According to one Burton site this is an Oompa Loompa this time around...
According to what I had read, this one is more true to the book than the first film. What's real sad is the screenplay for the first was even written by Dahl and the studio went in, made changes and added most of the songs without consulting him. There were a lot of strings to pull with estate even to get this remade to keep it true to the original material.
I'll find the Burton sketches when I get to my home computer tonight to post them tomorrow.
