The Wyld Stallyns are officially back, and Alex Winter is marking the start of filming on Bill & Ted's Excellent Adventure combined time-traveling shenanigans with the teenage culture of the day to great effect, as the tale of of two far-out high school dudes whose rock band would lead the world to salvation became an instant adventure comedy classic. A sequel, Bill & Ted's Bogus Journey, soon followed, as did an animated series and an assorted of other wider media and merchandise.

However, a Bill & Ted 3 was not forthcoming. Despite numerous calls from fans for Keanu Reeves and Alex Winter to round Bill & Ted's story into a trilogy, it wasn't until 2010 that firm news of a threequel began to emerge. Unfortunately, there was still almost a decade of work to go, and the creative duo of Chris Matheson and Ed Solomon have been continuously writing and re-writing the script for a third Bill & Ted movie in an attempt to do the film justice. Finally, in May 2018, began production last month, much to the relief of fans.

To mark the start of filming on Bill & Ted Face The Music, Alex Winter has posted a photo to his Twitter , showing the actor wearing a blue Wyld Stallyns T-shirt, along with the caption, "Day one. See you on the other side and to be excellent."

Perhaps the biggest takeaway for Bill & Ted fans isn't just the Wyld Stallyns shirt on display, but the fact that a third film is finally underway after such an extensive period of pre-production. For almost three decades, Bill & Ted 3 seemed stuck in development hell, despite the plethora of other, sometimes lesser-known, 1980s and 1990s franchises getting the reboot or sequel treatment.

Judging by the response online, there's a killing to be made if these shirts end of up as part of the official Bill & Ted Face The Music line of merchandise and, considering fans can buy a working children of their own, they are tasked with composing a new song to save the universe, leading to a "get the band back together" style story that isn't a million miles away from the film's real-life production.
