"Stephanie is a survivor. She continues to test this in herself. Everything she puts herself through proves that," Lively told Bustle.
"She puts herself in extreme circumstances, thinking she's trying to die, but she’s really trying to survive. She is constantly testing her inner strength as her self-worth is regularly undervalued, by her, first and foremost. But she knows, at her core, she’s worth more."

A more dramatic bid to grace the headlines, the actress unfollowed everyone - including husband Ryan Reynolds - and changed her bio to: "What happened to Emily?"
She later started following 28 random accounts under the name of Emily Nelson - the moniker she undertook in the 2018 film.
Lively also took to Twitter to further tease the project by posting a photograph of a cryptic hangman puzzle - drawing further intrigue ahead of the film's release.
