@cinemapickkss: Sam Raimi prioritized the casting of Rachel McAdams for this production following their previous collaboration on Doctor Strange in the Multiverse of Madness (2022). He sought to maximize the performer's range after observing her technical proficiency during their prior film project. The director stated, "She was the perfect person because she's such a brilliant actress. I had a chance to work with her on my last film and saw how talented she was and actually underutilized, and I promised myself that I would work with her again. And then this film came up, and her warmth is wonderful." Australian survival expert Kylie Furneaux consulted on the production to ensure technical accuracy regarding wilderness endurance. The consultant engineered specific island camp set pieces and instructed Rachel McAdams and Dylan O'Brien in functional survival methods. These training sessions prioritized the physical execution of fire-making and water collection techniques.
