Corrected entry: In the 2nd Tremors film, there's a scene towards the end when Burt uses his LAR Grizzly Big Bore .50 BMG rifle on a shrieker, and the .50 cal round reduces it to spaghetti sauce. However, in this movie, Burt uses a .50 cal round to handle the Shriekers in Argentina (in the very beginning), and this time the bullets only cause bullet holes, and not massive carnage.
Corrected entry: After the foursome spend the night on the rocks, their shirts are buttoned up tight, but while Burt retreaves his walkie-talkie and guns out of his truck, both Miguel and Jody's shirts are unbuttoned.
Corrected entry: During the scene where Jack is talking to Jodi about the 'complimentary ice', Jodi has an Apple MacIntosh laptop on the desk. The logo on the back of the laptop does not have the 'leaf' on the top of the apple. this was done to avoid copyright issues.
Corrected entry: When Burt is looking at the comic books, the name Shreikers is misspelled. It should be spelled Shriekers.
Corrected entry: In the scene where Jack and Burt first meet, a boy tourist stands in front of the "Welcome to Perfection" (with the graboid rising out of the ground) sign and yells to his mom, "Take a picture of me with the tremor." Jack yells back, "They're called graboids." This was very probably done because when the first Tremors movie came out, there was confusion about what the monsters were supposed to be called.
Corrected entry: When the graboid bites the tire on the old pickup and causes it to go flat, you can see the bright flash from the explosive charge.
Corrected entry: The scene where the girl and her mother are in the store, the girl puts a huge piece of meat in the microwave - that is the strongest microwave I've ever seen, it took a mere 3 seconds to heat that up...
Corrected entry: When Burt is eaten by the Graboid, he is in a barrel. When Jack cuts the Graboid open to get Burt out, where is the barrel?
