While James Cameron's first film in 12 years did solid business on opening weekend, it seemed it did even better than first thought. According to Variety, Avatar's posted a bigger Sunday at the box office than originally expected, and the film's opening weekend take now stands at $77.3 million.

If the numbers hold up, the film will have broken the record for a December opening weekend, just edging out the 2007 film I Am Legend, which took in $77.2 million on its opening weekend. It was originally reported here yesterday that Avatar took in an estimated $73 million on opening weekend.

James Cameron's Avatar opened in 3,452 theaters this past weekend, with 2,052 theaters playing the film in the 3D format.
