Valentine's Day (the movie, not the holiday) stole America's heart this Valentine's Day (the holiday, not the movie). In fact, last week's three new releases settled comfortably into the three top spots for the weekend. Here's the top five:

1. Valentine's Day: $66.86 million
2. Percy Jackson & The Olympians: The Lightning Thief: $38.8 million
3. The Wolfman: $36.5 million
4. Avatar: $30 million
5. Dear John: $18.8 million

Just one new release this week.

Shutter Island
What's It All About:
In 1954 two U.S. marshalls are summoned to an island off the coast of Massachusetts to investigate the disappearance of a murderess from an asylum for the criminally insane.
Why It Might Do Well: Martin Scorsese is behind the camera, hopefully bringing some of the magic of The Departed, Goodfellas or any of a number of great films he has made. Leonardo DiCaprio stars, the trailer suggests a pretty tantalizing psychological thriller, and is giving it 84%. You will also note that there are no other films going into wide release this week.
Why It Might Not Do Well: A nationwide snow storm perhaps? No, I think this one will do quite nicely for itself.
Number of Theaters: 2,500
Prediction: $46 million
