News Corp.'s (NWS) Avatar is exploding like a blinding supernova at the box office. Although I have no interest in seeing it, I undoubtedly must be one of the only people on the planet who lacks the need to become immersed in the 3-D adventure. According to early estimates at Box Office Mojo, James Cameron's "titanic" cinematic beast scored another $68 million at domestic theaters over the New Year's weekend. Total so far: better than $350 million.

Time Warner's (TWX) take on a famous literary detective had to settle for second place yet again. Sherlock Holmes pulled in $38 million. Coming in third was the Alvin and the Chipmunks sequel, also released by News Corp. Indeed, there's no shortage of excitement at the multiplex.

Shareholders of News Corp. (NWS) are probably happy this Monday as two of the company's films -- Avatar and Alvin and the Chipmunks: The Squeakquel -- did very well over the three-day holiday weekend.

James Cameron's Avatar topped the charts at domestic theaters, pulling in an estimated $75 million, according to Box Office Mojo. If the project can continue to attract moviegoers in large droves, as well as propagate a lot of repeat business, then it should break even before it hits other distribution channels.

The Walt Disney Company (NYSE: DIS) got a nice present today in the form of the nation's number one movie, National Treasure: Book of Secrets.

The sequel to the 2004 blockbuster, National Treasure, National Treasure: Book of Secrets had a monster weekend, with $45.5 million in sales. Nicolas Cage is once again the leading man in this movie, and in this thriller, Cage's character, Ben Gates, is in a struggle to clear the name of an ancestor that has been implicated in the murder of Abraham Lincoln's assassination.

If the first installment of this series is any indication, Disney could be seeing some pretty big numbers from this movie before it is all said and done. When National Treasure debuted in 2004 the movie raked in $35.1 million and ended up with a total of $173 million at the box office.
