After opening with $31.7 million internationally last week, J.J. Abrams' sci-fi sequel Star Trek Into Darkness, featuring Chris Pine, Zachary Quinto, Zoe Saldana, Karl Urban, John Cho, Simon Pegg and more as the crew of the U.S.S. Enterprise and Benedict Cumberbatch as their latest adversary, opened on Thursday in North America. After making roughly $13.5 million in its opening day, it went on to gross an estimated $70.4 million over the weekend. That $83.9 million made over four days is only slightly more than the $79 million the original movie made in its first three days. 

That might seem somewhat disconcerting for a movie that at one point was thought to be one of the $100 million openers of the summer, although it's been doing great international business. So far it's grossed $80.5 million internationally playing in 40 markets which is up almost 80% from the first movie and it's doing 33% better than the reboot with a worldwide total now at $164.5 million. Of its $70.5 million "Star Trek" made this weekend, $13.5 million of that came from 336 IMAX theaters with the draw of Abrams having shot over 30 minutes of footage using IMAX cameras something that's only been done by Christopher Nolan for the "Dark Knight" movies and Brad Bird for Mission: Impossible - Ghost Protocol.

Marvel Studios' Iron Man 3, starring Robert Downey Jr., crossed the $300 million mark domestically on Thursday and then added another $35.2 million over the weekend, down another 52% from the previous weekend. Then again, it's grossed $337 domestically and it just passed the ONE BILLION mark worldwide. It grossed another $40.2 million internationally where it's generally holding stronger and where the $736.2 million grossed overseas has helped bring it to $1073 million since opening last month.
