Biography

Roy was born in 1988 and Arturo, his younger brother, was born in 1990. Both studied film in university. They first ideated their independent stop-motion studio Cinema Fantasma when preparing for Arturo's thesis film Pluto and the Planets, and officially launched it not long after.[1] They are considered proteges of del Toro.[2][3]

They were mentored by del Toro and Screen Novelties, among others, while working to produce their first official film, stop-motion Cubist short Revoltoso. The short, which took the duo five years, is about a boar who finds a film camera.[4][5] The short was also blurbed by Jorge R. Gutierrez.[6][7] During this time, they also produced 7 short stop-motion films for Cartoon Network Latin America, based on existing Cartoon Network shows and called "C Sides".[1]

They then went on to direct, write, and produce Frankelda's Book of Spooks. The pilot was released by Cartoon Network in 2019.[8] After HBO Max decided to produce it, the series became a musical, and it premiered in 2021.[9] It then made its English-language debut in 2023.[10] It received positive reviews from critics.[11]

They then planned to create a half-an-hour special prequel episode of Frankelda's Book of Spooks for HBO Max Latin America called Frankelda and the Prince of Spooks.[12] The film, however, soon grew in length to a full-length movie, which became known as I Am Frankelda and became the first feature-length stop-motion film from Mexico, premiering at the Annecy International Animation Film Festival in 2025.[13][14] That same year, it was released in Mexico.[14] It was purchased by Netflix for release in 2026.[2] It has received positive reviews from critics, including at Empire[15] and IndieWire.[16]

They also produced stop-motion series Women Wearing Shoulder Pads for Adult Swim.[17][18][19]

They have announced two other feature films, The Ballad of the Phoenix, which was originally meant to be created before I Am Frankelda,[20][21] and The Bee Revolution.[22] As of June 2026, they are in pre-production for The Ballad of the Phoenix.[23]
