Actress Sadie Sink said her experience on "Stranger Things" prepared her for her role in the Marvel film "Spider-Man: Brand New Day" [1].

Sink's transition from a hit streaming series to a major cinematic franchise highlights the growing trend of casting established young stars from high-profile television dramas to lead blockbuster films.

Speaking at the film's premiere in Los Angeles, Sink said she was cast in the project without having to audition [1, 2]. She said that the intense and character-driven nature of her work on "Stranger Things" provided her with the confidence and specific skill set required for the Marvel Cinematic Universe [2, 4].

Sink also said her co-star, Tom Holland, helped her feel at home on the set during production [3, 4]. The actress has previously shared some of the secrets regarding her role with her former castmates from "Stranger Things" [2].

While reports regarding the timing of her character's reveal vary, some accounts suggest she shared details at the Los Angeles premiere, while other reports indicate she did not know the specifics of her role until she arrived on set [2, 3].

Sadie Sink said she was cast without auditioning.

Sink's casting without an audition reflects the industry's current reliance on 'proven' talent from streaming hits to mitigate risk in high-budget franchise filmmaking. By leveraging the existing fan base of "Stranger Things," Marvel is utilizing a cross-platform casting strategy to ensure a built-in audience for the new Spider-Man installment.
