After a remarkable four weekends at number one, the reign of The Hunger Games is over.  But you probably saw that coming.  What seems a bit more surprising is the film that is taking its place at the top: Think Like A Man. Until a few days ago, the Sony/Screen Gems comedy looked like it would see a three-day opening in the mid-teens but, on Friday, it drew an estimated $12.2 million from 2,015 locations.  That should translate into a weekend close to $30 million for the Steve Harvey vehicle.  At number two on Friday, The Lucky One is also pulling in bigger-than-expected numbers, though it probably won’t challenge for first place, as was originally expected. The seventh feature from novelist Nicholas Sparks, The Lucky One earned an estimated $9.1 million from 3,155 locations for what should be $25 million by Sunday.  Finally, the latest doc from DisneyNature, Chimpanzee, opened in fourth on Friday with $3.5 million from 1,563 dates – a better start than either African Cats or Oceans… Full details and analysis tomorrow.

On Easter weekend the animated hit Rio managed to hold on to its number one perch for a second weekend in a row with an estimated $26.8 million.  The padding between Fox’s birds and the Tyler Perry’s bawd was pretty slim, however.  In second place Madea’s Big Happy Family was right behind Rio with an estimated $25.8 million.

You know it’s a slow weekend when both wide-release debuts fail to break $13 million. The under performance of The Back-Up Plan and The Losers left room enough for How to Train Your Dragon to take number one with $15 million – the lowest grossing weekend for a top-ranked movie so far this year. It’s doubtful that CBS Films will find a way to doctor those Back-Up Plan numbers by Monday so maybe, just maybe, the slow-to-start 3D Dragon will get to stay on top?

With Disneynature’s Oceans hitting theaters on Earth Day (April 22), we’ve been given 5 clips to help promote the release.  Narrated by Pierce Brosnan and directed by Jacques Perrin and Jacques Cluzaud, Oceans features “spectacular never-before-seen imagery captured by the latest underwater technologies.” At least that’s what the synopsis says.

If you are interested in seeing Oceans, Disneynature will make a contribution to The Nature Conservancy to save coral reefs in honor of every guest who sees the film during opening week (April 22-28, 2010).  So you can go see a movie and feel like you’re saving the planet.  Not a bad deal.  Hit the jump for the clips and more info on Oceans:

“Oceans” and “The Cove” took decidedly different paths on their way to being screened at the 2009 Tokyo International Film Festival (Here’s my first article on the Fest). “Oceans,” from French directors Jacques Perrin and Jacques Cluzaud, a film which is at turns a breathtaking nature documentary and an exhortation to protect the beauty and majesty of the sea, was a natural choice to open the world’s only environmentally minded film festival. “The Cove,” on the other hand, almost did not make the cut despite its previous festival successes, including the Audience Award at Sundance. The film, directed by famed National Geographic photographer Louie Psihoyos, also stresses ecological responsibility but does so by exposing the shady slaughter of dolphins by fisherman in the Japanese fishing town of Taiji.
