Ferngully The Last Rainforest (1992)
NO. Why?
The Swan Princess (1994)
Didn't people dislike the singing contest number in The Little Mermaid? Also you would need more/better songs. The sets feel like they would pose a problem unless they were a bit boring in which case... what's the point of putting it on stage? But it doesn't seem like the kind of property that would have a big budget. How do you represent her as a swan? I feel like it could be an OK piece for children's theater with puppetry or something like that but there's a reason why it works better as a movie.
Cats Don't Dance (1997)
So many animals... Animals on stage can work... but it's tough. Also, it's more of a send up/homage to classic movies. Again, unnecessary.
Pebble and the Penguin (1995)
Oh, boy. Not getting into it. But you've got a real Don Bluth thing going.
Thumbelina (1994)
I guess you could cast an Alli Mauzey/Kristin Chenoweth sized actress but... again, it feels unnecessary. Also, again so many animals. As far as the story and score go, I do think there's a stronger case for a stage adaptation. And we'd finally get a Barry Manilow musical on Broadway.
