After hitting the red carpet in support of her husband Ryan Reynolds' "Deadpool & Wolverine," Blake Lively is finally back on the big screen with Sony's "It Ends With Us," an adaptation of author Colleen Hoover's popular romance novel.

“It Ends With Us” grossed $7 million at the box office in previews on Thursday. It’s expected to gross between $25 million and $35 million, though some estimates put it even higher, at $40 million to $50 million. Fans of the book, which has become massively popular on TikTok in recent years, could turn out in bigger numbers than expected. Female audiences in particular could drive ticket sales, and it’s possible that “It Ends With Us”’s Friday opening could even beat out “Deadpool & Wolverine” for the day.

However, the Marvel blockbuster is expected to take home the box office for a third straight week, adding $47 million to $50 million. The record-breaking, R-rated MCU film, starring Reynolds and Hugh Jackman, is set to surpass $1 billion worldwide in the coming days.

"It Ends With Us" stars Lively as Lily Bloom, a florist who meets neurosurgeon Ryle Kincaid, played by star and director Justin Baldoni. They begin a relationship, but then Lily runs into her childhood friend Atlas Corrigan (Brandon Sklenar), making Ryle jealous. The three have a complicated relationship with each other, and Lily must decide who she ends up with. The film only cost $25 million to produce, so it could turn a tidy profit by the end of its box office run.
