How about someone like Rosie O'Donnell....
Now before you all beat the crapola out of me... She so desperately loves theater and really is not a singer (a bit off pitch) and she would be perfect casting if she could do it seriously. I mean think about it.. The part has an almost Norma Desmond quality about it it tearms of passion about something that she really has not talent to bring.
"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."
