See the Trailer for the Cory Monteith Tribute Episode of 'Glee'

Glee has released a trailer for next week's episode, which serves to memorialize Cory Monteith, as well as his character Finn. The clip pairs Lea Michele's cover of "Make You Feel My Love" with some pretty devastating shots of the cast mourning. "Almost everything in that episode is from the first take of every performance, because the actors and the crew had a really hard time shooting it. I’ve never seen a crew where you can’t continue shooting because they left the room sobbing," series creator Ryan Murphy said of the episode. "It was very hard, and I struggled even working on it, because you’re seeing what they felt about not just Finn, but Cory. So I think it’s amazing performances across the board, and everybody went into it with a lot of love."
