A teaser trailer has been released for the film The Summer Book, based on Tove Jansson's 1972 novel. Deadline reported that the family drama, directed by Charlie McDowell, will star Glenn Close "in the role of an artist who bonds and heals with her nine-year granddaughter, played by newcomer Emily Matthews, in the wake of a family tragedy over the course of a summer." Shooting took place on an island near Kotka, Finland, during the summer of 2023.
The film will have its world premiere as a special presentation at the BFI London Film Festival in October. The English-language adaptation is produced by Stille Production and Free Range Film, High Frequency Entertainment in the U.S., Finnish production house Helsinki Filmi and Case Study Films--co-founded by McDowell and his wife, Lily Collins--in association with MUV Capital, Finnish Impact Film Fund, and Eye Eye Pictures.
