In the 1981 movie "Outland", starring Sean Connery, there is a scene where a construction worker in space gets a hole in his suit. As the air leaks out, and his body is exposed to a vacuum, we watch in horror through his faceplate as he swells, and explodes.
A somewhat similar scene is in the 1990 Arnold Schwarzenegger movie, "Total Recall." In that movie, Schwarzenegger leaves the pressurized habitat of a Mars colony and begins to blow up like a balloon in the much lower pressure of the Mars atmosphere. He is saved by the creation of an entirely new atmosphere by an ancient alien machine.
