Thursday night seems to be the winner in movie openings this summer. Pacific Rim and The Wolverine both opened to huge box office pulls during their Thursday night openings this July, and now the new action flick with Denzel Washington and Mark Wahlberg has joined the list, earning $1.3 million in North American ticket sales. Still at the top of the box office list for this week is The Conjuring, Despicable Me 2, and Turbo. The Smurfs 2 also comes out this weekend. 2 Guns is expected to gross a total of $20 million in North America this opening weekend.
