What can you expect from 'Glee: The 3D Concert Movie'? Backstage antics, the songs you've come to love (or loathe) and lots of ribbons flying in your face!

The new 'Glee' flick hits theaters Aug. 12 for two weeks only. Shot during this summer's live tour, the movie will give fans a glimpse of what goes on backstage as the actors prep to perform to sold out arenas.

'Glee' returns to Fox on Tues., Sept. 20 at 8PM. Season 3 will be the last for many of the main characters. Co-creator Ryan Murphy has confirmed Lea Michele, Chris Colfer and Cory Monteith will be among the characters to say goodbye. Perhaps to headline their own spin-off? Time will tell.

Watch the trailer for the new concert movie below.
