in the unaired pilot of "the crash", there is no end scene with the giant dog in the garbage dump. once it had been confirmed that "land of the giants" had been picked up by the network, the pilot was reworked and production began on succeeding episodes. however, a break in production occurred after 12 episodes were in the can (enough for a short run as a mid-season replacement), until the show received the green light on the decision to launch it as a full season the following fall.
