The 1991 book version of the movie published by Berkley, written by Robert Tine.
This book doesn't include any photographs from the film
to illustrate the story, but it is notable for the fact that it
follows the original script for the movie and includes many of the omitted
plotlines and footage, including the more radical behavior of evil robot Bill
& Ted while trashing the dudes' apartment and the alternative ending in
which they must face their fears.
