Little Fish (2020) is a beautifully melancholic sci-fi romance that explores the fragility of memory and love. Directed by Chad Hartigan, the film presents a haunting near-future where a mysterious neuro-inflammatory disease causes people to lose their memories, erasing their identities and relationships. At its heart is the story of Emma (Olivia Cooke) and Jude (Jack O'Connell), a young couple whose deep bond is tested as the virus begins to unravel the very fabric of their shared history.

The film's strength lies in its intimate, grounded approach to a high-concept premise. Rather than focusing on global catastrophe, it zeroes in on the personal apocalypse of forgetting the person you love. Olivia Cooke delivers a tender and resilient performance as Emma, who desperately clings to evidence of their life together—photos, notes, and rituals—as Jude's memory deteriorates. Jack O'Connell matches her with a portrayal that is both vulnerable and heartbreaking, capturing the confusion and fear of losing one's self.

Hartigan's direction is restrained and atmospheric, using a muted color palette and thoughtful cinematography to create a sense of quiet dread and longing. The narrative moves between past and present, contrasting the vibrant early days of Emma and Jude's romance with the increasingly fragile present. This structural choice emphasizes what is at stake, making their struggle profoundly emotional.

Little Fish is more than a pandemic allegory; it's a poignant meditation on how love is built and sustained through shared memory. It asks what remains of us when our stories are forgotten. For viewers seeking a thoughtful, character-driven drama with sci-fi elements, this film offers a moving and beautifully acted experience that lingers long after the credits roll. Its exploration of devotion in the face of oblivion is both timely and timeless.
