I had an idea along those lines. There is a large screen in the background of the stage that they sometimes use for lighting and casting shadows. I thought of a scene where young bruce is there with his parents dead and this big shadow behind him stands up and its batman, and then he opens his cape.
I would probably have a bad guy, probably the joker and harley quinn. And I would probably grab dialogue from different stories. The whole scene with bruce sitting in the armchair in year one, the 'I made a promise speech', stuff like that.
I mean the animated series had great stories and they only had around 22 minutes. I have 30, so I mean I should be able to make something... I'm just trying to think of a plot. I was thinking maybe instead of the stuff above of doing an adaption of mad love. Either that or the origin of batman. There are a lot of creative ways to convey ideas in theatre, so any ideas anyone has would be cool.
