Parents need to know that Tusk is a horror comedy written and directed by Kevin Smith, based on one of his own podcasts. The horror part is very gruesome and dark, not unlike The Human Centipede, but with some (supposed) comic relief from time to time. There's lots of blood, some horrific operations, and both physical and emotional torture. Language is very strong, with many uses of "f--k," "s--t," and all kinds of other words. Sexual innuendo and sex talk are also extremely strong, with crude references, sexual situations (including implied oral sex), and a girlfriend in sexy outfits. A main character also smokes a cigarette. This movie has tons of Internet buzz, as Smith asked fans whether they wanted to see it before he made it, and teens may take sitting through it as a kind of dare.
