Predator Star Arnold Schwarzenegger Pooped His Pants While Working Out Before Filming

With its dude-heavy cast that includes Arnold Schwarzenegger, Carl Weathers, Bill Duke, Sonny Landham and Jesse "The Body" Ventura, you might not be surprised to learn that the set of John McTiernan's sci-fi/action classic "Predator" was a daily test of macho mettle. The boys went for daily five-mile runs and hit Schwarzenegger's private weight room (which the former Mr. Universe had transported from Los Angeles) for daily workouts that, according to Weathers, apparently descended into muscle-measuring contests.

There was no let-up, especially for the "Predator" star, who felt he had to maintain his Alpha-Dog dominance over his co-stars. However, this prideful drive embarrassingly backfired on Schwarzenegger when he opted to take his customary five-mile run, despite suffering intestinal distress.

Speaking at Beyond Fest in 2017, Schwarzenegger couldn't recall the precise source of his tummy trouble. All he remembered was getting one mile in before he began erupting. The actor explained:

"[W]hen you're in Mexico, you eat the wrong thing and inevitably the s*** hits the fan. So I went on an early morning run, and all of a sudden, I started throwing up. So I tried to be ballsy, wiped my mouth, and continued on running, but then all of a sudden it came out the other side. So I had to quickly run to the side of the road and pull my pants down. I tell you, I was in big, big trouble that day. So it was not five miles that day, it was much, much less than that."

Forcing oneself through a daily workout while suffering from diarrhea isn't particularly smart (that's a good way to incur hypovolemic shock), but it's the kind of moronic display of machismo we expect from a character in a testosterone-soaked action flick. Schwarzenegger's commitment to projecting maximum manliness in his 1980s heyday is what makes films like "Conan the Barbarian," "Commando," "Red Heat" and "Predator" such enduring, endearing classics.

Schwarzenegger's ability to broaden his appeal with comedies ultimately made him more relatable than two-fisted contemporaries like Sylvester Stallone, Jean-Claude Van Damme and Steven Seagal. It's unlikely these guys would ever admit to soiling themselves. Actually, we know for a fact that Seagal is incapable of such candor because he continues to deny emptying his bowels into his trousers after being choked out by martial arts legend Gene Lebell (who has averred on multiple occasions that this did indeed occur). And this is the exactly why Steven Seagal could never be Governor of California.
