AMC's website currently lists The Rise of Skywalker's runtime as 155 minutes. If accurate, this would make Episode IX the longest film in the franchise, beating out The Last Jedi's previous record of 152 minutes.
In August, percussionist Don Williams, the brother of longtime Star Wars composer John Williams, hinted that the film may have clocked in at 135 minutes -- a number that would have put it more in line with The Phantom Menace. However, this could have been misinterpreted as he was alluding to the number of minutes of music his brother had to write, which doesn't necessarily translate to the overall length of the film.
Directed and co-written by J.J. Abrams, Star Wars: The Rise of Skywalker stars Daisy Ridley, Adam Driver, John Boyega, Oscar Isaac, Lupita Nyong'o, Domhnall Gleeson, Kelly Marie Tran, Joonas Suotamo, Billie Lourd, Keri Russell, Matt Smith, Anthony Daniels, Mark Hamill, Billy Dee Williams and Carrie Fisher, with Naomi Ackie and Richard E. Grant. The film arrives on Dec. 20. Advance tickets are available now.
