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' debuted at $42.5 million, while 'Freakier Friday' premiered to $29 million. Reigning box office champ - 'Fantastic Four: First Steps' fell to third place during its third weekend. "Bad Guys" and "The Naked Gun" round out the top five.

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.
