Gemma and Tom are a happily in love young couple who are looking to purchase a starter home. They visit a real-estate agency for a brand new housing development called Yonder. Met by a strange and persuasive real-estate agent, they’re convinced to follow the unusual agent to tour the neighborhood that has been marketed as the family forever home with everything they could ever need and want. A row upon row of identical houses and yards go as far as the eye can see and before the tour of the rather ordinary house number 9 ends, Gemma and Tom find themselves alone inside with the bizarre agent gone. Their efforts to leave the mysterious residential suburbia proves impossible as each turn leads them back to house number 9. When a box containing a baby boy is left at the doorstep with a note to raise the child to be released, the young couple reluctantly reside into domestic confinement.

Vivarium defined is an enclosure, container, or structure adapted prepared for keeping animals under seminatural conditions for observation or study or as pets, like an aquarium or a terrarium. “Vivarium,” the 2019 movie, embraces the definition, twisted into an idiosyncratic neighborhood block of duplicity from the “Without Name” director, Lorcan Finnegan. Story concept is flushed out by Finnegan and “Vivarium’” credited screenwriter, Garret Stanley, in their second collaboration for the director’s sophomore feature endeavor that’s a panicking puzzle in every square foot of Yonder’s backwards backyard. The film resonates with echoes of Finnegan and Stanley’s seminal short film, “Foxes,” from 2012, revolving around a couple living in a remote and forgotten housing development and become drowning in obsession, madness, and malaise as shrieking foxes surround their isolated home. There’s an equating animalistic instinct to each film that brandishes many of the same motifs as well as joining themes that are corralled in Finnegan’s copious foreboding and disconnecting dehumanization narrative. “Vivarium” is produced by XYZ Films (“Tusk”), Fantastic Films (“Stitches”), PingPong Film, and Frakas Productions (“Raw”).

The happy, young love birds are played by Imogen Poots (“Green Room” and “Black Christmas” 2019 released remake), who has an underlining affinity for not typecasting herself in the same role, and Jesse Eisenberg (“Cursed” and “Zombieland”), who manages to step a foot outside his conventional performance of a rattle mouth, know-it-all. However, Eisenberg deserves the praise of a man with severed ties from reality as the actor embraces a reserved manic by channeling Tom’s obsessive need to dig, an aspect of his handyman profession he’s good at in perhaps providing an escape from cage-less confinement, and being the bearer of skepticism of caring for an abnormal child. Gemma has complications of her own confronting her educator responsibilities for young children. She struggles with internal conflict, does she still use her innate care and instruct a young mind or in self-preservation, take Tom’s passive aggressive approach? Poots and Eisenberg share a mutual, caring bond that defines Gemma and Tom kind of steady, kind of loose relationship that gradually devolves civilly, like the amicable breakdown of a marriage revealing lost, but not forgotten love between two people. Along with the surreal atmosphere, “Vivarium” grades well in the creepy kid department with the child in Tom and Gemma care, but don’t even bother giving a name. Dubbed with a playful man’s voice, a shrill scream ignited by displeasure, a knack for imitating, and always dressed in Sunday’s best, Senan Jennings’ middle aged boy presence is a supernova of chilling proportions with a performance that gives his co-stars a run for their money while Eanna Hardwicke is equally spasmodic and creepy as the grown up, young man version of the boy with a little more alienating know-how and clandestine about his origins.

Finnegan and Stanley pursue thought-provoking substance of human corporeal limitations and how we, as humans, cycle through them with such cavalier ease. The opening scenes examples this with the practice of the common cuckoo laying their mimicry egg inside the nests of other birds. As a brood parasite amongst birds, the cuckoo egg hatches and the cuckoo chick pushes out the mother birds’ inborn chicks and becomes the sole chick in the nest with the surrogate mother tending to the cuckoo’s dietary needs. When the cuckoo is matured, it is grossly larger than the mother bird and, also, mimics the bird species to an extent, much in the same way of the boy or young man Gemma and Tom surrogate as being the unintended mimicry that infiltrates and ousts the limitations of his foster parents. Finnegan and Stanley also explore the parental lifecycle with the theme that our children will replace us, extend our legacy, but we will ultimately be forgotten. “Vivarium’s” craft dictates a larger scale, disproportionate, otherworld teemed with secret subterranean corridors leading to other disturbing observatory immures, making for a stimulating meta-induced terrarium as we watch miniature versions of Jesse Eisenberg and Imogen Poots suffer inside a screen from the comfort of our couch.

If you’re stuck at home, living the quarantine life you’ve always wanted, “Vivarium” may just break of your introverted stance on home with it’s “Black Mirror” and “Twilight Zone” encouragement. Because of the COVID-19 pandemic, the Vertigo Releasing and Wildcard Distribution released film has circulated digital only on the following platforms in the UK: iTunes/Apple TV, Amazon, Sky Store, Virgin, Google Play, Rakuten, BT, Playstation, Microsoft, Curzon Home Cinema, and BFI Player. Unfortunately, I will not be able to comment or critique of the audio, video, or bonus features of this release due to the varying elements of a digital screener. Novel, suspenseful, and a great film to brood over, yet difficult envisaging, “Vivarium” truly resembles slithers of somber dimensions of an upside world with lashings of surveillance paranoia.
