The ComingSoon.net Box Office Report has been updated with studio estimates for the weekend. Be sure to check back on Monday for final figures based on actual box office. This was a weekend for writer/directors to shine, but while there was a lot of star power on display in many of the new movies, it was the latest from playwright/mogul Tyler Perry that was able to bring in the biggest audience of his female African-American fans to see his third movie as a director, Tyler Perry’s Why Did I Get Married? (Lionsgate). Featuring the return of Janet Jackson to the big screen for the first time since 2000’s Nutty Professor II: The Klumps, Perry’s latest play-turned-movie grossed an estimated $21.5 million its opening weekend in just 2,011 theatres, fewer than his previous two movies. Tony Gilroy’s corporate thriller Michael Clayton (Warner Bros.), starring George Clooney, came out just ahead of James Gray’s third film, the police drama We Own the Night (Sony) starring Joaquin Phoenix and Mark Wahlberg, both which ended up with roughly $11 million. Neither of the two new movies from respected writer/directors was able to keep The Rock’s family film The Game Plan (Disney) from having a third strong weekend, dropping to #2 with $11.6 million.
