Mario Casas Directs Brother Óscar in Bare-Knuckle Drama 'Unguarded'

Warner Bros. Pictures will release Mario Casas' second film as a director, "Unguarded," theatrically in Spain in 2027. Film Factory Entertainment brings the title to market this week at the AFM (American Film Market), handling international sales.

"Unguarded" (Spanish title: "A puño descubierto") stars Mario Casas ("The Invisible Guest," "Cross the Line," "Bird Box Barcelona") and his brother Óscar Casas ("Idols") as underground bare-knuckle MMA fighters. The package carries weight: writer Eduard Sola ("A House on Fire," "Querer"), producer Nostromo Pictures ("The Invisible Guest," "Apocalipsis Z"), and A puño descubierto AIE. Nostromo produces in association with Movistar Plus+ ("Sirāt," "La Bola Negra"), with the participation of HBO Max.

What is the film about?

The synopsis calls it a grounded, high-intensity action drama about brotherhood, guilt and survival. Luis survives in the world of underground fighting alongside his brother Daniel, in a fraternal bond described as "as strong as it is fragile." One brother dreams of escape. The other stays trapped.

"Caught between loyalty, necessity and difficult decisions, both must face their own limits," the synopsis runs. "'Unguarded' is a story about brotherhood, sacrifice and the possibility (or impossibility) of escaping an inherited destiny."

Tania Noriega ("Lady Altagracia"), Migdalia H. and Javier Oliveras complete the cast.

How was it shot?

Production ran six and a half weeks from April, largely in lesser-known parts of Barcelona, with some fight scenes lensed on Gran Canaria. Casas shot with two cameras and long takes that hug the actors — some lasting 20 or 30 minutes, a method he says keeps him onscreen as both actor and director and adds realism.

Fight sequences were choreographed to capture the reality of such combat. Óscar Casas trained intensively for months alongside combat-sports professionals before the shoot.

What has the director said?

"This is not a fight movie," Casas said. "It's about how two brothers relate to violence. We are following the characters all the time, creating a real place. What I want is for the shoot to feel alive. I'm very happy to be telling this second story as a director."

That's a revealing quote. An action thriller shot in half-hour takes is an unusual bet, closer to a stage production than a genre assembly line. Casas seems to know it.

Film Factory Director Vicente Canales backed the pairing. "We are delighted to team up again with Nostromo and to accompany Mario Casas on his second film as a director," he said.

"'Unguarded' is an intense, emotional and deeply physical story, powered by the unique chemistry between Mario and Óscar Casas, and we are convinced it will connect strongly with audiences and buyers worldwide," Canales added.

Whether buyers bite at AFM will say much about the market's appetite for Spanish-language prestige action. A 2027 Spanish theatrical release, two streaming platforms already aboard and real brothers playing brothers: the financing logic is sound. The half-hour takes are the gamble.
