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.

Whatever mysterious power made those kids run away in Weapons must have also lent some of its black magic to Warner Bros. The studio extended its unprecedented turnaround this weekend with its seventh number one opening of the year.

“ 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.
