When the Lillian Gish film THE WHITE SISTER was released in Argentina two musical themes were written adopting the film's name in its Spanish translation: LA MONJITA.
The film was released in either 1924 or 1925, since there was no MGM distribution branch in Argentina yet although after it opened in 1927, they would reissue it.

The other one is a tango by Nicolás Di Masi, which was recorded by the "Orquesta Típica Victor" (an successful ensemble from the recording label, which lasted for 20 years... and never performed in front of an audience!); a recording that I have.
Here is a bandoneon solo performance of LA MONJITA. However, after listening to the Victor recording, this tango seems to be altogether a different one:
