Mudos testigos is a cinematographic collage made from all the surviving material of Colombian silent films, re-editing the images in such a way as to create a single imaginary film: the impossible love story of Efraín and Alicia that traces the convulsive first half of the twentieth century in Colombia. Compiled by the late Luis Ospina and finished posthumously by Jeronimo Atehortúa.

Adaptation of the novel by José María Vargas Vila, a romantic drama that tells about the middle-class Bogota early last century.

This cinematographic work was taken from the theater to the screen after it was premiered on June 21, 1924 by the Adams-Nieva company at the Municipal Theater and withdrawn by the "Junta de censura" (Censorship Board). Only some journalistic testimonies of its existence remain.
