Early today (Monday) box-office trackers Media by Numbers noted that Under the Sea , which was screen over the weekend on just 49 IMAX screens debuted with $857,000 -- amounting to a per-screen average of $17,490. "Whether it be the wide releases or smaller ones like this, IMAX continues to impress," Paul Dergarabedian, president of Media by Numbers, commented. "Often we fixate on the top of the box-office chart, but sometimes there is a lot of action for the films in fewer theatres that are making their mark."
