Overall, the US Box Office was up 100% on last weekend's gross.

With Christmas Day falling on Friday this year, the weekend box office saw a mammoth increase in ticket sales with the general public taking advantage of the holiday Friday. Many films registered big grosses, both new and returning films.

Our number one film is the 3D hit AVATAR, which managed to take out top spot for a second weekend in a row while only losing 1% of its audience. The film earned a fantastic $75.6 million and has now earned $212.7 million domestically.

Not to be outdone was Guy Ritchie's new film SHERLOCK HOLMES which managed an excellent $62.3 million over the weekend to land in second place. Reviews and reception were better than expected and will likely continue to do great business.

ALVIN AND THE CHIPMUNKS: THE SQUEAKQUEL cemented itself in third spot with a strong $48.8 million over the weekend, and solidifying this franchise for some time to come.

Fourth place goes to the counter-programmed film IT'S COMPLICATED, which earned a very good $22.1 million on opening. The Meryl Streep-Alec Baldwin-Steve Martin rom-com did quite well in face of all the strong competition.

Being the last official weekend for the year, the box office went out with a bang, and is likely to start the new year with a bang given New Year's Day also falls on a Friday.

The Top 12 at the US Box Office took in a total of $259,923,186 for the whole of the weekend 25-27 December 2009.
