Cast and Characters

Dave Bautista headshot
Dave Bautista
as Leonard
Bautista delivers the film's signature performance: a towering former WWE star asked to play the gentlest character in any Shyamalan film, a Chicago second-grade gym teacher whose entire physicality has been rewired to soothe a frightened child. The casting trick is the film's thesis — the most physically threatening person on screen turns out to be the most morally serious — and Bautista carries it with a vocal placement that drops almost into a whisper for the cabin's hardest scenes.
Jonathan Groff headshot
Jonathan Groff
as Eric
Groff's Eric is the partner more available, theologically, to the strangers' framing — a parent who once trained as a Catholic-school child and has not fully reconciled the apocalyptic vocabulary with the adult he became. The performance carries the film's hardest interior arc: a man with a head wound being asked, in real time, whether what he is seeing in the cabin's light is a hallucination, a vision, or a final argument he is no longer in a position to refuse.
Ben Aldridge headshot
Ben Aldridge
as Andrew
Aldridge's Andrew is the film's central skeptical voice and the script's load-bearing argument against taking the strangers at face value. The Boston civil-rights-lawyer backstory is doing real work in his readings of the room: every minute the four spend explaining themselves, Andrew is mentally cross-referencing them against every hate-crime case file he has ever worked. The performance keeps the courtroom posture intact while the body is tied to a kitchen chair.
Nikki Amuka-Bird headshot
Nikki Amuka-Bird
as Sabrina
Amuka-Bird's Sabrina is a Southern California nurse whose professional reflexes — the way she crouches to assess Wen's pulse, the way she dresses Eric's head wound mid-negotiation — keep her grounded in a register the rest of the script never quite tips into religious abstraction. The performance is the film's quietest, and the second-act scene in which she explains, calmly, what she will do at her appointed time is the cabin's most chilling.
Rupert Grint headshot
Rupert Grint
as Redmond
Grint plays Redmond as the cabin's anti-Bautista: a Boston power-company worker visibly less rehearsed in calm, with a temper that surfaces in the first ten minutes and a Boston-accented hostility the script lets Andrew read against. Shyamalan uses Grint's casting against type — the character is exactly the kind of man the actor's pre-Knock filmography did not predict — and Redmond becomes the figure on whom Andrew's biggest interpretive bet rests.
Abby Quinn headshot
Abby Quinn
as Adriane
Quinn's Adriane is a Washington line cook whose vision of the apocalypse is the most domestic of the four — the catastrophe she has been shown involves children she has never met. The performance leans into a tearful matter-of-factness the cabin scenes need to keep the strangers from collapsing into a single emotional register; Adriane's grief is a different shape than Sabrina's calm or Leonard's gentleness, and Quinn gives the script its fourth distinct moral key.
