For one night at least, anarchy reigned.
"The Purge: Anarchy," Universal's horror thriller about a future United States in which all crime is legal for 12 hours, topped the Friday box office with $13 million.
Though a solid number for the $9-million movie, it's below the performance of the first "Purge" film, which opened last June to $16.8 million on Friday.
"The Purge: Anarchy" is expected to lose the weekend to 20th Century Fox's science fiction reboot "Dawn of the Planet of the Apes," which collected $10.45 million Friday in its second week of release. "Apes" is projected to swing through the weekend with about $35 million, while "The Purge" isn't expected to top $30 million.
In the No. 3 position, Disney's animated sequel "Planes: Fire & Rescue" grossed $6.3 million Friday, putting it on track to come in at a middling $17.5 million for the weekend.
Last among the new films in wide release was Sony Pictures' R-rated comedy "Sex Tape." The film starring Cameron Diaz and Jason Segal grossed $5.6 million Friday, putting it on pace to collect about $15 million for the weekend.
