Daisy Ridley took part in a special "Star Wars"-themed edition of The Whisper Challenge alongside Jimmy Fallon Tuesday on "The Tonight Show."

The "Star Wars: The Last Jedi" star and Fallon wore headphones that resembled Princess Leia's hair buns in the game and listened to music as they guess which "Star Wars" phrase the other was saying by reading lips.

Ridley was up first and eventually was able to guess correctly that Fallon was saying the iconic opening line from the films, "A long time ago in a galaxy far, far away..."

Fallon, meanwhile, had trouble guessing that Ridley was saying Billy Dee Williams' character's name Lando Calrissian and then later struggled with "Help me Obi Wan Kenobi, you're my only hope," first guessing that the actress was saying "pickle" and "elmo."

"I forgot it was 'Star Wars'-themed," Fallon joked.

Ridley will be seen in "Star Wars: The Last Jedi" when it releases in theaters on Dec. 15.
