J.J. Abrams Star Trek Into Darkness debuted this weekend raking in $165.5 million worldwide.
The number, while not too shabby, is less than Paramount appears to have anticipated and just about the same as the 2009 Star Trek movie.
For Friday, Saturday and Sunday, Star Trek Into Darkness made around $70 million domestically; however, the movie technically opened on Thursday as Paramount - at almost the last minute - gave the green light to open a day earlier.
So if you add the Thursday numbers with the Wednesday midnight openings, the total in the U.S. comes to around $84.1 million, which is shy of the $100 million estimate by Paramount.
2009's Star Trek saw it's first three days come in at $75.2 million (U.S), with it's four day total around $86.7 million (U.S.).
However, bear in mind that the 2009 movie didn't have the added benefit of IMAX and 3D; Abrams shot Star Trek Into Darkness in part using IMAX cameras.
Also to be considered is inflation.
Where the difference between the two is seen is the international box office as Star Trek Into Darkness is doing 33% better, which may in part be due to Paramount's heavy promotion of the film overseas with 20 minutes of footage and such.
Speculating as to why the box office results weren't as expected: It's thought a competitive month of May with Iron Man 3 and The Great Gatsby opening may have had something to do with it as the film is receiving favorable reviews and the audience CinemaScore is an "A."
