With reasearch suggesting that 20-25% of movie audiences avoided going to the theatre this weekend, box-office business was slower than normal for this time of year.  Still, The Dark Knight Rises retained its dominance in North America.  Over the Friday-Sunday period, the film added $62,101,451. In just 10 days of release the film has collected $287,112,810. Overseas, the seventh installment of the Batman film franchise added approximately $122,100,000 this weekend.  In 10 days the overseas total now stands at $248,200,000.  Worldwide “The Dark Knight Rises” has amassed over half a billion dollars, bringing in a total of $535,312,810.
