I'm going to refrain from overloading today's box office report with too many telephone puns and just report the fax: Colin Farrell's new thriller Phone Booth, which was put on hold as a result of last fall's real-life sniper crisis, got a ringing endorsement from moviegoers over the weekend, dialing up $15 million to debut at No. 1. Amanda Bynes's teen flick What a Girl Wants opened in second place with $12.1 million, followed by Vin Diesel's latest action saga A Man Apart (No. 3 with $11.2 million). Last weekend's top movie, Head of State, dropped to fourth place with $8.8 million.
