You'll fit in real well here...
If I were Disney I would release this December 5th (Happy 112th Walt!). The first thing I thought of however is Hanks' voice. I've heard Walt's before (Who on this board has not) and I think it would be weird hearing Walt speak like Woody.
If you watch the trailer, it's really not that weird. Mr. Hanks really seems to capture Walt's enthusiasm and his cadence and really does a remarkable job, even just in the short clips you hear in the trailer. Overall, if the movie is half as good as the trailer (which I have watched over a dozen times now) then it will be awesome and Tom Hanks and Emma Thompson will deserve their Academy Awards (because if this movie isn't Oscar bait, nothing is.)
