This idea came to me out of the blue today and now I wish very much to make it a reality! Or at least to write the script and the songs and perform demos of the latter. I have little hope of ever being able to actually put together a production, as I have no connections or resources or charisma and almost no friends. But if someone writes a BIONICLE musical adaptation, perhaps someone else who likes it will find a way of performing it—that's what happened with the Death Note musical.
Anyway, I decided to run this idea by the residents of BZPower as a first step. If there were a BIONICLE musical, what would you want it to be like? Obviously, it would be impossible to cram the entire storyline into a single play, unless actors and audience were willing to remain in the theater for days on end. Personally, my first thought is a Compressed Adaptation of the first three years of the theme, starting with the Toa's arrival on the island and culminating in the transformation of Takua into Takanuva, his defeat of Makuta, and the awakening of Mata Nui (which, in this version, really would happen immediately after Makuta's defeat—whether or not Mata Nui is a giant robot in this version, I am not yet certain). I think it would be possible to fit that into 3 hours, with two intermissions. (It might be easier to just adapt MoL, but then we wouldn't get the Toa's early adventures and character development, which would be a shame, I think. Don't you want to see Kopaka's and Pohatu's first meeting played out on stage? I sure do!)
What narrative moments would you most want to see as songs? What parts of the narrative would you cut or expand upon? Or would you prefer an entirely different way of adapting BIONICLE into a musical than the one I've outlined above? What would you do about costuming (I don't think full body, set-realistic Toa suits would be a good idea, as they would greatly impede acting—something more symbolic, a little like the costumes in the Lion King musical, would surely work better and be easier to create besides)?
