John Carpenter's "The Thing" in addition to being one of the finest horror movies ever made is a great example of a gory monster movie. The monster is incredibly scary in part because of the way it replicates its victims, who have a penchant for escaping captivity in increasingly bloody and disgusting ways. If you're in the mood for more of that kind of gory monster action, here are four gory monster movies like "The Thing." Check one of them out the next time you want to see what people's insides look like.

"Alien" The monster in "Alien" doesn't just want to kill you. It wants to invade your most private space, impregnate you, and leave you to be killed by the offspring's "birth." As you might imagine, "Alien" contains one of the most famous instances of gore in monster movie history, as a small alien "chestburster" uh, bursts out of John Hurts chest, causing a bloody mess that's so shocking, audience members were said to faint during the movie's 1979 release.

"The Fly" Seth Brundle just wanted to teleport from one place to another. Unfortunately for him and his loved ones, his teleportation chambers had one crucial design flaw: If two things got transported together, they ended up physically and genetically fused into one. The result is even gorier than you might expect, as Brundle's human form decays away, leaving a horrifying human/fly hybrid in its place. Oh, and there's a scene where he regurgitates acid and uses it to eat away some other guy's hand. Now that's monster gore.

"Invasion of the Body Snatchers" While not as explicitly gory as "The Thing," the '70s version of "Invasion of the Body Snatchers" has plenty of gore to go around. The most disturbing image in the movie is undoubtedly a dog with the face of a man, which is one of the most unsettling special effects of all time. Not to mention all the half-formed pod people.

"Mimic" Guillermo del Toro has never been one to shy away from gore, and his homage to monster movies like "The Thing" and "Alien" is no shrimp in this department. Most of the gore involves people getting devoured by a giant insect (or insects). And the grimy atmosphere that should be familiar to fans of del Toro's does nothing to ameliorate the gore.
