YES to 'DEATH'! I love that movie.
I think as far as technically 'unoriginal' sources go, I always want people to take stories with a little bit of dust on them. Not that 'DEATH' is necessarily the best material (though I do think that with casting ^ them and a brilliant writer and a less money-hungry Julie Taymor, it could do WONDERS), but it's been only lightly remembered for twenty years and it's (IMO) hilarious and music could give the piece more of a soul (or a pulse (; ).
So, fellow writers, stop flinging franchises at us and take some moderately successful plays and movies that have aged in quiet dignity and make good ('Women/Verge" sounds promising). :)
