It shouldn't be much longer now until the Seven Dwarfs Mine Train in The Magic Kingdom at Walt Disney Wold opens and completes the New Fantasyland expansion. They haven't officially announced a date, but some time in May is what everyone seems to be expecting.
We've see plenty of shots of the outside and some concept art of the inside, but this video released by Disney shows us a bit more about the dark ride portion of this rollercoaster.
Disney has experimented with this sort of animatronics before, but there aren't many examples of it in The Magic Kingdom. As well as the traditional animatronic elements, they're able to animate the characters expressions much more than was previously possible. The results are impressive.
