It's official, Liam Neeson is in the business of losing things. In 2008's "Taken, " Neeson's character lost his daughter and it became a bona fide box-office hit! Now, Neeson is having a severe case of identity theft in "Unknown" and the mystery thriller debuted at No. 1 with $21.8 million.

Meanwhile, "I Am Number Four," targeted at our youth market, failed to deliver. The sci-fi flick starring Alex Pettyfer only managed to debut at No. 2 with a less-than-expected $19.5 million.

Disney's re-imagining of the William Shakespeare classic, "Gnomeo & Juliet," remained at No. 3 with $19.4 million. With a long President's Day weekend, No. 2 and No. 3 may switch rankings since "Gnomeo" is only a sliver away from "Number Four." So far, "Gnomeo & Juliet" has raised its total to $50.4 million.
