Tonight is the season premiere of Dancing With the Stars, and in anticipation of the big debut, Good Morning America offered a sneak peek behind-the-scenes at the final rehearsals.

Which dancer will be competing tonight with jet lag? Why is one dancer performing tonight with duct tape on her legs? Which dancer has lost seven pounds since rehearsals began? And which dancer is worried about his wardrobe? It's an interesting look behind-the-scenes. Hell, the sneak peek at the Star Wars routine by Billy Dee Williams is worth the look on its own. You can watch the full preview video below:

Dancing With the Stars Season 18 premieres tonight at 8:00 PM ET on ABC.
