Jurassic Park has some inconsistencies that theorists just love

A few Jurassic Inconsistencies:

(at around 1h 3 mins) When they arrive at the T. rex cage right before the black out, we can clearly see the ground inside the cage is approximately flush with that outside the cage. But when the T. rex escapes and begins to terrorize the two trucks, the ground in the cage is shown to be at least 100 feet below where it was before.

Hammond has a pronounced Scottish accent at the start of the film, which deteriorates markedly in just a couple of scenes. By the end of the film he has an upper class English accent.

(at around 1h 25 mins) When Ellie enters the cafeteria where Hammond is eating ice cream the ceiling fans are working despite the power being out.

(at around 1h 3 mins) Gennaro runs off and leaves Lex and Tim in the Explorer when the T. rex appears, and leaves the car door open. Later, we see the same vehicle through the windscreen of Grant and Malcolm's vehicle and the same door is closed. Later on still, Tim shuts the door which is what attracts the T. rex' attention.

(at around 1h 4 mins) The goat's leg mysteriously disappears just before the T. rex smashes into the roof of the car.
