Rosaline is a 2022 American romantic comedy film directed by Karen Maine, written by Scott Neustadter and Michael H. Weber, and starring Kaitlyn Dever, Isabela Merced, Kyle Allen, Sean Teale, Christopher McDonald, Minnie Driver, and Bradley Whitford.

It is based on the 2012 young adult novel When You Were Mine by Rebecca Serle, which in turn was inspired by William Shakespeare's Romeo and Juliet.

Rosaline and Dario infiltrate the Montague estate, intending to stop the wedding, but are caught by guards and escape on horseback.

Rosaline realizes she did not truly love Romeo and sends his letters back to Juliet, but the message is intercepted by Tybalt.

[15][16] Writing for IndieWire, Samantha Bergeson stated that "Rosaline in part acts as a who's-who of Gen Z Hollywood", citing Dever, Merced, and Allen starring in the upcoming films Ticket to Paradise, Madame Web, and the now cancelled live-action Masters of the Universe, respectively.

[18][19] The film was released on October 14, 2022, on Hulu in the United States, Disney+ internationally, Disney+ Hotstar in Southeast Asia and Star+ in Latin America.

It is no longer available on Disney+ in the US, but it is currently available digitally on other platforms, including Amazon Prime Video, Vudu and Google Play as of September 26, 2023.

The website's consensus reads: "Rosaline covers well-trod territory, but Kaitlyn Dever's engaging performance in the title role makes this period romance easy to love.

"[24] Metacritic assigned the film a weighted average score of 61 out of 100 based on 17 critics, indicating "generally favorable reviews".
