Parents need to know that the film includes assorted violent acts, exaggerated for comedy, such as stabbings, shootings, collisions, car crash, seppuku, a hit to the crotch, running into trees and a building, boxing, necks breaking, Mike Tyson lookalike biting off ears, vehicles and shipyard containers slamming into people, alien tripods zapping people into electricky dust, and U.S. military blowing things up. Tom hits his daughter with suitcase, slams her head in car door, and leaves her outside to be zapped by aliens. Saw spoof includes saw to cut off leg, knife to cut out eyeball, toothy torture helmets, and other mechanical threats. Very little blood visible throughout the film, exaggerated sound effects for breaking bones, some screams of comedic terror. At film's end, Tom ("the man who saved the world") appears on Oprah, where he eats the sofa, punches Oprah (she punches back), smashes her with a chair, breaks her hands, and generally destroys the set. Characters drink vodka and beer; characters refer to "weed." Characters make sexual references (language and some images, with immature joking about nakedness and genitalia). Lots of profanity. In the context of not liking kids, the president says, "Remind me to sign that abortion bill."
