Hot take (not that it matters at this point): I actually think AI would have been much better suited for a film adaption than a musical, though only the latter was actually done. I think the music video for Jesus Of Suburbia alone kinda confirms that in my view. That being said, I think the film would have had to have been made and released towards then end of the 2000s, early 2010s at the latest. As much as I believe American Idiot, the album, has aged pretty well, I don't think a film adaption would age at all well.
That being said, maybe once GD become a full-fledged legacy act, they could then produce a short film related to AI. They'd probably have the budget to do that and might even be able to pull it off fairly well.
However, right now, there's less than zero demand for an AI movie.
