TV Article J. Lo and J. Fo will deliver a ''Monster'' hit J. Lo and J. Fo will deliver a ''Monster'' hit. ''Monster-in-Law'' will easily knock ''Kingdom of Heaven'' from the top spot By Dave Karger Dave Karger Senior Writer EW's editorial guidelines Published on May 13, 2005 04:00AM EDT With Kingdom of Heaven‘s disappointing U.S. debut last weekend, it’s now up to Jennifer Lopez and Jane Fonda to kick-start the summer box office. The duo’s new comedy, Monster-in-Law, hits theaters this weekend, much to the delight of women and gay men everywhere. The combination of its guilty-pleasure plotline (woman and potential mother-in-law hate each other) and Fonda’s return to the big screen should result in an opening of $25 million. Also premiering this weekend is Will Ferrell’s latest silly comedy Kicking & Screaming, in which he plays a crazed soccer dad. Fans of his unique brand of humor will turn up to the tune of $16 million. Kingdom of Heaven, meanwhile, will see a 45 percent drop to $11 million, followed by the new Jet Li-Morgan Freeman thriller Unleashed with $9 million. Fifth place will go either to House of Wax or the long-delayed Christian Slater action flick Mindhunters, each of which should gross $6 million this weekend. Oh, Star Wars, where are you when we need you?
