The film has taken $41 million in Spain this year, according to Rentrak data cited by Deadline. It passed the year's earlier top Spanish film, Torrente Presidente, a few weekends ago.

It has sold 5.5 million tickets in Spain, the most for any film this year, Deadline reports, citing distributor Elastica and Rentrak.

La Bola Negra has also entered Spain's all-time top 10, at No. 10 with 36.7 million euros, the site says. It is the third highest-grossing Spanish film ever there.

For the calendar year in Spain, it ranks third behind Spider-Man: Brand New Day and The Odyssey, Deadline reports.

The film was written and directed by Javier Calvo and Javier Ambrossi, known as Los Javis, the site says. They won best director at Cannes for it.

Set across three timelines, the film is inspired by Lorca's life and work, The Guardian reports. It focuses on his relationship with Rafael Rodríguez Rapún and his unfinished play La Bola Negra.

A bookseller in the Guardian story says the film's popularity has led to more demand for books about Lorca.

The song La Nieve, written for the film by its star Guitarricadelafuente, reached the top 10 of the Spanish charts, The Guardian says.

Netflix bought the film's US rights for a reported $5 million, Deadline says. It has made $1.2 million in North America.
