Mary-Kate and Ashley Olsen's bid for world domination hit a snag over the weekend. Despite an avalanche of publicity, the wonder twins' much-hyped new comedy, New York Minute, debuted in fourth place with a dismal $6.2 million. Moviegoers instead flocked to Hugh Jackman's big-budget monster mash, Van Helsing, which opened the summer movie season at No. 1 with $54.2 million. Mean Girls, meanwhile, slipped to No. 2 in its second week with $14 million.
