Neeson's Unknown Thrills Box Office

Surely January Jones of Mad Men had nothing to do with this big turnout: Liam Neeson scored again with his latest thriller, Unknown, which took in $21.8 million already this weekend, and is expected to round up $26 million by the end of the holiday weekend. The movie was a big hit with adult and senior fans: 89 percent of the audience was over the age of 25, while 54 percent was over the age of 50. The teen sci-fi adventure I Am Number Four (starring dreamboat-to-watch Alex Pettyfer) ran neck-and-neck with Unknown all weekend, taking in $19.5 million. It was a slow President's Day weekend overall, with theater traffic down as much as 30 percent from last year.
