New Line's horror pic and Disney's family comedy delivered a double win for the late summer box office, as well as a victory for two challenged genres.

“ Weapons ,” a twisty horror film about a group of missing children, and “ Freakier Friday ,” a body swap comedy, delivered a potent one-two punch at the box office this weekend, lifting ticket sales as summer movie season draws to a close.

"Weapons," a new horror film about the mysterious disappearance of a group of children from the same school class, opened atop the North American box office.
