I also have read the tracking estimates of around $60 mil. I think it will outperform those estimates but probably come in less than Wolverine. I am guessing $76-81 million dollar range.
The second weekend will tell the tale. We will know then if this film has broadened the appeal of Star Trek or is just drawing the core audience of fans.
Based on the glowing reviews from Trekkers and Non Trekkers alike it has a very good chance of having an extended run based on word of mouth recommendations.
