The Thing (1982)

Parents need to know that this movie is graphically violent, gory, grisly, and frightening, though it's so over-the-top and dated that the gore is almost campy. Humans and dogs are the victims of monstrous alien beings attempting to destroy them. They are hideously ugly creatures with slimy tentacles, pulsing muscles, jagged teeth, and screeching howls. They imitate other life forms and take over living beings suddenly, turning a beautiful dog into a raving, slathering beast, or a man into a giant, multi-limbed, oozing mass of pus and muscle. The movie has occasional swearing ("f--k," "ass," "d--k," "s--t,") and the leading man drinks whiskey straight from a bottle several times, others drink occasionally, and one character smokes a marijuana cigarette.
