On the extras menu you can scroll up and down a list of extras. When you reach the bottom if you continue to go down, the cursor will disappear. Hit enter and you can watch a homemade video of the rehearsal for the dance finale. There is no commentary or captioning. The audio is just what the camcorder picked up. Not overwhelming in itself but interesting to watch.
Reviews: DVD Talk also has a review of
Dirty Dancing: The Ultimate Edition by Randy Miller III.
