Revealing mistake: During the party, one of the security guys shoots the alligator, who then whips him with the tail. The guy flies in the air, and to the left of the screen when he falls there's a string plainly visible to help moving the tail. (01:15:45)
Revealing mistake: A policeman hilariously crashes his car because he was coming in too fast when the kids escaped the molegator. The car that explodes has square, all red emergency lights, but the car that was speeding through the street had red and blue lights of a different shape. (00:44:50)
Revealing mistake: Obvious B-movie special effect when the alligator breaks through the sidewalk, supposedly creating earthquake-like tremors that are simply someone shaking the camera up and down and the cement bends and deforms like cardboard. (00:44:00)
Revealing mistake: Gutchel brings in the sewers the animal carcasses using the supermarket cart. He gets inside, then passes a first tunnel, then another one...or rather, passes the exact same tunnel as before, but in the other direction, to make it look like he travelled a bigger length - just check the graffiti on the wall, it's the same one. (00:09:25)
Revealing mistake: After the press conference, there's a close-up of a newspaper ("The National Probe") which features obvious repetition of the same paragraphs over and over. (00:16:55)
Revealing mistake: After the unmissable scene of a very excited Henry Silva appraising alligator dung, there's a small intermission showing some news on the TV. The "tv" is a literal cutout of a television that frames the footage. It's not even cut properly, the lines are jagged and not smooth. (00:52:50)
