I doubt that the theatre landlords are going to offer DreamWorks their off-the-beaten path theatres like the Nederlander or the Hirschfeld, both of which as have been stated, are too small for Shrek.
If you've seen a Tim Hatley design (like Spamalot or Private Lives), his shows always seem to have a LOT of set. Think big.
Begin at the beginning and go on till you come to the end: then stop.
