Last week at this time, I was reporting on the success of Disney's (NYSE: DIS) Race to Witch Mountain, starring Dwayne Johnson, an actor who used to be a full-time grappler known as The Rock for World Wrestling Entertainment (NYSE: WWE). The film opened in the number-one position, taking in $24.4 million.

Well, I'm sorry to say now that the project might not have the best legs in the business. It dropped to fourth place this time around after grossing an amount that, as of early estimates, is over 46% less than what it grossed in its debut weekend.

According to Boxofficemojo.com, the fight for top dog at the domestic multiplex is a close one. Both Bangkok Dangerous, from Lions Gate Entertainment (NYSE: LGF), and Tropic Thunder, from Viacom (NYSE: VIA), have almost the same statistic. Bangkok is estimated to have taken in $7.8 million, while Thunder has approximately $7.5 million to its credit. It will be interesting to see who ultimately takes the honors, but I can tell you that from my perspective, it wasn't a great weekend for Lions Gate shareholders.

The reason I say this is because I thought Nicolas Cage would have brought in more moviegoers. The marketing campaign seemed to predict an opening of well over $10 million. Heck, I would have preferred $20 million considering that the budget on the picture has been reported to be about $45 million. But I must remember that we are no longer in the competitive, fast marketplace of summer. The month of September is certainly more mellow, although that doesn't mean that it can't have a breakout hit.

Sony (NYSE: SNE) came in third with House Bunny, and Time Warner (NYSE: TWX) continues to add to its Dark Knight treasure chest at position number four. Batman now has over $512 million to his domestic credit. Imagine all the upgrades to the Batcave that such an amount of money could finance!

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.
