VIDEO : Mark Hamill Tells Fans Who Is Laughing In 'The Rise Of Skywalker' Trailer

Audiences got their first peek at **Star Wars: The Rise of Skywalker** on Friday with a brand new teaser trailer.
Comicbook.com reports fans have been debating who is heard sinisterly laughing at the end of the trailer and if it is Emperor Palpatine.
Franchise star Mark Hamill told fans Saturday that the laugh is due to a crossover between the DC Comics and Star Wars universes.
The actor shared an image of the Joker from **Batman: The Animated Series**, a character he voiced.
Actor Ian McDiarmid confirmed this weekend that the Emperor would play a role in the new film.
