What parents need to know
Parents need to know that World's Greatest Dad is a very dark comedy about a father who inadvertently profits from his teenage son's accidental death. There's strong language (words like "f--k" and "s--t" are said in nearly every scene), and the sexuality is rampant -- especially in early scenes. The teenage boy is a porn aficionado, and he constantly talks about explicit sexual acts, masturbates to magazines (and other stimuli), and even tries auto-erotic asphyxiation. There's only one actual sex scene, but star Robin Williams' naked body is briefly shown in another scene. In comparison to the sex and language, the movie's violence and substance use are ather mild, although an adult does smoke marijuana and allows an underage friend to eat a pot brownie.
