Disney's (NYSE: DIS) new Chronicles of Narnia flick, Prince Caspian, opened on top of the weekend box office to an estimated $56.6 million take at domestic theaters according to Boxofficemojo.com. The media is buzzing with how awful this number is. Well, I'm not sure any of the media outlets I checked actually used the word awful, but I'm using it.

Simply put, the first Chronicles of Narnia movie grossed more than $65 million in its debut weekend, a significantly higher figure than what Caspian captured. Think about this: the first Narnia entry was released in December 2005. Considering that the first film did pretty well, one would have figured that a sequel released a couple years later would have benefited from the high-traffic pre-summer period and that the first weekend would have achieved at least a $70 million+ opening. Never happened. Instead, even though Marvel's (NYSE: MVL) Iron Man fell to number two, its estimated weekend haul of $31 million seems the bigger achievement by comparison.

So, who's to blame here, if anyone? Should Disney CEO Bob Iger be apologizing to shareholders? Maybe a small apology might be in order. I mean, did any of you out there feel the energy of the marketing campaign behind Caspian? I didn't. Once the early Iron Man buzz left the building, Disney should have rushed in to capitalize on the minds of moviegoers who were now waiting for the next big blockbuster coming down the pike; let's face it, during the summer box-office period, that's what we're programmed to do. Even now, I'm looking forward to the business waiting to be done by Viacom's (NYSE: VIA) Indiana Jones and the Kingdom of the Crystal Skull. Disney doesn't have much of a chance to turn Caspian into a super blockbuster if Jones is the hit I think it's going to be. The competition will simply be too much.

At Comic-Con this year, the Walt Disney Company (NYSE: DIS) announced its commitment to make all seven of the Chronicles of Narnia books into feature films, releasing one a year starting in May '08 with Prince Caspian. This decision follows the success of the adaptation of the first book -- The Chronicles of Narnia: The Lion, the Witch and the Wardrobe -- which grossed almost $300 million.

This decision is not surprising, following the conclusion of Disney's Pirates of the Caribbean trilogy, which has no immediate plans to continue. Disney is predictably looking for its next goldmine franchise, and what better to use than a seven book series which already had a successful start?

The only question is whether the quality of production will suffer in the sequels from such an ambitious filming schedule, and after Disney pulled off the Pirates trilogy with such dazzling effects, I doubt that will be a concern -- although the quality of the Pirates scripts did fade down the stretch. At least with these movies, the writers will have a classic source to guide them.
