Not much of a surprise Iron Man 2 is on top its second weekend. No way is a movie that opens to $133.6 million being kicked to #2 only ten days out. Jon Favreau’s epic nearly massacred Ridley Scott’s Robin Hood by grossing $53 million, slipping 59% from last weekend. I’d count it as a win nonetheless. Sir Robin of the Hood was obviously expected to do extremely well after its reported budget of over $200 million was released last week. Iron Man 2’s complete domestic total is $212.2 million, foot just out the summer door. Good luck with Robin Hood having much holding power, Universal. The flick’s only competition next weekend is Shrek: The Final Chapter but come on. No doubt a lot of Iron will be gracing the charts for weeks to come.

Being sold as some type of sequel to Gladiator, Robin Hood’s $37.1 million does indeed stack up in a manner of speaking. Gladiator only made $187.7 million its entire domestic run; however it detained a cult following since its release in 2000. Still, the medieval Russell Crowe-starrer’s 44% RT consensus couldn’t have helped get behinds in seats any. Nor could the fact it was intended to begin production in 2007. After Scott’s Body of Lies failed to generate hype or your money love, Robin Hood was supposed to be his next American Gangster ball-buster. After we all realized it was not, word-of-mouth must have killed the action/adventure. Too bad?

Summit’s debut Letters to Juliet, starring Amanda Seyfried as a writer who stumbles upon an unopened love letter lost for years, bowed in third with $13.8 million at 2,968 play sites. Upon seeing director Gary Winick’s previous effort Bride Wars I didn’t have much expectation for a movie that reveals its complete plot summary in the trailer. But hey, I hear it’s good for what it is. Could have holding power amongst fans of Mamma Mia!

Sanaa Hamri (don’t ask me to pronounce that) brought Just Wright to 1,831 areas and made a decent $8.5 million, with a per-screen average inching Letters to Juliet’s. Hamri’s only other movie is 2008’s Sisterhood of the Traveling Pants 2, which opened to $5.7 million. And would you believe Just Wright had the highest RT rating of any movie in wide release this weekend?

How to Train Your Dragon fell 23% to #5 clutching $5.1 million from this weekend and $207.8 million from every other since March. No need to further gush on this movie’s success.

Out of the top five-

• First-time director Marc Forby’s Princess Kaiulani, about royalty trying to fend off U.S. manifest destiny, came to $184,750 at a single site.
• Last year’s Cannes runner Daddy Longlegs started with $8,900.
• IFC’s Looking for Eric held $7,500.
• Dark comedy The Living Wake, starring Jesse Eisenberg, debuted with $4,800. Weird this played at CineVegas in 2007 and is only in national theaters now…
