Srdlyo (The Pout-Pout Fish) is a 2026 Australian-American animated adventure fantasy film directed by Ricard Coussot and Rio Harrington from a screenplay by Ellis Allen and Eli Choufani. The film is set to be released in Australia on 1 January 2026.
Srdlyo is an animated family film that will be released in theaters on March 20, 2026 and is based on the popular children's book series by Deborah Deesen, known for its New York Times bestselling status and multiple editions worldwide. The film is an adventure animation filled with humor, fantasy and warmth, aimed at children and the whole family, gathering an all-star ensemble cast behind the voices of the characters.
The story follows Mr. Fish, a grumbling sea fish with a perpetually gloomy expression, and Pip, an energetic and cheerful baby sea dragon, who find themselves at the center of an epic underwater adventure. When their homes are threatened, the two team up to find the legendary Shimmer Fish, which is said to grant wishes and save their home. Along the way, they encounter a variety of ocean creatures — from jellyfish to predatory sharks and starfish — that test both their courage and their bond as friends.
The directorial duo of Ricard Cousseau and Rio Harrington create a colorful, fast-paced, and fun animation that mixes adventure with a lighthearted lesson in friendship, courage, and acceptance—themes that resonate with the original books. The visual style is bright and engaging, aimed at a younger audience, but with enough twists and humor to keep adult companions entertained. The film’s tone ranges from a lighthearted adventure to a heartfelt story that encourages children to overcome fears and seek out friends even where they least expect to find them.
The animated adaptation relies on a strong and diverse voice cast that brings life and personality to the underwater characters:
Nick Offerman like Mr. Fish — nurtured with a constant darkly ironic attitude, whose emotional change is central to the plot development.
Nina Oyama as Pip — full of energy and optimism, Pip is the perfect contrast to Fish and a catalyst for adventure.
Miranda Otto like Marin, a female squid with a strong character and a significant role among the marine inhabitants.
Remy Hii like Benji, an orange squid who brings warmth and a friendly spirit.
Jordin Sparks like Shimmer—the legendary fish whose role is the heart of hope for the heroes.
Amy Sedaris voices the pink dolphins, adding a humorous touch to the film.
Srdlyo is a warm, entertaining, and family-friendly animated film that transforms a beloved children's book into a full-blown underwater odyssey. With its mix of adventure, comedy, and sentimental moments, the film is an ideal choice for children and their families looking for a story about friendship, courage, and finding joy in dark and unpleasant times.
