Twelve years after Titanic, James Cameron once again has the number one film in America, with his science fiction epic Avatar making more money than all other films in current release combined. Things weren't quite as rosy for the romantic comedy Did You Hear About the Morgans? Here's the top five:

1. Avatar: $73 million
$77 million
2. The Princess and the Frog: $12.2 million
3. The Blind Side: $10 million
4. Did You Hear About the Morgans?: $7 million
5. The Twilight Saga: New Moon: $4.4 million

We've got three new contenders as we go into the Christmas weekend with two flicks going into wider release.

Alvin & the Chipmunks: The Squeakquel
(on Wednesday)
What's It All About: Those furry little CGI crooners are back for more. This time they're entering a singing contest to save their school's music program, though they face stiff competition from a trio of female singing chipmunks.
Why It Might Do Well: 2007's Alvin and the Chipmunks had a $44 million opening weekend, and let's face it, these guys have the cute going on.
Why It Might Not Do Well: It's still early but is giving this a paltry 22%.
Number of Theaters: 3,700
Prediction: $39 million

It's Complicated
What's It All About:
Comedy starring Meryl Streep who plays a woman who begins an affair with her remarried ex-husband played by Alec Baldwin.
Why It Might Do Well: A romantic comedy makes a good counter programmer for this week's other newbies. The cast, which also includes Steve Martin should be a big draw.
Why It Might Not Do Well: Why? Well, it's complicated.
Number of Theaters: 2,800
Prediction: $22 million
