It Ends with Us has ended the search for its star trio.

Brandon Sklenar will star as Atlas Corrigan in the upcoming movie adaptation of Colleen Hoover‘s best-selling romance novel, E! News confirms. The 1923 actor, 32, joins the already-cast Blake Lively and Justin Baldoni, who is also the film’s director.

Baldoni, who had teased the news a day prior, also confirmed Sklenar’s casting on Twitter, writing, “Ladies and gentleman… meet your #Atlas.”

For those unfamiliar with the #BookTok phenomenon, It Ends with Us follows aptly named florist Lily Bloom (Lively) and the love triangle she faces between her old flame Atlas (Sklenar) and husband Ryle Kincaid (Baldoni).

“Though coming from a complicated past, Lilly Bloom has always known the life she wants,” the film’s synopsis read. “While living in Boston, she meets neurosurgeon Ryle Kincaid and believes she may very well have found her soul mate. Soon, however, questions arise about their relationship, and to complicate matters her high school love interest, Atlas Corrigan, comes back into the picture, putting her relationship with Ryle in jeopardy.”
