For a few years, Mario Casas was less an actor than a bedroom poster. Hache, the leather-jacketed street racer of Tres metros sobre el cielo, turned a young Galician into the face every Spanish teenager could draw from memory, and the industry treated him accordingly: handsome, bankable, not to be taken too seriously. The rest of his career reads as a long, stubborn answer to that verdict. He starved himself for a concentration camp photographer, played a killer who never meant to kill, learned contemporary dance to play a man hiding his sexuality in the Netherlands, and eventually stepped behind the camera to direct his own younger brother. The heartthrob is still there when the marketing needs him. The more interesting question is what he has done with the leverage.

The biography behind the poster is less glossy than the poster suggested. Casas was born in A Coruña on 12 June 1986, the eldest of five children of Ramón Casas, a cabinetmaker who was 19 when his son arrived, and Heidi Sierra, who was 17. The family moved to Catalonia when he was four, and he grew up between Martorell and Esparreguera, on the industrial edge of Barcelona. As a child he filmed commercials for Cola Cao, Scalextric and Telepizza, the kind of work that pays for school shoes rather than launching careers. At seventeen or eighteen the whole family moved to Madrid so that he could chase acting properly, and he combined odd jobs with classes at the Cristina Rota school, the training ground of a generation of Spanish performers. Of his four siblings, Óscar would follow him into the profession, often playing younger versions of Mario’s characters before building a name of his own.

The first doors opened quickly. After bit parts in Motivos personales and Obsesión, he landed a regular role in the teen series SMS, sin miedo a soñar in 2006, and the same year Antonio Banderas gave him his film debut in El camino de los ingleses. Television made him famous. As the police officer Aitor Carrasco in the Antena 3 series Los hombres de Paco, which he played from 2007 to 2010, he was one corner of a love triangle with Hugo Silva and Michelle Jenner that kept millions of viewers tuning in on weeknights. In 2009 two comedies he headlined, Fuga de cerebros and Mentiras y gordas, each topped the Spanish box office on their opening weekends.

Then came Hache. Fernando González Molina’s adaptation of Federico Moccia’s novel Tres metros sobre el cielo opened in December 2010, paired Casas with María Valverde, and became the highest-grossing Spanish film of the year. The sequel, Tengo ganas de ti, followed in 2012. Between the two, Casas was also the lead of the Antena 3 adventure series El barco with Blanca Suárez, and his image, shirtless more often than not, became a commercial asset in its own right.

What is easy to forget is how quickly he started spending that capital elsewhere. In 2012 he joined the anti-drug squad thriller Grupo 7 for Alberto Rodríguez, a director whose films have nothing to do with teenage romance, and played a young man from the margins opposite Ángela Molina in Paco Cabezas’s Carne de neón. La mula, shot years earlier and finally released in 2013, earned him the Silver Biznaga for best actor at the Málaga Film Festival. Álex de la Iglesia used him three times, in Las brujas de Zugarramurdi, Mi gran noche and El bar, and the first two brought him Feroz awards for best supporting actor, the critics’ prize that had been slower than the public to notice him. He tried English-language work too, with Eden and The 33, the Chilean mining drama in which he shared the screen with Antonio Banderas and Juliette Binoche.

The second half of the 2010s mixed commercial muscle with physical transformation. Palmeras en la nieve, the colonial romance González Molina set in Spanish Guinea, reached number one at the Spanish box office in December 2015, ahead of Star Wars: The Force Awakens. Oriol Paulo’s thriller Contratiempo, in which he played the businessman Adrián Doria, drew mixed reviews at home and then became an unlikely export, grossing about 3.9 million dollars in Spain and more than 172 million yuan in China. For El fotógrafo de Mauthausen, the story of the Catalan photographer Francesc Boix, who smuggled evidence of Nazi crimes out of the Austrian camp, he lost around twelve kilos. The role that finally settled the argument arrived in 2020. In David Victori’s No matarás, a thriller about a mild, obedient man dragged into one night of violence, Casas played Dani with a nervous restraint that his earlier roles never asked for. It won him the Goya for best actor, along with the Feroz and the Gaudí.

