Amber Tamblyn (Megan) and Kate Mara (Kristi) appear in the first act as two hikers Ralston meets before his accident. Their casting is crucial for two reasons.

Clémence Poésy (Rana) plays Ralston’s ex-girlfriend, appearing only in flashbacks and a key hallucination. Poésy, known for her ethereal quality (Fleur Delacour in Harry Potter ), embodies a lost, romanticized past. Her scenes are shot with a handheld, golden-hued intimacy—contrasting the canyon’s harsh digital clarity. 127 hours cast

The casting choice is deliberate: Poésy is French, foreign, slightly unknowable. This distances Rana from the “real” world of the canyon, framing her as an idealized memory. In the film’s most surreal sequence, Ralston hallucinates attending his own funeral, then a party where he makes love to Rana under a spotlight. Poésy’s performance is gentle but detached, as if she is a hologram. Boyle casts her not as a character but as a regret mechanism —the life Ralston sacrificed for adrenaline. Her final appearance, where she holds a baby that may or may not be his, injects ambiguous hope. Poésy’s innate otherworldliness makes this ambiguity believable.

Lizzy Caplan appears in a single scene as Sonja, Ralston’s sister, delivering a voicemail about a birthday party.

Williams’ sturdy paternalism and Burton’s maternal anxiety are distilled into a single image. Boyle’s choice to not cast major stars as parents reinforces that Ralston’s isolation is self-imposed; his family are ghosts by his own design. Poésy, known for her ethereal quality (Fleur Delacour
