'Glee: The 3D Concert Movie': Watch the trailer, Harry Shum's ab flash

Lea Michele, Chris Colfer and Cory Monteith may not be long for the "Glee" world, but FOX is certainly making the most of the original cast while it has them.

"Glee: The 3D Concert Movie" opens worldwide on Aug. 12, 2011, and Apple has released the first official trailer (via Movieline).

Filmed during the June 16 stop in East Rutherford, NJ, the movie includes the set list from the recent tour and a few special additions --- like Gwyneth Paltrow, who makes a cameo with her cover of "Forget You."

So what else can we expect from the "Glee" movie? From the looks of the trailer... Lea Michele's showboating, Harry Shum's exposed abs, failure to distinguish characters from the actors who play them and Darren Criss' general adorableness.
