The Dark Side of the Heart (Spanish: El lado oscuro del corazón) is a 1992 Argentine surrealist romantic drama film written and directed by Eliseo Subiela.

[4] Oliverio (Grandinetti), a Bohemian poet, travels through Buenos Aires with his friends, harassed by Death, looking for a woman capable of “flying”.

In the course of the film, the poetry of Mario Benedetti, Juan Gelman and Oliverio Girondo is seen intermingled with the thickest places of Argentine and Uruguayan artistic daily life.

The story unfolds in the comings and goings of Oliverio, through his world, in which, exchanging food for poetry, or asking for coins on street corners, seeing Mario Benedetti reciting his poems in German, seeing Genetic sculptures, talking to cows, and conversing with death seem to be part of any given day in the life of a poet.

A Spanish-Argentine co-production, it was again written and directed by Eliseo Subiela, with Darío Grandinetti and Sandra Ballesteros reprising their roles from the original film.
