Weekend box office: 'Megamind' -- blue man's coup

A blue, big-headed villain dominated the box office, Robert Downey Jr. and Zach Galifianakis took a semi-lucrative road trip and Tyler Perry's latest didn't do the usual Tyler Perry business.

The details on those developments, as well as a strong debut for "127 Hours," in the weekend box office rundown.

As expected, the kid-friendly superhero satire "Megamind" easily shot to the No. 1 spot with a healthy if not staggering $47.6 million; that opening was heftier than the one for "How to Train Your Dragon" ($43.7 million) but a bit less than the one for "Despicable Me," ($56.3 million) which, to be fair, came out in the heart of summer blockbuster season. The performance also pales when compared to the usual Pixar debut; the most recent adventure from that studio to open smaller was 2007's "Ratatouille," which cooked up $47 million in its initial weekend of release.

"Megamind" -- which, according to Box Office Mojo, opened more widely in 3D than any previous release -- still has a ways to go to make back that $130 million budget. But since the next high-profile family-friendly releases, "Harry Potter and the Deathly Hallows Part 1" and Disney's "Tangled," don't start arriving for another two weeks, "Megamind" should be able to keep a lock on the moviergoers-with-mommys-and-daddys market.

"Due Date" -- the latest comedy from "Hangover" director Todd Phillips -- set one of those obscure records that only a box office geek could care about: it scored the biggest opening for an R-rated November release ever! (Try fitting that on a poster.)

Meanwhile, "For Colored Girls" opened with $20.1 million, less than what we usually see for a Tyler Perry movie. But this particular Tyler Perry movie was missing a few key ingredients: Perry's name in the title, a sense of humor and Madea. Of course, the play that inspired the film is certainly well-known, but perhaps that wasn't enough to inspire a sense of urgency about catching the film in its first weekend.

"127 Hours" -- the story of a terrible hiking mishap that eventually leads James Franco (in the role of Aron Ralston) to cut off his own forearm -- only opened in four theaters. But it managed to bring in $266,000, or an average of $66,500 per screen. That bodes well for its wider release this weekend.

So can "Megamind" remain on top? Or will sci-fi thriller "Skyline" or Denzel Washington's "Unstoppable" bump it down a notch or two? Make a prediction by casting a vote in our poll.
