[1] Coll was assistant director on the acclaimed 1968 movie Palo y hueso, directed by Nicolás Sarquís and starring Héctor da Rosa and Miguel Ligero.
For his 2001 movie Cicatrices (Scars), based on the novel of the same name by Juan José Saer, he was nominated for the 2002 Silver Condor award for Best Screenplay Adaptation at the Mar del Plata Film Festival.
[3] The movie starred Omar Fantini, Raul Kreig, Pablo Di Crocce, Monica Galan, Maria Leal and Vando Villamil.
[4] A critic said of the movie "Coll's film is not easy to pigeonhole: it revolutionizes the visual language, and yet openly avoids clichés of cinema in recent decades".
The film crew was based in a small town called Fortin Olmos, where a group of worker priests from the Congregation of the Brothers de Foucauld had settled a few years earlier and established a farm cooperative.
