Ed Solomon and Chris Matheson, the writing team behind Bill and Ted's Excellent Adventure and Bill and Ted's Bogus Journey, wrote the screenplay for this third adventure. Last April, Keanu Reeves revealed that the story would revolve around Bill and Ted writing a song that eventually saves the world.
It still isn't known what studio this seqeul will land at. MGM Studios currently owns the rights to the franchise, but it is said that this package is being shopped around to other studios for co-financing. It isn't known when production will begin, although it will have to wait until Dean Parisot wraps on Red 2, which he starts shooting next spring.
Keanu Reeves and Alex Winter will be back as the title characters. We also exclusively reported in April that William Sadler may return as The Grim Reaper.
