London - "Star Wars" Celebration this year is in high gear, and unveilings of some juicy details about the upcoming Star Wars prequel, Rogue One: A Star Wars Story is hurled left and right. The Rogue One panel gathered last Friday. The panel includes director Gareth Edwards, and Rogue One stars Felicity Jones, Mads Mikkelsen, Forest Whitaker, Diego Luna, Alan Tudyk, among others.

The Rogue One panel started with the classic floating text introduction from Star Wars: Episode 4 A New Hope, but is then interrupted right at the very end - a scrambled audio and some flickering visuals followed right after. Then, the Rogue One logo is finally shown. The discussion about the movie followed, and it one point in the discussion, the audience may have heard a juicy spoiler.

The is confirmation that Darth Vader will be included in the movie, but as to how much will be used in the film is still unknown. However, fans are delighted to learn that his original voice actor, James Earl Jones will return to voice Darth Vader again. Aside from these details, not much has been said about Vader.

Also in the discussion are the two new planets that they will be introducing in Rogue One. The first planet is named, Scarif, while the second one is known to be Jedha. Edwards describes Scarif as a "paradise," which was the reasoning behind shooting in Maldives. Scarif is the planet featured in Rogue One's new movie poster - a tropical paradise with an image of the Death Star looming over it. The second planet, Jedha is a Mecca-esque planet the is inhabited by those who have faith in the force, and are firm believers and supporters of the Jedi's cause, even though it is believed that the Jedis are extinct . It serves as home for both Chirrut Imwe and Baze Malbus, and currently faces the threat of the Imperial forces, Polygon reported.

Among the other details given, audiences seem to gravitate more towards what most speculate to be a huge spoiler for the movie. It was through a statement made by actor Jiang Wen, who plays Baze Malbus, where he alluded to Donnie Yen's character, Chirrut Imwe's alleged death in the film. This is based from a report by Vanity Fair. Further information regarding the massive spoiler can be found in the article done by Polygon. As a fair warning, SPOILER ALERT.
