Little Fish follows a young couple racing against a spreading memory-loss illness that threatens to erase everything they have built together.
What is Little Fish about?
Emma and Jude are newlyweds still learning each other's habits when a strange illness begins spreading, one that strips away memories with no clear pattern to who it strikes or when. There is no warning and no cure, only the slow, frightening realization that a shared life can unravel one forgotten detail at a time. When Jude starts losing pieces of his own memory, the couple is forced to find ways to hold onto their relationship using notes, routines, and each other's patience, even as the disease makes that harder by the day. The film moves between their present struggle and glimpses of how they met and fell for each other, using that contrast to ask what actually keeps two people bound together once memory itself can no longer be trusted.
About the cast
Olivia Cooke and Jack O'Connell play Emma and Jude, carrying most of the film's emotional weight through a relationship built almost entirely on small, quiet moments rather than big dramatic turns. Raúl Castillo, SoKo, David Lennon, and Mackenzie Cardwell round out the supporting cast. Director Chad Hartigan keeps the camera close and patient, letting the two leads' chemistry do the work of showing a marriage under a kind of pressure neither partner can fully explain to the other.
Context & significance
Little Fish blends drama and romance with a speculative illness premise, using science-fiction elements sparingly rather than as the film's main draw. Released in 2021 and produced across Canada and the United States, it belongs to a small run of pandemic-adjacent dramas that used a fictional outbreak to explore loss and connection rather than aiming for disaster-movie scale. The approach keeps the story grounded in one couple's daily life, with the wider illness mostly felt through its effect on their relationship rather than through large-scale spectacle.
