Zac Efron decisively ditches his squeaky clean High School Movie persona for one as a red-blooded horndog with this week's That Awkward Moment , an R-rated adventure in the grand tradition of '80s sex comedies. That Efron's latest can't hold a candle to those hormonally charged classics isn't an enormous surprise, since as the past two decades have shown, making a boisterous sex romp takes more than just a handful of pimply actors and some women eager to flash their wares for the camera. With GIFs, naturally. Ivan Reitman and Bill Murray's movie careers were jumpstarted by this gem, in which Murray stars as the head counselor at a low-rent summer camp, where he mentors — and is aided in his own quest for love by — a lonely nerd. Though not quite as out-and-out raunchy as its sequels the best of which is Meatballs III , it's nonetheless an amusingly juvenile slice of sex-charged silliness. Headlined by three Playboy Playmates — and Danny Bonaduce!
