As Seen In: Total Recall (1990)
There's a reason why humans don't exist on Mars, and it has to do with a little thing called "air."
Allow the evil Vilos Cohaagen (Ronny Cox) to demonstrate what we mean. As Total Recall draws to a close, the heroic Douglas Quaid (Arnold Schwarzenegger) finds a way to sends himself, Cohaagen, and Melina (Rachel Ticotin) hurling out into the Martian atmosphere, which isn't fit for human lungs. Quaid and Melina manage to get back indoors, but Cohaagen, as you can see here, chokes to death while the decompression puffs his cheeks and bulges his eyes. Looks uncomfortable.
