Maria do Mar is a 1930 Portuguese silent drama film, a docufiction, directed by Leitão de Barros.

[1][2] The film is notable not just for its narrative but also for its innovative use of cinematic techniques influenced by German expressionism, Soviet montage, and American filmmaking styles.

It is considered one of the earliest examples of "ethnofiction," where real cultural and social practices are depicted within a fictional framework.

This animosity is further complicated by the romantic relationship between Maria do Mar, the daughter of one of the deceased fishermen, and Manuel, Falacha’s son.

Despite their love, the couple faces opposition from their families, mirroring a "Romeo and Juliet" scenario set against the harsh and rugged backdrop of a fishing community.
