Little Fish (2020) is a beautifully crafted sci-fi romance drama that explores profound questions of love and identity against the backdrop of a global pandemic—one that erases memories rather than lives. Directed by Chad Hartigan, the film stars Olivia Cooke and Jack O'Connell as Emma and Jude, a young couple whose relationship is tested as a mysterious neuro-inflammatory disease spreads, causing people to lose their memories and, ultimately, their sense of self.

The narrative unfolds with emotional precision, blending intimate character moments with the eerie, slow-burn tension of a world unraveling. Cooke and O'Connell deliver deeply moving performances, capturing the desperation and tenderness of two people clinging to each other as the foundations of their shared history disappear. Hartigan's direction is restrained yet powerful, using the sci-fi premise not for spectacle but as a metaphor for the fragility of human connection and the stories that define us.

What makes Little Fish particularly compelling is its focus on the small, everyday details of a relationship—photographs, inside jokes, shared routines—and how these become battlegrounds against oblivion. The film’s melancholic tone is balanced by moments of genuine warmth and hope, asking whether love can exist beyond memory. For viewers seeking a thoughtful, character-driven story that resonates with contemporary anxieties about loss and preservation, Little Fish is a must-watch. Its poignant exploration of what remains when everything else is forgotten makes it a standout in the genre.
