In Henry-Alex Rubin’s “Semper Fi,” men are men, women are props and brotherhood — whether literal or figurative — is everything.

Virtually sweating testosterone from every frame, the movie follows five longtime friends as they bicker, drink and roughhouse their way through a story that purports to be about honor and is really about stupidity. At its center is Cal (Jai Courtney), a stiff-jawed police officer and, like his friends, a Marine Corps reservist. When not bowling, boozing or playing weekend warrior, Cal is pulling his younger half brother, Oyster (Nat Wolff), out of scrapes. A numbskull with a gigantic chip on his shoulder, Oyster can barely walk the length of himself without picking a fight.
