In Star Wars: The Last Jedi, the Skywalker saga continues as the heroes of The Force Awakens join the galactic legends in an epic adventure that unlocks age-old mysteries of the Force and shocking revelations of the past. After creating the scores for the seven previous Star Wars films, five-time Academy Award-winner John Williams returned to compose and conduct his signature sweeping music for The Last Jedi. As with Star Wars: The Force Awakens, audiences can expect to hear quotations from earlier Star Wars themes. For Williams, incorporating the previous themes is part of the fun of scoring the Star Wars movies and helps create what he calls "the fabric of the films." Many of the characters also have their own musical themes. Williams explains, "Rey has a theme, Kylo Ren has a theme, Finn has one, Rose has one...These thematic elements infuse the whole score and are part of what moves the film along, giving its sonic outline. In the Star Wars films, the orchestra can be as extrovert as it wants to be at given times, so it really becomes a big part of the fun and imagination of it all."
