“Lobo Feroz is a loose, revitalised adaptation of Big Bad Wolves. There were many changes that we made when you compare it to the original, given that we added new characters, plot strands and locations, and we introduced and fleshed out new themes teetering between dark comedy and police thriller. The film questions one’s principles, human behaviour and how ambiguous it can be,” the director explained to Cineuropa. “I’m very happy to be able to work with a dream Spanish cast, where everyone demonstrates their enormous talent and commitment in every scene and through every single detail.” The screenplay for the movie – written by Juan Manuel Foode Roma and Eva María Alonso Moreno – follows a police officer on the fringes of the law and a woman seeking revenge. Their paths cross, as they are obsessed with discovering the identity of the murderer behind a string of brutal crimes involving various girls. They are both willing to do whatever it takes to secure a confession, even though they will have to take the law into their own hands in order to do so. At the same time, a model detective will do his utmost to avoid irreparable errors being made and to ensure that this desperate search for the truth does not transform into the fiercest of wolves.
