Escenas Míticas: Sectas – Los sin nombre

Published on April 4, 2026

“Los sin nombre” is not only a cult classic in Spanish cinema but also gained international recognition, winning the best film award at the Sitges Festival, where its originality shone and established director Jaume Balagueró as a filmmaker to watch within both domestic and global horror genres.

For the next two decades, Balagueró confirmed his position as one of the leading figures in Spanish horror cinema in the 21st century. “Los sin nombre,” his debut film, was preceded a couple of short films that hinted at the stylistic patterns he would further develop in his subsequent works.

Following “Los sin nombre,” Balagueró released films like “Darkness” and “Frágiles,” which leaned more towards Anglo-Saxon horror than traditional Spanish horror. He also produced a standout episode in the anthology “Historias para no dormir,” titled “Para entrar a vivir.” However, it was “REC,” without a doubt, that became his most successful film, achieving such impact that it even inspired a Hollywood remake, followed impactful thriller “Mientras duermes.”

In recent years, while Balagueró has explored new territories in fantastic horror with films like “Musa” and “Venus,” he has not recaptured the heights of his earlier works. This was particularly evident in two of the three sequels to “REC,” specifically the first and third installments. Anticipation is building for his next return to the genre, set to arrive in 2027, titled “Hay alguien en el jardín.”

“Los sin nombre” was part of a wave of new Spanish horror, alongside notable titles like “Tesis” and “Abre los ojos,” ábar, with whom Balagueró shared a penchant for surprise endings reminiscent of M. Night Shyamalan’s influence seen in “The Sixth Sense,” a constant throughout his future films.

In fact, Balagueró altered the ending of the movie, which was adapted from a novel of the same title -popular British horror author Ramsey Campbell. This change remained a closely guarded secret, known only to a select few on the production team, as Balagueró aimed to prevent any leaks. He also toned down several scenes that were initially intended to be more explicit and violent.

“Los sin nombre” was considered a part of what became known as “proto-urban folk,” encapsulating the clash of the archaic with the modern in folk horror. This thematic exploration is seen in seminal works like “The Wicker Man” and echoed in films like Ari Aster’s “Midsommar,” but translated into an urban context.

To achieve an authentic feel, Balagueró insisted on filming in real abandoned locations, a practice he would replicate in later projects, such as hospitals, factories, and defunct industrial sites. This choice helped foster a more tangible realism than studio settings, imparting the film with a grim and even decaying atmosphere.

The outcome was remarkable, receiving critical acclaim and achieving a solid box office performance with a gross of 4 million euros on a budget of just 900,000 euros. Moreover, it influenced films beyond Spain, inspiring a diverse range of works from “The Ring” and “Session 9” to “El orfanato” and “Martyrs.” Last year, a six-episode miniseries also titled “Los sin nombre” premiered, presenting a fresh adaptation rather than a straightforward remake.

Despite being Balagueró’s film debut, “Los sin nombre” boasted a recognizable cast in Spanish cinema, including Karra Elejalde, Tristán Ulloa, Emma Valarasau, and Carlos Lasarte. In his later films, he would work with more international ensembles, as evidenced by “Darkness” and “Frágiles,” both shot in English.
