NOTE TO READERS: Sunday's Children is a 19-minute short film selected for Cannes's student/emerging director section (La Cinef), not a feature-length theatrical release. This post covers the confirmed facts about the film and how to access it on InfinityTV when available. A full feature-length "how to watch" post will be updated if the film secures wider distribution or a feature-length version is produced.

What Is Sunday's Children?

Sunday's Children is a 2026 short drama film written and directed by Reuben Hamlyn, produced through NYU (New York University) as a student film. It was one of 10 short films selected for La Cinef — the Cannes Film Festival's student filmmaking competition, open to film schools from around the world — from 3,184 submitted entries. Selection for La Cinef is among the most prestigious recognitions available to a student filmmaker internationally.

The film screened in La Cinef Program 3 on May 20, 2026 at the Salle Buñuel in Cannes — the 286-seat screening room at the Palais des Festivals typically used for short film programmes and parallel selection screenings.

The Story

Dennis (Maximilian Isaacs) is a man for whom having children is a central life desire. He spends a weekend falling for Kasia (Blu Hunt), a woman with whom he feels a deep connection. The complication: Kasia believes that a past miscarriage was a sign from God that she was never meant to be a mother. She holds this belief not as grief or rationalisation, but as genuine theological conviction.

The film explores the gulf between Dennis's desire and Kasia's belief — two ways of interpreting the same human experience (the desire for children, the experience of loss) that are fundamentally incompatible. The film's title — Sunday's Children — may reference the folk belief that children born on a Sunday are blessed, or may operate more metaphorically as an image of lives lived in the expectation of gifts that do not arrive.

Reuben Hamlyn describes the film as exploring "generational divides, signs and meaning-making, and the gulf between desire and destiny" — the tension between a secular desire for biological continuity and a faith-based interpretation of reproductive loss.

The film concludes with what is described as "an unforgivable action" — a dramatic escalation whose nature is not detailed in available materials.

The Cast

Maximilian Isaacs plays Dennis. Isaacs is a young American actor whose work in Sunday's Children represents his most prominent festival appearance to date.

Blu Hunt plays Kasia. Hunt is an American actress known for The New Mutants (2020) and Another Life (Netflix, 2019-2021). Her casting — a Native American actress of Lakota Sioux descent playing a character with a specific theological relationship to loss and meaning — brings cultural dimension to the role.

La Cinef at Cannes: What It Means

La Cinef (formerly known as the Cinéfondation) is the section of the Cannes Film Festival dedicated to films produced by film school students from around the world. It was created in 1998 by Festival President Gilles Jacob. Each year, La Cinef selects between 16 and 20 short films from thousands of submissions from film schools across all countries.

Selection for La Cinef is one of the most significant recognitions available to a student filmmaker. The competition identifies early-career directors before their first professional features and creates a direct pathway into the Cannes professional ecosystem — previous La Cinef alumni include directors who went on to feature careers at Cannes and other major festivals.

3,184 films were submitted for the 2026 La Cinef. The selection of 10 short films from that pool represents an acceptance rate of approximately 0.3% — among the most selective processes in world cinema at any level.

Reuben Hamlyn is a British filmmaker studying at NYU. Sunday's Children is his most prominent film to date. The production is a US-UK co-production, reflecting Hamlyn's British origin and NYU base.

The Themes: Desire, Belief, and What We Accept

The central dramatic tension in Sunday's Children — between a man who wants children and a woman who has interpreted her miscarriage as a divine message that she should not have them — addresses two of the most charged areas of contemporary life simultaneously.

Desire for biological parenthood and the psychological weight it carries — for both men and women, though the cultural scripts differ significantly — is a subject that carries enormous weight in people's actual lives. The experience of infertility, pregnancy loss, and the decision about whether to try again is among the most psychologically significant that many people face.

The role of religious belief in reproductive experience — the framework people use to interpret pregnancy loss, whether secular (grief, medical, statistical) or faith-based (meaning, sign, will of God) — is an area where different interpretive systems do not easily reconcile. Kasia's belief is presented not as pathology but as genuine theology: she has interpreted her experience through a specific religious frame and that frame has become load-bearing in her identity.

What Hamlyn does with these two frameworks — and with "an unforgivable action" — is the film's dramatic stakes. A 19-minute film that engages seriously with this material is the kind of work that La Cinef was designed to recognise.

Reuben Hamlyn: An Emerging Director

Reuben Hamlyn (British, NYU film school) has given interviews to Eye For Film and Moveable Fest about Sunday's Children. The film is listed in the official Cannes Film Festival programme for Sunday's Children and can be verified via IMDb — coverage from film criticism outlets that signals recognition of his work at a level unusual for a student short film. The film's British Council registration (it appears in the British Council's Films and Festivals database) confirms its status as an official UK co-production.

Hamlyn's work at Cannes La Cinef places him in a very small cohort of student filmmakers who receive this level of early international attention. The next stage of his career — whether at Cannes, Sundance, SXSW, or elsewhere — will be closely watched by those who followed Sunday's Children.

InfinityTV's 22,000+ live TV channels include film culture programming from both the UK and the United States covering the Cannes La Cinef programme, where Sunday's Children received attention from festival observers.
