Jim Steinman wrote a very...interesting score for one. Back in the early 2000s. Tim Burton was attached at one point. Obviously, it did not materialize.
He's certainly the most theatrical superhero, with the most theatrical world.
I actually have some of the songs from the Jim Steinman "Batman" -- I love his music so I enjoyed it.
"Whenever I get gloomy with the state of the world, I think about the arrivals gate at Heathrow Airport. General opinion's starting to make out that we live in a world of hatred and greed, but I don't see that. It seems to me that love is everywhere. Often it's not particularly dignified or newsworthy, but it's always there - fathers and sons, mothers and daughters, husbands and wives, boyfriends, girlfriends, old friends. When the planes hit the Twin Towers, as far as I know none of the phone calls from the people on board were messages of hate or revenge - they were all messages of love. If you look for it, I've got a sneaky feeling you'll find that love actually is all around."
I have that Batman/Steinman demo somewhere. I love Steinman--albeit often in a guilty pleasure sort of way, but some of it can't be enjoyed even in that way (like the Joker's song about toys if I remember right.) A couple of tracks were used on Meat Loaf's Bat Out of Hell III album...
(And I believe the Bat Out of Hell musical is still going forward isn't it? For Toronto? Of course that's not Batman, but a post apocalyptic, homoerotic Peter Pan take that Steinman has sorta been working off and on on since the late 60s it seems with The Dream Engine...)
^ Yes, in fact it's still going forward. They're having a developmental lab at Pearl Studios that's closed to the public. Michael Reed is musical supervisor, and the cast includes Julia Murney, Christina Sajous, and Justin Sargent (who recently appeared in the 54 Below Steinman tribute show Total Eclipse).
