Well, I knew I Am Legend was going to do well, but HOLY TOLEDO! Will Smith's apocalyptic science fiction/horror flick set a record for a film opening in December, an honor previously held by 2003's The Lord of the Rings: The Return of the King. Alvin and the Chipmunks also found its niche, pulling in some righteous bucks of its own. As you can see, the gap between these two and the holdovers from previous weeks is quite dramatic. Here are the final numbers:

I Am Legend $76.5 million.
2. Alvin and the Chipmunks$45 million.
3.The Golden Compass$9 million.
4.Enchanted$6 million.
5. No Country for Old Men$3 million.

We've got a whopping five big releases this week, with three of them using colons in the titles. That must be a record right?

Charlie Wilson's War
What's It All About: Tom Hanks plays Charlie Wilson, a real life congressman who sought to aid Afghani rebels fighting off Soviet soldiers during the 1979 invasion.
Why It Might Do Well:
As the TV spots are touting, this one has five Golden Globe nominations and some strong critical buzz working in its favor (83% Fresh over at Rottentomatoes.com). With bankable stars in front of the camera like Hanks, Julia Roberts and Phillip Seymour Hoffman and Mike Nichols at the helm, what's not to like?
Why It Might Not Do Well: There's some serious competition out there this week from both newcomers and last week's two big releases. Also, a film dealing with politics may not be what people are looking for in a holiday movie.
Number of Theaters: 2,500
$15 million

National Treasure: Book of Secrets
What's It All About: Nicolas Cage returns as Ben Franklin Gates, the globe trotting artifact hunter who must now track down pages of John Wilkes Booth's diary to clear his family's name.
Why It Might Do Well: The first National Treasure movie opened to a respectable $35 million weekend in 2004 before going on to make $173 million domestic and $347 million worldwide, so I bet a lot of folks who liked the first will be back for more. This one opens in way more theaters than anything else coming out this week and I suspect this will be next week's number one movie.
Why It Might Not Do Well: It depends on how many people are willing to forget Ghost Rider.
Number of Theaters: 3,500
$55 million
