Trivia: M3gan's scenes were done with an actual person wearing a mask (with some CGI being used to animate the eyes and face.) The girl's name is Amie Donald, and she is an accomplished gymnast and dancer, and in the scenes with the hallway dance and running on all fours were not special effects, Amie actually did those moves.
Trivia: When one of the Comanche warriors is fighting the predator, he gets thrown over a large log. He lets out a Wilhelm scream. (00:51:33)
Trivia: Michael Myers kills Deb by pinning her to the wall with his knife the same way he killed Bob in the original 1978 film.
Trivia: The army officers estimated that the Allosaurus had a territory measuring about the same area as that of wolves, or roughly the square miles of Rhode Island. Rhode Island is nicknamed "The Ocean State" [also, "Little Rhody"]. "The Island State" would not be an appropriate nickname because Rhode Island is not an island... but it does have four islands. As the smallest U.S. state, more than 220 Rhode Islands would fit into the second-largest state, Texas.
Trivia: The teenagers had six-packs of "O'Doul's" beer (but the crease in the package makes it look like "O'Toul's"), which is a non-alcoholic beer/beveridge. Although considered to be alcohol-free (and legal for minors to drink), O'Doul's contains a small amount (0.4%) of alcohol. (00:30:40)
Trivia: The first film in the franchise to feature a female "Pinhead," as portrayed by actress Jamie Clayton, a trans-woman. Despite some minor backlash online, original Pinhead actor Doug Bradley has spoken out in support of Clayton, noting that the franchise has always been transgressive and unique, and that he loved her performance on the show "Sense8." It should also be noted that the Cenobites in the original book were mostly androgenous, though "Pinhead" was said to have a feminine voice.
Trivia: * "Quasi-Spoiler" * The mental or nutritional disorder wherein a person [or some animals, including dogs] eats/craves substances or objects that are not usually deemed to be "food" (or edible) is called "Pica." The word "Pica" is derived from ancient Latin and the bird "Magpie." Magpies have a reputation for eating almost anything/everything they can find, or have "indiscriminate tastes" and habits. Brecken, in this future world scenario, probably would not be diagnosed as having Pica. (00:03:28)
