While discussing his role in Grand Piano with Yahoo, Alex Winter -- aka as Bill S. Preston, Esq. -- dropped a few new details about the highly anticipated Bill & Ted 3.

He's set to return to the comedy franchise alongside co-star Keanu "Ted Logan" Reeves. "[Bill and Ted] will be 40-something, and it's all about Bill and Ted grown up, or not grown up," Winter said.

With so many classic franchises being modernized, Winter clarified that this new installment isn't a reboot. "It fits very neatly in the [series]. It's not going to feel like a reboot. The conceit is really funny: What if you're middle-aged, haven't really grown up and you're supposed to have saved the world and maybe, just maybe, you kinda haven't?"

That premise came about in part due to the real world time that has passed since the duo's last excellent adventure, 1991's Bill & Ted's Bogus Journey.

"Me and Keanu and [original writers] Chris [Matheson] and Ed [Solomon] are all very close and have remained close over the years," explained Winter. "We'd be having dinner and we’d be like, 'is there a point? Is there a way in?' We'd kick an idea around and go 'no,' and we would leave it alone for a bunch of years. I guess about four years ago we had an idea together that we thought was pretty great. I think it was because so much time had gone by that it was great."

Since that spark of inspiration, Winter confirmed that Matheson and Solomon knocked out a script that's been undergoing revisions over the past few years. A director -- Galaxy Quest's Dean Parisot -- signed on in the meantime. Despite numerous revisions, Winter said that the script is still on the road to completion.

Potential Keanu Reeves sequels have been making headlines lately, as the actor recently admitted that he might be interested in making Speed 3.
