Really wish i had seen this in 3D, it really is made for it! I liked the nods to the original and seeing the back story but no mention of the ruby slippers which were the wicked witchs sisters, thought she would have them tbh.
There are many connections to the original Oz film that couldn't be included due to Warner Brothers owning the rights to certain specifics of said film.
The production team were often pressed the concern of abiding by the stipulations set forth by Warner Bros. (via its Turner Entertainment division), the legal owner of the rights to iconic elements of the 1939 MGM film, including the ruby slippers worn by Judy Garland. Therefore, Disney was unable to use them nor any character likenesses from that particular film. This extended to the green of the Wicked Witch's skin, for which Disney used what its legal department considered a sufficiently different shade called theostein. The studio could not, however, use the signature chin mole of Margaret Hamilton's portrayal of the Wicked Witch of the West nor could they employ the Yellow brick road's swirl design for Munchkinland.
