Bill & Ted star Alex Winter has shared that a fourth installment in the beloved science fiction comedy franchise is in early development.

The franchise began in with 1989's "Bill and Ted's Excellent Adventure" and most recently delivered 2020's third installment "Bill and Ted Face the Music".

Winter, who plays Bill S. Preston Esq. in the three films to date, appeared on The Sarah O’Connell Show recently where he indicated Solomon and Matheson are currently working on an idea they’ve all sparked to.

Winter says the movie will only happen if he, the writers and Keanu Reeves are all on board with the script:

"We're tinkering with a fourth movie idea that all of us like, and the guys are going to write, so we’ll see. It takes us time to get these things going, and we never want to do them unless they’re great.

They Solomon, Matheson, co-star Keanu Reeves feel the same way, it has to be right. We love the Bill & Ted movies because they’re oddball, and they’re not typical mainstream films. They’ve never been cash-grab movies; nobody has gotten rich off the Bill and Ted series. We really do make them sincerely from a place of love and interest.

There’s a really good idea that the writers came up with for a fourth that’s kind of obvious. I don’t want to give it away — I can’t give it away because I would be drawn and quartered — but it is a really good idea, an obvious idea. It will get written, and we’ll see if we can actually get it made."

Winter portrays William "Bill" S. Preston Esq. in Bill & Ted, opposite Keanu Reeves' Ted "Theodore" Logan. The film series follows the titular metalhead slackers as they travel through time while trying to fulfill their destiny to establish a utopian society in the universe with their music. The first film, Bill & Ted's Excellent Adventure, was released in 1989 to positive reviews. The film also grossed $40 million worldwide against a $10 million budget, meaning that it was enough of a success to greenlight a sequel: 1991's Bill & Ted's Bogus Journey. Bogus Journey earned mixed reviews from critics but was still a minor box office success, grossing $38 million, although it cost $20 million.
