Fortunately, overkill is what Jason Friedberg and Aaron Seltzer do best: as the uncontested titans of the parody genre (with fingers in everything from the franchise to the more recent ) they continue to prove that ridiculing other movies is much easier than making your own. In King Leonidas (Sean Maguire, whose accent veers from London to Glasgow and back again) and 13 faithful boyfriends — er, soldiers — face off against the Persians and an avalanche of pop-culture detritus. While a slutty Queen Margo (Carmen Electra, of course) tries to distract the men from one another, celebrity not-so-lookalikes and unfunny reality-show takeoffs vie for our attention and gag reflex. As redundant and tasteless as Queen Margo’s crab-infested chastity belt, “Meet the Spartans” is best described by the reactions of a row of what appeared to be sixth graders who shared the screening with me.
