The Danza: Patricia Alvarez is played by Patricia Velásquez.
Dueling Works: With the 2019 Guatemalan film La Llorona (released in 2020 in the United States through the Shudder streaming service). While Curse got much higher exposure through being a major Hollywood release (and turned a very strong profit with $123 million against a $9 million budget), the Guatemalan film was much better received with superlative reviews (including a Golden Globe nomination) and higher audience scores than Curse, which was criticized for reducing its titular figure to a generic horror monster.
The Shelf of Movie Languishment: Was released in 2019, but the end credits reveal that the film was actually completed in 2018.
Fake American: Venezuelan Patricia Velásquez as American Patricia Alvarez.
