It's official: Bill and Ted are getting a third movie. The sequel to 1989's Bill and Ted's Excellent Adventure and 1991's Bill and Ted's Bogus Journey, which has long been in the works, was announced Tuesday at the Cannes Film Festival, the AP reports. The stars of the original cult classics, Keanu Reeves and Alex Winter, will reprise their roles; the movie will involve middle-aged Bill and Ted attempting to write the song that will save the universe and, of course, time-traveling in their quest to do so, Rolling Stone reports. Bill and Ted Face the Music was written by franchise creators Chris Matheson and Ed Solomon; it's in pre-production with no release date yet set. (Years ago, Reeves said the sequel involves Bill and Ted "drift[ing] off into esoterica and los[ing] their rock.")
