Agustí Villaronga Riutort (Catalan pronunciation: [əɣusˈti βiʎəˈɾoŋɡə]; 4 March 1953 – 22 January 2023)[1][2] was a Spanish film director, screenwriter and actor.

His grandparents were itinerant puppeteers and his father was a child of the Spanish Civil War, a background that would resurface repeatedly in the director's filmography.

The plot follows a former Nazi doctor, now paralyzed and depending on an iron lung to live, who begins to be taken care of by a young man, one of the children he abused during the war.

In a Glass Cage already shows some of the key elements in Villaronga's filmography: a disturbed childhood marked by violence, an early discovery of sexuality.

[15] In 2000, Villaronga came back with a project of his own: El mar, a story set in Mallorca about three former childhood friends, traumatized by the violence they experienced during the Spanish Civil War, that are reunited ten years later as young adults.

[citation needed] Villaronga followed Black Bread's success with A Letter to Evita, a TV miniseries co-produced by TV3, which recounts a real episode in the life of Eva Perón while visiting Spain in the late 1940s.
