Audiences wanted to unravel the mystery of Unknown over Presidents' Day weekend. The thriller, starring Liam Neeson and January Jones, topped the box office with $21.8 million, while I Am Number Four, another action-packed new release, trailed behind it in second place with $19.5 million.
Gnomeo and Juliet came in the third spot, as it did last weekend, with $19.4 million, beating out last week's box office champion, Just Go With It, which pulled in $18.2 million. Finally, fifth place was taken by Martin Lawrence's comedy Big Mommas: Like Father Like Son with $17 million. Surprisingly, it edged out Justin Bieber's documentary Never Say Never, which was so close to the top spot at the box office last weekend, but only charted in sixth place this week.
