TV Article Alien and Predator will both win Alien and Predator will both win. The monster showdown will woo boys to the theater; ''Princess Diaries'' will seduce the girls By Dave Karger Dave Karger Senior Writer EW's editorial guidelines Published on August 13, 2004 04:00AM EDT Who knows whether Alien or Predator will win the battle, but the new horror flick ”Alien vs. Predator” will certainly emerge victorious at the box office this weekend. A movie practically tailor-made for the teenage-boy crowd, ”AVP” will have no problem dethroning Tom Cruise from the No. 1 slot with a debut of around $38 million. While the guys check that one out, young girls will flock to ”The Princess Diaries 2: Royal Engagement.” The first ”Princess Diaries” film premiered with $22.9 million three years ago, so look for the sequel to top that figure, opening with about $25 million. Cruise’s ”Collateral,” meanwhile, should dip 45 percent in its second weekend to about $14 million, followed by ”The Village” and ”The Bourne Supremacy” with $8 million each. Also opening this weekend is the film version of the kids’ collectors items ”Yu-Gi-Oh!,” which should manage a $7 million debut. Maybe next time they should think about challenging Alien or Predator to a duel.
