Star Trek Into Darkness opens on 3,760 screens tonight (Thursday) after a Wednesday preview on 336 IMAX screens only, where it grossed an estimated $2 million. (The IMAX version features about a half hour of footage that was shot with 70mm IMAX cameras, although some moviegoers are making a ruckus online that many new IMAX digital screens are not much larger than conventional screens.) Box office forecasters figure that the movie, which has received mostly solid reviews, will pass the $100-million mark before the weekend is over. (The film is supercharged with some spectacular special effects and little of the philosophizing about the future that Gene Roddenberry integrated into his original Star Trek episodes.) No other film is opening against it.
