From NetFlix:

Francis Ford Coppola writes, directs and produces this captivating drama that centers on the relationship between Bennie (Alden Ehrenreich) and Tetro (Vincent Gallo), two brothers who reunite in Buenos Aires after a 10-year estrangement. Maribel Verdu, Klaus Maria Brandauer, Carmen Maura and Rodrigo de la Serna also star in this moving tale loosely inspired by Coppola’s own experiences growing up in a creative Argentine-Italian family.

Wikipedia tells us that in February 2007, director Francis Ford Coppola announced that he would produce and direct the film Tetro, based on a script that he had written while editing Youth Without Youth. There is no mention of whether the plot has anything at all to do with events in the life of the director.

While at times a bit “artsy-fartsy”, the story is compelling and includes some plot surprises. Filming is in black and white except when a character (almost always Tetro) is having a flashback or when some unusual entertainment is happening. Those colored episodes are theatrical, often strange, and involve opera or ballet acting out fantasies or flashbacks.

None of the actors were familiar to me. Alden Ehrenreich was 20 when he made the film. As a smiling, naive, virginal young man he is appealing. After the plot twist he does not seem to carry his part well. In fact for me the last part of the film somewhat fell apart.

At the very least I do not regret having seen the film.
