“New Moon” fans seemed to spend this week pitching tents outside theaters instead of viewing the Summit pic’s online trailer.The highly anticipated vampire sequel spent its final pre-release session at No. 1 on Visible Measures’ Top 10 online film trailer chart with an 11-week total of nearly 20 million views. However, this frame saw only a 9% increase in views. Sony’s “2012″ not only survived its opening, but the disaster pic’s online trailer continues to thrive. With Visible Measures now tracking post-release week stats, “2012″ is at No. 2 in its 12th week on the chart with a 42% increase in views to finish with just over 13 million views. The post-release tracking could be an accurate indicator of potential second-weekend box office receipts. If that is the case, then “2012″ is in for another wild ride. One animated Fox film took a small dive this week while another took a gigantic leap. “Avatar” dropped 7% but still remains at No. 3 with 1.2 million views, while “Alvin and the Chipmunks: The Squekquel” jumped a whopping 144% to reach over 856,000 views and push “Ninja Assassin” to fifth place. Disney’s “Old Dogs” is new as the Robin Williams-John Travolta starrer entered the chart at No. 7 with one week until release. Also of note: Lionsgate’s “Brothers” moved up from eighth to sixth place; Sony’s “Planet 51″ held steady at No. 9; TWC’s “The Road” dropped from No. 7 to No. 8 despite a 25% increase in views while Warners’ “The Blind Side” fell from sixth to tenth with a 5% drop in views.
