Peripheral (2025) – Cast & Characters

Premiering August 7, 2025, on BET+, Peripheral delivers a mind-bending psychological nightmare that redefines Black horror. Fresh off its Best Picture win at the American Black Film Festival and Best Director honors at the Michaeux Film Festival, the film follows Sasha Warwick (Andria B. Langston), a pregnant woman whose idyllic desert life shatters when her biochemist husband vanishes from a shadowy research facility. As Sasha uncovers a town hijacked by an extraterrestrial entity warping reality itself, she battles paranoia, mutated townsfolk, and her own unraveling mind to save her unborn child. Directed with visceral tension by Omar S. Kamara, Peripheral merges body horror, cosmic dread, and social commentary—exposing how systemic exploitation mirrors alien invasion.

The ensemble cast masterfully embodies creeping dread and shattered humanity, turning a sun-scorched desert into a labyrinth of terror. From bio-horror scientists to gaslighting agents, each performance amplifies the film’s exploration of autonomy, motherhood, and survival. Meet the faces trapped in BET+’s most audacious horror original yet.

Peripheral cast names

1. Andria B. Langston as Sasha Warwick

Andria B. Langston (Them, David Makes Man) delivers a tour-de-force as Sasha Warwick, blending maternal ferocity with bone-deep vulnerability. Langston’s performance—anchored in physical transformation (gaunt exhaustion, protective posture) and psychological unraveling—captures Sasha’s journey from devoted wife to desperate survivor. Her background in stage drama (August Wilson Theatre) informs the character’s soliloquies of dread, particularly when confronting hallucinations of her mutated husband. Langston trained with pregnancy consultants and studied real accounts of coercive control to ground Sasha’s terror in authenticity.

Langston’s Sasha is a landmark in horror: a Black final girl whose battle against extraterrestrial manipulation parallels real-world gaslighting. Her climactic showdown in the research facility—wielding a scalpel against biomechanical horrors—redefines resilience. “Sasha isn’t fighting aliens; she’s fighting erasure,” Langston states. The role, demanding stunt work amid 120°F desert shoots, cements her as a genre powerhouse.

2. Patrick Walker as Ramon Warwick

Patrick Walker (Snowfall, All American) haunts as Ramon Warwick, Sasha’s husband whose idealism lures him into the facility’s nightmare. Walker’s Ramon shifts from loving partner to a grotesque, entity-possessed puppet—his body morphing via prosthetics and CGI. Walker’s theater roots (*Broadway’s The Lion King) lend pathos to Ramon’s corrupted pleas for Sasha to “join him,” blurring menace with tragic devotion.

Walker collaborated with bioethicists to explore Ramon’s Faustian bargain: trading humanity for scientific transcendence. Flashbacks reveal his complicity in the entity’s spread, adding moral complexity. “Ramon’s tragedy is that he thought he could control the monster,” Walker reveals. His physical transformation, featuring tendril-like veins and irises that fractalize, is a practical effects marvel.

3. Dame Pierre as Detective Aaron Bell

Dame Pierre (The Equalizer, Power Book II: Ghost) grounds the chaos as Detective Bell, an outsider investigating Ramon’s disappearance. Pierre’s Bell embodies weary integrity—his skepticism of the town’s “perfect” façade clashes with local corruption. His arc mirrors real-world failures to protect marginalized communities, climaxing when he uncovers police collusion with the entity. Pierre’s chemistry with Langston fuels the film’s emotional core, especially when Bell risks his life to extract Sasha.

Pierre’s performance balances grit and empathy, informed by his Haitian heritage and advocacy for police reform. A chase scene through shape-shifting sand dunes showcases his athletic intensity. “Bell represents the system that arrives too late—but refuses to leave,” Pierre notes.

4. Patricia Mizen as Robin Ford

Patricia Mizen (Servant, Dispatches from Elsewhere) terrifies as Robin Ford, Sasha’s neighbor-turned-harbinger of the entity. Mizen’s Robin oscillates between Stepford Wife serenity and insectoid menace—her unnerving smiles and jerky movements signaling possession. Inspired by Invasion of the Body Snatchers, Mizen’s performance weaponizes suburban normalcy: a lemonade stand becomes a recruitment center for the entity’s hive mind.

Mizen mastered contortionist techniques for Robin’s physical unraveling. Her monologue about “the bliss of surrender” in a zombified PTA meeting chills to the core. “Robin isn’t evil; she’s empty,” Mizen explains. Her dynamic with Christian Seavey’s mutated husb,and Craig exposes the horror of lost autonomy.

5. Liam James Collins as Dr. Leo Bronner

Liam James Collins (The Witcher, Industry) embodies amoral ambition as Dr. Bronner, the facility’s lead scientist. Collins’ Bronner rationalizes atrocity as evolution, seducing Ramon with promises of “transcendence.” His clinical detachment shatters when the entity infects him, resulting in a Cronenberg-esque mutation scene where his skin crystallizes into alien silica.

Collins studied eugenics history to craft Bronner’s god complex. His final confrontation with Sasha—a bio-mechanical monstrosity pleading for death—becomes grotesquely tragic. “Bronner’s the Icarus of inhuman experimentation,” Collins states.

6. Dallas Hart as Agent Lance & Jordan Tortorello as Agent Keith

Dallas Hart (Cruel Summer, The Republic of Sarah) and Jordan Tortorello (The Terminal List) star as government agents weaponizing the entity. Hart’s Lance deploys gaslighting tactics to silence Sasha, while Tortorello’s Keith embodies militarized indifference. Their crisp suits and mirrored sunglasses evoke Men in Black, but their mandate is containment, not protection. A scene where Lance dismisses Sasha’s evidence as “prenatal hysteria” epitomizes institutional betrayal.

Hart’s icy charm masks Lance’s fanaticism—he believes the entity can “purify” society. Tortorello’s Keith, though stoic, reveals flickers of guilt when ordered to terminate Sasha. Their partnership fractures in the climax, exposing the cost of blind allegiance.
