and Ted "Theodore" Logan, portrayed by Alex Winter and Keanu Reeves, respectively, two metalhead slacker friends who travel through time and beyond while trying to fulfill their destiny to establish a utopian society in the universe with their music.

The leaders of this society send Rufus (George Carlin) to help Bill & Ted pass school and assure the future with the aid of a time machine, which appears as a phone booth.

This gives them the opportunity to find allies to stop their robot doubles and De Nomolos before an upcoming Battle of the Bands where they must also rescue the princesses to whom they are engaged and start their musical careers.

Kelly warns their teenage daughters, Billie and Thea, about their plight, and the two go off into the past to help create a band to make the great song for their fathers in time.

Shortly before the release of Face the Music, Winter and Reeves discussed the possibility of a fourth Bill & Ted movie, the latter telling Rachel Smith of Entertainment Tonight that it would be "up to the fans".

[3][4] When asked in an interview with DiscussingFilm in August 2020 if the characters of Billie and Thea could result in a sequel or spin-off film, writer Ed Solomon stated, "It wasn't when we were first writing it, but as we saw Brigette and Samara inhabit these roles, I thought for sure if there was interest and people wanted to carry this forward, the Bill & Ted spirit, I would absolutely let those characters carry it forward.

The first season was produced by Hanna-Barbera and ran for 13 episodes on CBS in 1990, featured the voices of Carlin, Winter and Reeves returning to their roles in the film.

A later live-action series, featuring none of the cast from the films, included Christopher Kennedy as Bill and Evan Richards as Ted (who also voiced the same roles in the animated season produced by DIC).

Its popularity led to the ongoing Marvel series Bill & Ted's Excellent Comic Book by Evan Dorkin, which lasted for 12 issues.

A PC title and nearly identical Amiga and Commodore 64 port were made in 1991 by Off the Wall Productions and IntraCorp, Inc. under contract by Capstone Software and followed the original film very closely.

An action-adventure video game based on Bill & Ted's Excellent Adventure that was released in North America by LJN for the Nintendo Entertainment System.

Typically the show parodied the past year's worth of notable pop culture events, featuring locally cast performers as the title characters.