The critical problem with Mario Casas has never been talent so much as volume. Few leading men in Europe work as steadily, and the list since that Goya includes plenty of efficient genre product: the Netflix films Hogar and El practicante, the Oriol Paulo series El inocente, the spin-off Bird Box Barcelona, and this year the Prime Video spy thriller Zeta, which critics found overlong and over-explained even as it climbed to number one in close to thirty countries. His defenders argue that this is exactly how a Spanish star keeps the industry’s financing machine turning. His sceptics point out that the performances people remember, from No matarás to Muy lejos, came in smaller films that needed his name more than he needed them. Both camps are describing the same strategy.

His move into directing gave that strategy a direction. Mi soledad tiene alas, which he wrote with the Belgian actress Déborah François and released in August 2023, is set in Barcelona’s graffiti scene and stars Óscar Casas, a project Fotogramas described as a love letter from Mario to his brother. A year later he played the enigmatic N in Rodrigo Cortés’s Escape, a film produced with Martin Scorsese‘s backing, and his performance was among the most praised aspects of the release. In 2025 he returned to romance for the first time in a decade with Olga Osorio’s El secreto del orfebre, opposite Michelle Jenner, his screen partner from Los hombres de Paco.

The strongest work of this period came from an unlikely source. Muy lejos, the Catalan-language debut feature of Gerard Oms, his acting coach since No matarás, follows Sergio, an Espanyol supporter who travels to Utrecht in 2008 for a football match, fakes a panic attack to avoid flying home, and slowly begins to face his own queer identity. Casas prepared with a month of contemporary dance classes and studied performances of repressed men by Heath Ledger, Josh O’Connor and Matthias Schoenaerts. The film won him a second Silver Biznaga at Málaga in March 2025 and his second Gaudí for best actor in February 2026, along with nominations at the Feroz, the Actors and Actresses Union awards and the Goya, where José Ramón Soroiz took the prize for Maspalomas. In the autumn of 2025 he also carried Manuel Gómez Pereira’s La cena, playing a young Francoist lieutenant ordered to stage a victory banquet at Madrid’s Hotel Palace with the help of Republican prisoners who happen to be expert cooks. It opened at number one and passed three million euros and half a million viewers.

2026 has been his busiest year yet. Zeta, directed by Dani de la Torre and co-starring Luis Zahera, premiered on Prime Video on 20 March with Casas as a Spanish intelligence agent hunting a missing colleague; its reach was enough for the platform to confirm Zeta 2 in June, with the action moving to Thailand, where a group of Spanish tourists face the death penalty after a drug raid, and filming scheduled to start in September. On 12 June Netflix released Oriol Paulo’s En nombre de otro, in which he plays David, a man who assumes a missing person’s identity during a nationwide blackout. The film reunited him on screen with Blanca Suárez for the first time in six years, alongside Eduard Fernández, Alexandra Jiménez and Nicolás Francella.

His private life has been tabloid material since his early twenties, and he has rarely fed it himself. He was in a relationship with María Valverde, his co-star in the Hache films, from 2010 to 2014, later with Berta Vázquez after Palmeras en la nieve, and with Blanca Suárez from 2018 until the couple separated in 2019. The relationship that shapes his work most visibly is with his brother Óscar, who has shared projects with him since the series Instinto.

That bond is the centre of what comes next. In April 2026 Casas began shooting A puño descubierto, his second feature as director, co-written with Eduard Sola and filmed in the less touristy corners of Barcelona and in Gran Canaria. Óscar Casas plays Luis, who survives in underground bare-knuckle fighting alongside his brother Daniel, one of them trying to get out while the other stays trapped. Produced by Nostromo Pictures with Movistar Plus+, the film is set for a theatrical-only release through Warner Bros. Pictures in 2027. The boy on the poster now decides where the camera goes, and he has chosen to point it at his brother’s fists.
