Looks like the Jonas Brothers weren't up to pulling in the numbers Hannah Montana did last year around this time, allowing Tyler Perry's Madea Goes to Jail to hold on to number one despite a 60% drop from last week. Slumdog Millionaire continues to do well because of all the Oscars, not to mention its tacking on 700 additional screens didn't hurt. Street Fighter: The Legend of Chun-Li landed in eighth place with $4.7 million. Here's the top five:

1. Tyler Perry's Madea Goes to Jail: $16.1 million
2. Jonas Brothers: The 3D Concert Experience:$12.5 million
3. Slumdog Millionaire: $12 million
4. Taken: $9.9 million
5. He's Just Not That Into You: $6 million

Only one release this week, but it's a doozy.

What's It All About:
Based on the groundbreaking graphic novel by Alan Moore and Dave Gibbons, Watchmen takes place in an alternate version of 1985 in which Richard Nixon is still the president and costumed heroes have been part of American culture since the 1930s, but have been outlawed for the last several years. An investigation into the death of a masked adventurer called The Comedian uncovers a dark secret that threatens the world.
Why It Might Do Well: Director Zack Snyder's last feature, 300 (which was also based on a comic book) had a $70 million opening weekend, a total domestic gross of $210 million with $456 million worldwide. As of this writing the film is getting a 73% fresh rating on Rottentomatoes.com.
Why It Might Not Do Well: People who suffered a traumatic experience during a performance of Blue Man Group should probably stay away (not only is Dr. Manhattan blue, but he's frequently naked), but I doubt that will include enough people to affect the box office take.
Number of Theaters:
$70 million
