Prior to purchasing the new blu ray version of "The Wizard of Oz", I sold my 3-dvd collection of the film to fellow employee at my office. I recall that on the dvd, there were scenes in which the wire supporting Bert Lahr's tail were quite visible in some of the Emerald City scenes. In fact, in one of the dvd's documentaries, the folks who were involved in the dvd transfer made a point of saying they debated whether to remove the wire or not, ultimately deciding to leave it in for the sake of "purity". I watched the blu ray version a couple weeks ago - just the movie - and I don't recall seeing that "tail wire" during the Emerald City scenes. (Maybe I was just tired and not being all that observant !) I might replay those scenes over the weekend to see if the wire really has disappeared. If so, then it would appear that the folks in Burbank may have had a change of heart about this item. Does anyone have any information about the debate over the "tail wire"?
