The first of three Friday-the-13th weekends this year (that hasn't happened since 1998) is not auspicious for the box office. Several analysts are predicting that the box office, which has been on a hot streak since the beginning of the year, is likely to cool off. All three movies opening this weekend are receiving either negative or ho-hum reviews. Given the day on which it's opening and it's title, the latest Friday the 13th movie is likely to top the box office, with analysts predicting a take of $15-20 million. Confessions of a Shopaholic , they say, is likely to come in a close second, given the surprising performance of female-oriented movies of late. Finally, The International, a thriller dealing with corrupt international bankers is likely to make a decent showing if for no other reason than that people are prepared to boo corrupt international bankers these days.
