes against the weight of the air pressing against our skin - so putting us in a state of perfect balance. At ground level, the air pressure is about 10 tonnes per square metre. (That means that if we measure out a one metre square in the backyard, and weigh all the air above that square - going right up to space - we will find that the air weighs about 10 tonnes). So to create a balance against this weight of air, each square metre of our body pushes back with 10 tonnes. A tall person might have a surface area of nearly two square metres, which means that the total weight of air on the skin is about 20 tonnes. If we remove the external pressure, then surely the internal pressure of our body's tissues will make it explode?
The answer is no. Skin is quite tough (after all, they make leather out of animal skin), and it will not split. The body will expand to nearly twice its usual volume, but it will not burst asunder. It expands because the water in the tissues will rapidly turn into water vapour. The air in the gut (about one litre) will expand and cause tummy pain. It will also push the diaphragm upwards, making it harder to breathe, and also putting stress on your heart. The air will rush out of your lungs via your mouth, probably damaging some of the delicate feathery lung tissue. If you foolishly try to hold your breath, bubbles of air will force their way into your blood stream, and then to your brain, causing a stroke. You will also suffer Decompression Sickness (called the "Bends", due to bubbles of nitrogen in the muscles and bones), and lack of oxygen (called "Hypoxia"). By the way, the air pressure on Mt Everest (28,000 feet) is about one third of sea level air pressure - and most untrained people exposed suddenly to that pressure will fall unconscious within six minutes, thanks to hypoxia, or lack of oxygen.
In one case in 1982, a technician testing a vacuum chamber was accidentally exposed to an altitude over 74,000 feet (about 22.5 km) for over one minute. Now the air pressure at 74,000 feet is about 3.6% of the pressure at sea level - in other words, close to zero. When he was pulled out, he was blue in colour, frothing at the lips and bleeding from the lungs. He recovered fully. But there are also cases of people who have been exposed for longer, and who have died.
The scenario in the movie, 2001 - A Space Odyssey is surprisingly accurate. The astronaut, Bowman, has been locked out of the spaceship by the crazy computer, HAL. He bursts into his spaceship by leaping through the vacuum of space from his spacepod, and being exposed to that vacuum for about 10 seconds. It turns out that in a vacuum, you will stay conscious for about 10-15 seconds, and you would survive a 90-second exposure
You would not explode, but you may expand, like a fully-pumped-up Arnold Schwarzenegger.
