 CONT: When Axel is rescuing the two kids from the damaged "Spider"  ride at Wonderworld, the rope which he rescues them on grows several  times between shots. In the first few shots, the rope clearly ends  only a few feet down from where Axel and the children are hanging;  there are obviously hundreds of feet between the end of the rope and  the ground. In the next shot or two, the three of them are sliding  down on a section of rope which was not previously there. And in the  last few shots, Axel and the kids finish sliding down the rope  (which now appears to end about one foot from the ground), and run  to avoid being crushed under the falling carriage.
