Continuity mistake: When John Travolta is showing the young boy how to tighten the air filter top, he makes sure the boy gives the wing nut an extra twist. Next he notices a car coming up the road and he leaves. When the FBI agent comes over and looks inside the hood of the truck, the air filter top is again off, the air filter is out and the carburetor is exposed.
Other mistake: After John T's passing, the screen caption reads "1 year later" and they are celebrating his birthday. The light flash happened on his birthday and took three months to be diagnosed and die. The caption should actually say 9 months later.
Continuity mistake: When Robert Duvall crosses the street to enter the hospital, torrential rain is drenching everything. After Duvall enters the hospital, the interior shot shows him and his raincoat completely dry.
Continuity mistake: In the scene where Doc gets angry with the locals in the bar, he slides his glass along the bar and smashes all the other glasses on the bar.

Answer: 1. After losing consciousness a second time, George wakes up in the hospital and is told by Dr. Brunder that instead of the tumor destroying brain function, it has been stimulating it not only making George hallucinate seeing a bright light, but, was also responsible for giving him his abilities. Unfortunately, by the time the tumor was detected, it had grown out of control meaning that George had only a short time to live making a search for a cure impossible, especially since he was told there was a very slim chance of survival if he had it removed. 2. If George had tried to use telekinesis to remove the tumor, he would probably have ended up killing himself in the process.
