Gleeks, Christmas has come a little early this year. It's hard to be critical of a 'Glee' Christmas episode, especially when everyone always looks so cheerful.

It's time to put up the tree, wrap the gifts, and dance around with some garland. Now that the Troubletones are no more, the entire glee club is back together this holiday season to help deck the halls at McKinley. Not only will New Directions get a chance to be featured in a holiday special, but they'll also be joined by a very special guest -- Chewbacca!

"[Chewbacca] makes an appearance into Artie's dream in a way," Shum told AOL TV. "I can't really delve into the details, but it's something to do with Artie."
