<P> The film also employs computer - generated imagery for the scenes where Bill & Ted are travelling through the' Circuits of Time', created by the VFX house Perpetual Motion Pictures . </P> <P> The film's writers, Ed Solomon and Chris Matheson, appear in the film's ice cream scene . Solomon is credited as the "stupid" waiter, and Matheson is credited as the "ugly" waiter . They are given similar credits in Bill & Ted's Bogus Journey . </P> <P> When Rufus plays his guitar solo, the hands in the close - up are those of Stevie Salas, who composed the film's guitar music . </P> <P> The film took nearly two years to make . Filming took place from February to May 1987 and it was planned to be released in 1988 . However, the film's original distributor, De Laurentiis Entertainment Group, went bankrupt . Orion Pictures and Nelson Entertainment bought the rights to the movie in 1988, and it was released theatrically on February 17, 1989 . As a partial result of the delay, certain dates in the film originally scripted as "1987" had to be re-dubbed as "1988". The copyright date of this film is 1989, while 1988 incorrectly appears on the DVD cover (though some copies still note 1989 as its release date) and 1987 appears on the back of the Blu - ray release . </P>
