Hollywood's box-office slump continued into an 11th week as Ridley Scott's Crusades epic, Kingdom of Heaven, debuted at No. 1 over the weekend with a disappointing $20 million. Paris Hilton's horror pic, House of Wax, opened at No. 2 with a tepid $12.2 million, followed by The Hitchhiker's Guide to the Galaxy (No. 3 with $9.13 million), Crash (No. 4 with $9.1 million) and The Interpreter (No. 5 with $7.5 million). Industry watchers expect the multiplex funk to end on May 19 with the opening of George Lucas' little indie Star Wars: Episode III Revenge of the Sith.
