DreamWorks bigwigs can keep their hats on – Shrek Forever After, the supposed final entry into the Shrek franchise, opened pretty well. With $71.3 million now stashed away, the animated flick managed to outsource 2001’s Shrek but was unable to score profits in the triple-digit range the way predecessors Shrek the Third and Shrek 2 did. After Solitary Man’s $22,250, Shrek had the highest per-screen average at $16,345. Knocking How to Train Your Dragon off 869 screens (but still remaining in the top ten), Forever After boasted a decent-enough sum if you ask me. I wouldn’t declare it a disappointment but I also can’t say it’s all too impressive; more like expected. MacGruber’s weekend bow was buzzed about yet had zero chance of topping Shrek. Its only real competition was Iron Man 2, which dropped 48.9% to #2 after staying on top for two weekends. Jon Favreau’s blockbuster grossed $26.6 million, already sacking $251.3 million three weeks out.

Surprisingly enough Robin Hood had a slightly lesser stoop than Iron Man did. Ridley Scott’s period piece about the notorious medieval thief fell 48.1% after opening to $14.9 million less than the aforementioned summer epic. The movie made $18.7 million, a total of $66.1 million in ten days. Hear me out; I still say this is one that will soon be forgotten by most and left to die. Summit’s Letters to Juliet, starring Vanessa Redgrave and Amanda Seyfried, dove a steady 32.8% at #4 clutching $9.1 million. Total: $27.4 million on a budget that has yet to be officially released.

Fox Searchlight’s Just Wright tacked another $4.2 million to its ten-day haul of $14.6 million at 1,831 sites.

Out of the top five-

• Universal’s MacGruber was the biggest let-down, grossing a mere $4.1 million after summoning only seven-digit numbers all weekend. Nix It’s Pat and Stuart Saves His Family, Will Forte’s action spoof currently holds the lowest opening for an SNL sketch-to-screen adaptation. Couldn’t even top the last Lorne Michaels-produced comedy Baby Mama, which was released in April 2008, or Hot Rod’s measly $5.3 million debut. After premiering at the South by Southwest film festival a few months ago MacGruber was shining a 100% fresh Rotten Tomatoes score. As of Friday it’s been demoted to 54% rotten. I wish I could have made it out this weekend and brought friends to see it. Despite everything that the movie has gone through it remains a must-see.

• Anarag Basu’s Kites played to #10 with $1 million at 208 sites.

• Soderbergh vets Brian Koppelman and David Levien saw Solitary Man, starring Michael Douglas and Jesse Eisenberg, to the beat of $89,000 at four areas.

• Racing Dreams, which I believe is being remade for the States crowd, drummed up $21,500 at 33 sites.

• Documentary After the Cup: Sons of Sakhnin United grossed $3,300 at one site.
