Samhain: Arriate Studio and ¡Viva Calavera! Collaborate on Ambitious Animated Feature Film

Spain’s Arriate Studio and Mexico’s renowned animation house ¡Viva Calavera! have officially unveiled their partnership to produce an animated feature film titled Samhain. The project, which is currently in active development, serves as a high-profile adaptation of the acclaimed 2024 graphic novel authored by Lobón Leal. By blending 2D and 3D animation techniques, the production aims to deliver a 90-minute fantasy adventure tailored for a young adult audience. The announcement, timed to coincide with the Halloween season, underscores a growing trend of international co-productions between emerging European studios and established Latin American creative powerhouses.

The Narrative Foundation and Creative Vision

At its core, Samhain presents a subversive take on the commercialization of holiday traditions. The story centers on Mika, a young, magical creature living in a vibrant forest. Driven by a longing to experience the fabled “land of candy,” Mika, alongside her brother Miko and their companion Frigo, inadvertently crosses a boundary into the human world. What they discover is a bleak, monochromatic landscape where nature and magic have been commodified for profit.

The film introduces two central antagonists who serve as allegorical figures for the modern retail era: Miss Allsaints, a witch who harvests magic for financial gain, and Don Papi, a satirical reimagining of Santa Claus. Through this narrative, directors Lobón Leal and María Luquero intend to explore the sociological impact of how the world’s most celebrated holidays—Halloween and Christmas—have evolved into massive, industrial-scale businesses. Leal, who is also spearheading the art direction, is adapting his own 308-page graphic novel, which is noted for its stark visual contrast between the lush, magical forest and the industrialized wasteland of the human world.

A Transatlantic Partnership

The production of Samhain marks a significant milestone for Arriate Studio, based in Chiclana de la Frontera, Cádiz. While the studio has previously focused on project development and illustrated-book publishing, this film represents its first venture into feature-length animation. The studio was founded by Lobón Leal, María Luquero, and executive producer Cristina Fernández—professionals with deep experience in the Spanish animation landscape, having contributed to major intellectual properties such as the internationally recognized children’s series Pocoyo and the successful film franchise Tad the Lost Explorer.

The partnership with ¡Viva Calavera!, founded in 2014 by the elusive and masked brothers known as Los Hermanos Calavera, brings a distinct aesthetic and technical pedigree to the table. The Mexican studio gained international attention for its work on Cartoon Network Latin America’s Rey Mysterio vs. The Darkness, a series that successfully synthesized elements of lucha libre, supernatural lore, and anime-inspired action. By bridging the gap between the Andalusian coast and Mexico, the two studios are positioning Samhain as a project that transcends geographical borders, utilizing the distinct creative sensibilities of both regions to craft a globally appealing narrative.

Chronology and Development Timeline

The genesis of Samhain can be traced back to the publication of the original graphic novel in 2024. Following the book’s positive critical reception, the creative team at Arriate Studio moved quickly to initiate the transition from print to screen. Throughout 2025 and 2026, the project moved through the stages of script development, character design, and visual world-building.

The debut of the teaser trailer on October 31, 2026, marks the project’s transition from a developmental concept to a public-facing production. While a formal release date remains unannounced, the project is currently in the pre-production and early production phases. The involvement of Global Music Branding, which composed the music for the teaser, signals that the audio-visual identity of the film is already being solidified.

Technical Approach and Artistic Methodology

The choice to utilize a hybrid of 2D and 3D animation is a deliberate stylistic decision intended to enhance the thematic contrast within the story. The "magical" elements of the world are expected to utilize fluid, hand-drawn 2D techniques to evoke a sense of organic wonder, while the "human" world—controlled by corporate entities like Miss Allsaints and Don Papi—will likely be rendered with the sharper, more rigid geometry associated with 3D animation.

This dual-aesthetic approach is intended to reinforce the film’s critique of industrialization. As noted by the creative leads, the goal is to ensure that the visual language of the film remains faithful to the graphic novel’s specific use of color and black-and-white imagery, which was essential in the source material to delineate between different environments.

Implications for the Global Animation Industry

The collaboration on Samhain is indicative of a broader shift in the global animation sector. For years, the industry was dominated by major hubs in Madrid and Barcelona in Spain, and Mexico City in Latin America. However, the success of Arriate Studio—a company based in the smaller municipality of Chiclana de la Frontera—proves that regional production houses are increasingly capable of securing international partnerships and producing high-quality feature content.

By targeting a young adult audience, the film also addresses a growing market demand for animation that moves beyond traditional family-friendly fare. The thematic focus on environmental exploitation and the commercialization of culture suggests that the film is intended to spark conversation, a strategy that has proven successful for other animated films in recent years that seek to engage older demographics through deeper, more complex narratives.

Official Statements and Industry Reaction

Reflecting on the milestone, the founders of Arriate Studio expressed their commitment to decentralizing the Spanish animation industry: "Building original stories from the periphery, bringing creative projects to life from our corner of the world, and watching them grow hand in hand with friends is what makes this journey so special and worthwhile."

Los Hermanos Calavera offered a similarly enthusiastic perspective on the cross-continental synergy, stating, "Collaborating with Arriate on Samhain has been fantastic. Across an ocean, we share sensibilities and the hunger to make something interesting and unique. Lobón’s art and aesthetic sense work very well with our animation style, and we’re excited to bring this story to life beyond the comic book pages."

Analysis: Why Samhain Matters

The development of Samhain is noteworthy for three primary reasons. First, it represents an artist-led initiative that maintains creative control through the original author’s involvement as both director and art director. This is a crucial factor in ensuring the integrity of the original source material.

Second, the film’s critique of holiday commercialization is timely. As global audiences grow increasingly aware of the environmental and social costs of consumerism, a film that explores these themes through the lens of folklore and fantasy is likely to resonate with contemporary viewers.

Third, the project serves as a case study for successful international co-production. By leveraging the tax incentives and creative talent of Spain alongside the technical expertise and narrative energy of Mexico, the producers are mitigating the financial risks inherent in independent animated features.

As the project continues to take shape, industry analysts will be watching closely to see how the combination of 2D and 3D elements is balanced and whether the film can successfully translate its graphic novel success into a cinematic experience that appeals to the global market. While the wait for a release date continues, the initial materials released by the studios suggest that Samhain is a project of significant ambition and artistic merit, setting a high bar for independent animated features in the coming years.
