In the books, the professor was no sort of grumpy tyrant would wouldn't let children play--Mrs. McReady was not a Wicked Stepmother.
how long has it been since you read the books?
That was the first thing that I noticed when viewing the trailer (which is awesome...)
The whole depiction of the professor and Mrs McReady in that fashion was far from the book. And the wardrobe wasn't covered with a big sheet, either (iirc).
My 6 year old daughter and I are reading the series now, just started Prince Caspian last night. I'll have to see the movie first before I take her, I'm not sure how far they'll go in the violence area.
Just a preview. And I admit I'm highly mistrustful of Disney getting their beastly hands on the material. The preview was lovely. But beauty (and it was beautiful) won't take this movie to greatness.
