I picture the "woods" being very "Grimm Fairy Tale," so I almost think this should be done on a giant set with CGI help for backgrounds. Stylized, exaggerated trees, surreal lighting, etc. I don't see it being filmed on location anywhere. I think the reality of a genuine forrest would make the characters look like freaks.
It should be its own world where fantasy is the reality.
As far as adapting the material, the biggest challenge is having so many characters step forward and essentially deliver inner monologues where they tell us (the audience) about something that just happened (off stage) previously and what they learned from it:
Little Red - I know things now
Jack - Giants in the Sky
Cinderella - Steps of the Palace
Others as well.
These will have to be rethought for film. I think narrated flashbacks should be used sparingly, if at all. I would steer away from that approach. So they will have to come up with other ways to present those numbers, or even rewrite those moments to make them work on film. It won't be easy.
The best thing about this material for audiences is that it takes familiar stories and characters and tells us something new about them. We get Lapine and Sondheim's wonderful ideas about life, love, happiness, and loss, funneled through the Grimm world. And people already love it (it's Sondheim's most produced show).
The best thing about this material for the studios and the "money" involved is that fairy tales with "different spins" on the characters are very popular right now, on TV, Broadway, in books, and on the big screen. So this is a no-brainer to put it into production. The subject matter is "hot" at the moment.
I do think Disney is going to go full-out on it, the way they did with Oz the Great and Powerful. They spent upwards of $200 million on that movie.
I have a feeling Into the Woods will have an equally huge budget and will very likely be shot in 3D.
