Well, I am sure you have seen this Aintdisablast, Box Office Mojo is predicting Kong to do 58 million and Narnia only doing 32.
Which surprises me that Kong is projected to do so little. I really thought with the hype and word of mouth that this movie would open to bigger numbers.
The only thing I can think of is A.) last true weekend for shopping before Christmas B.) I am so conditioned by the HP and LotR movies that a blockbuster must now have 100 mil openings, that 58 seems like a bad opening.
I will go with B with a little of A thrown in.
