Smokey and the Bandit II (1980) - 17 mistakes

Revealing: When the sheriff's car is flipped upside down, the sign behind the car is upside down too, so you can tell the car isn't really upside down.

Plot hole: Snowman manages to unload the elephant, summons twenty trucks to the middle of a desert and gets miles ahead of the Bandit for his approach, in what appears to be about ten minutes of time.

Deliberate "mistake": In a couple of scenes, Bandit's Trans Am's engine sounds are dubbed, and you can hear the shifting of a manual transmission when his car was an automatic.

Continuity: When Buford T. Justice's car goes off the drawbridge, it is a different older body style car than what he was driving originally.

Revealing: When Sheriff Justice's car falls off of the drawbridge, there are ropes visible on the sides.

Continuity: When Cletus is racing his truck in the beginning scenes, several times they show him out in the lead by himself, but then they'd cut to him inside the truck and he was always passing the same trucks over and over again.

Deliberate "mistake": Mountie Police cars are not red in colour. They are blue and white. Clearly filmmakers assumed cars matched colour of uniforms.

Plot hole: We are supposed to believe that The Bandit somehow built a net out of rope large enough to support a 9,000 lb elephant, was able to suspend this 9,000 lb elephant (inside an enclosed trailer, no less), all by himself in one night and on a drunken stupor. That's some talent.

Continuity: Bandit and Frog are driving in the T/A with the windows up and the T-tops on. When Bandit passes the screaming girls in the Eldorado, the windows are down and the T-tops are off. They then cut back to the inside of the car with the windows up and T-tops back on.

Factual error: The Bandit is in a showdown with Buford T. Justice in a desert mountain range shortly after crossing into Texas. There are no desert mountain ranges in eastern Texas.

Revealing: Right after one of the Mountie's cars is split in half by the snowplow, you can see the mini-wheel used to keep the half-car propped up.

Plot hole: How can a doctor (not a veterinarian) with no medical equipment tell for certain how far along a pregnant elephant is, especially when the gestation period for an elephant is 20-22 months?

Continuity: When the Bandit's car jumps over Buford T. Justice's car, Justice's car somehow turns into an older body style car than what he was originally driving.

Revealing: When Mean Joe Green tips over Sheriff Justice's car, parts of the engine are missing.

Factual error: There is absolutely no way a Trans Am can tow the weight of a 9,000 lb elephant, plus the weight of a newborn elephant and 2 trailers. Such weight with a car like that would, at the very least, break an axle and destroy a transmission.

Plot hole: Cletus goes to Bandit's motel room at night while he's drunk and calls Frog who is marrying Junior again in the daylight. She then comes to Bandit's motel room to meet him that same night (seemingly in a matter of minutes) and when she gets there, Bandit somehow is completely sober.

Continuity: When Smokey's about to try and jump the bridge, we see it rising, he starts pulling away, then we see it lowering to flat, then in the next shot it's raised again as he drives up it.
