Attack the Block exists in the same universe as Doctor Who.
No real reason other than the monsters seem like perfect badguys for the Doctor.- The idea of any of the gang as companions is oddly appealing.
- This can be the only reasonable explanation as to why no one made a Doctor Who reference during the course of the film.
- And, given the reveal of the 13th Doctor being played by Sam's actress...
The aliens are able to "turn off" (or hide) their bioluminescent teeth, they just have no reason to do so over the course of the movie.
Having glowing teeth is cool and creepy, but makes it a little hard to be stealthy. If they were going after the main characters as prey note , they would be hiding their teeth and thus be able to stand out much less in the dark; Since they're only going after humans so they can find the female of their species, they must want to be seen for the sake of intimidation.- Either that or the glowing teeth are unintended by their species. They don´t seem to have eyes and seem to hunt/react almost entirely by scent and touch, so it´s possible they are not aware their teeth give their positions away.
- Another possibility is that the teeth are for show since they seem to be in some kind of "rut".
- Or they might act as a lure, like on a deep-sea angler fish. If their natural environment is in near total darkness (plausible, given that they appear to be blind and navigate by a combination of smell and echo-location), then their "absorbs all light/Vantablack" fur would mean the only thing visible would be their teeth - which don't look like teeth when their mouth is closed. Curious prey would be attracted by the small, bobbing lights, and not realise what they were until they were too close to escape.
- I sort of assumed these aliens weren't entirely biological- they were also sorta cyborgs. Just with blood and organs. When I saw their biolumenescent teeth turn off, I was reminded more of how robotic lights would turn off- it looked more like an LED turning off than how I imagined that bioluminescence would.
The aliens are Vulpimancers from Ben 10.
The first alien was the male of the species.
And the rest are female. Characters in the movie suggest the opposite, but one male and many females makes more sense than one female and many males, unless it's a Mister Seahorse situation. And there's plenty of species where the females are bigger/scarier than the males.The aliens are an artificial species...
...used as a terraforming weapon. After being deployed in slow-moving drop pods into a world's atmosphere by their creators, the creatures breed and feed at such a rapid pace that the host planet's ecosystems are overrun and the local lifeforms are wiped out. With any potential resistance eliminated in the initial waves, the creatures' creator species arrive and round up the strongest and most well-adapted specimens for reuse in a later invasion before wiping out the rest. With the planet cleared completely, the creators can begin colonizing. The aliens are a contingent of slats from the Jackelian Series, misdirected.
In The Rise of the Iron Moon, creatures very similar to the Attack The Block aliens are employed as foot soldiers by the invaders from Kaliban. Later events in the novel reveal that the invasion is one that crosses time as well as space. Throughout the Jackelian series, small hints are dropped that Jackels' world is actually our own Earth, albeit an Earth of the very, very distant future, in which the very laws of physics have changed. Because of a glitch in their cross-time transit, one of the invaders' transport canisters full of slats got diverted into the past, to expel them over London. The first alien wasn't a different sex, just a regular slat with its fur burned off due to early atmospheric entry. The living slats' teeth glowed because the aforementioned changes in the laws of physics interacted with the residue of blue blood on their fangs, from the Kal they devoured as a pre-takeoff meal. They pursued the boys, not because of pheromones, but because with no superiors to give them orders, they embraced their hunting urges and built-in malice towards whichever quarry catches their interest. The aliens can't smell.
I think that they don't have a nose. There are many lights in each of the aliens' mouths. Now are they teeth, or tonsils? The white creature was a juvenile; the black creatures are adults.
Note its small size and sparse fur - these could be examples of sexual dimorphism, but we can’t say for sure. The white creature arrived first as a coincidence or accident, rather than as an envoy. The pheromone markers are meant to call the adults to protect it and/or mark out a threat to the group’s young. The white creature is a male, and the black creatures are female.
It seems odd that the white creature doesn't have any glowing teeth while the black ones do. It may be possible that the white creature was actually a male while the black ones are females, and the glowing teeth are used to draw the white creature's attention for breeding purposes.
