First time I saw Tarzan, in the opening number when the cheetah is suppose to attack and kill Tarzan's parents, the tree house is suppose to rise up and then when he "kills them" they are pulled off the structure and back into the wings but a rig. When I saw it through, something happened and the tree house never rose up so when it was time for the cheetah to do the thing, he just kinda came down, looked at them and the parents slowly walked backwards off the stage awkwardly.
