The whole point of the alien “ghouls” at the center of They Live is that they can be anybody, from the lady next to you at the supermarket to the cop who’s arresting you to the President of the United States. In actual fact, though, the ghouls in the film aren’t just anybody. They’re mostly one guy: Jeff Imada, who was also the film’s stunt coordinator. According to Imada, Carpenter originally hired actors to play the ghouls in the film, but wasn’t too happy with the male actor in particular, and asked Imada to begin doubling. Within all species, there is a genetic component to longevity. Our genes control the aging process at the very minutest level within our cells, and some of us simply inherit better genes for longevity than others. The same applies to guinea pigs. There is widespread debate among taxonomists about the classification of wolf species. Some that have been regarded as separate species are now considered hybrids (the result of reproduction that mixes two different species) or subspecies of the gray wolf. A subspecies is a group of individuals of the same species that share a distribution, habitat, history, morphology or specific behaviors. There are less differences between subspecies than between species.

The world’s tiger population has declined to about 3,200 tigers since the beginning of the 21st century. A century earlier, the same population was estimated at 100,000. The Indian, or Bengal, tiger makes up about half the total tiger population.Look out for On land, look for five-toed footprints in waterside mud or sand, and spraint (droppings) full of fish bones and crab shells left in prominent places. Despite the fishy contents, otter spraint smells sweet, rather like hay. Morales, Alex (20 December 2006). "Komodo Dragons, World's Largest Lizards, Have Virgin Births". Bloomberg Television. Archived from the original on 8 October 2007 . Retrieved 28 March 2008. Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild, their range has contracted due to human activities, and is likely to contract further from the effects of climate change; due to this, they are listed as Endangered by the IUCN Red List. They are protected under Indonesian law, and Komodo National Park was founded in 1980 to aid protection efforts.

I can’t find an equivalent study in guinea pigs, but in 2013 Dr Dan O’Neill and colleagues at the Royal Veterinary College in the United Kingdom reported that mongrels live on average 1.2 years longer than purebred dogs. And it’s likely that hybrid guinea pigs also live longer on average than pedigree guinea pigs.

Carpenter was also responsible for one other key element of the film’s sound: The deep alien voice saying “sleep” is his, recorded and manipulated by Howarth.
