"Rogue One: A Star Wars Story" doesn't hit theaters until December, but thanks to Star Wars Celebration Europe, we've gathered a few tidbits to hold us over.

During the "Rogue One" panel, director Gareth Edwards, ILM Visual Effects Supervisor and CCO John Knoll, and Lucasfilm President Kathleen Kennedy shared some secrets about the highly anticipated movie -- and we're going to share them with you.

1. The idea for "Rogue One" first popped up 13 years ago, during the filming of "Star Wars: Episode III – Revenge of the Sith."

2. The planet of Scarif was filmed in the Maldives. They actually used Maldivian military as Stormtroopers during scenes, but most of them had never even heard of "Star Wars."

3. Darth Vader will be present -- in all his glory -- and he will utter the word "power" at some point, which is expected to send chills down audiences' spines.

4. While it was closed, the crew snuck into the Canary Wharf Tube station in London to film a scene. They wrapped up just before the Tube started running again.

"As we left, they opened the door and everyone wearing suits came in and we were like, morning, morning, morning, and we were desperate to tell them we shot 'Star Wars,'" Edwards said.

5. There's a planet called Jedha, where a few of the characters are found. It's pretty much a desert marketplace that is essentially a Mecca for those who believe in the Force.

"Rogue One: A Star Wars Story" hits theaters December 16th, 2016.
