Interesting to note is that the book is via TCG rather than directly from Disney's publishing house and is illustrated as well as having photos (I haven't seen it myself but everyone is wowed with how lovely it looks):
The Theatre Communications Group (TCG) has published a movie tie-in edition of the book and lyrics for the musical,.
Sounds like it might be worth picking up if you ever want to discuss the movie down the road. I'm sure such an edition will be hard to find not too far in the future!
And we have a Blu-ray with special features (I hope there are LOTS!) coming on March 24th.
It's now available for pre-order. Here's a poor quality pic of the new cover (the one showing on Amazon is supposed to be replaced - just be sure if you pre-order and want the extras that you're ordering the correct version).
