 CONT: Luke attempts to crash the gate while driving Nells Gremlin.  After he hits the gate, a large oval portion of the gate that has  spikes falls down onto the top of the car. The oval portion covers  the hood, and the spikes penetrate the roof of the car. The doors  cannot be opened because of said spikes. In the last scene where the  caretakers (Mr. and Mrs. Dudley) come back to unlock the gate, the  Gremlin is still there, but the oval portion that fell is still in  the gate, and there are no holes in the roof of the Gremlin.
