Acclaimed Drama THE SUMMER BOOK Gets Trailer, Poster, Theatrical Release Date

Music Box Films has released the official trailer and poster for their upcoming drama THE SUMMER BOOK, which will launch in select US theaters on September 19th, 2025. The film world premiered at the 2024 BFI London Film Festival.

The Summer Book is directed by Charlie McDowell, written by Robert Jones, and stars Glenn Close, Emily Matthews, and Anders Danielsen Lie. It is based on Tove Jansson's 1972 novel of the same name.

In the film, nine-year-old Sophia (Emily Matthews) spends the summers at her family’s seasonal home on a tranquil isle in the Gulf of Finland, but this will be the first summer without her mother. Her father (Anders Danielsen Lie) remains numbed by grief, while her grandmother (Glenn Close) guides her on a giddy, winding path towards young adulthood.

With a sense of infinite possibility and a tender regard for the wonders of the natural world, Sophia and her grandmother explore the terrain, celebrate midsommar, and test the limits of faith in the face of life’s many storms.

We’ve added the release date to our In Theaters Calendar. Check out the new official trailer and poster below.
