British actress Charlie Blackwood stars in festival hit ‘Sal Azul’
British actress Charlie Blackwood, known for her powerful performances in ‘Matriarch’ and ‘Toxica’, takes centre stage in the new character-driven film ‘Sal Azul’. Premiering at the prestigious Monterrey International Film Festival in Mexico, ‘Sal Azul’ (which translates as ‘Blue Salt’) has already attracted critical attention, with Variety selecting it as one of the 10 most outstanding films in the festival. Featuring Charlie in the lead role as Connie, alongside actors Gustavo Sánchez Parra and Enrique Arreola, the movie delves into themes of manipulation and toxic relationships. Here Charlie tells us about the importance of encouraging emotionally healthy relationships, finding hope in darkness, and the joys of filming in Mexico.
What’s the storyline of ‘Sal Azul’?
“’Sal Azul’ follows the emotional and psychological journey of two people trapped in a toxic relationship. My character, Connie, is in an intense relationship with a man who gradually isolates and controls her. The film explores the dynamics of how manipulation can sneak into even the closest relationships and how difficult it can be to see the truth when you’re deep in it. It’s a raw, emotional story about breaking free and reclaiming your identity.”
You play the lead role of Connie in the film. What can you tell us about her character?
“Connie is a complex mix of strength and vulnerability. As her relationship progresses, we witness how manipulation breaks her down. What I love about Connie is her resilience – no matter how far she falls, she finds the courage to stand up again. She’s a survivor, and I think that resilience is something a lot of people can relate to.”
What drew you to this challenging role?
“Connie’s arc of self-discovery and empowerment really drew me to the role. Her emotional journey is a rollercoaster, but what struck me most was her strength. Despite everything that’s thrown at her, she doesn’t lose herself completely. Watching her claw her way back to empowerment was such a powerful narrative. For me, Connie represents the idea that strength doesn’t always mean never breaking – it means knowing how to rebuild.”
How can this film raise awareness about toxic relationships?
“Manipulation in relationships can be incredibly harmful because it’s often subtle at first. It creeps in through small compromises, gaslighting and emotional control. Unfortunately, many people don’t realise they’re in toxic dynamics until the damage has been done. That’s why films like ‘Sal Azul’ are important – they shine a light on these difficult issues and encourage conversations around mental and emotional health.”
What was it like filming in Mexico?
“Filming in Mexico was such an incredible experience. It was my first time working there. The location became an extension of the film’s emotional landscape, and the isolation of filming in a place where I didn’t speak the language mirrored what Connie was going through. It helped me tap into her experience and bring that authenticity to the screen. Also, working with the local cast and crew was fantastic. They were so welcoming, and while there was a language barrier at times, the shared passion for the project made communication much easier. The challenges we faced were part of what made the experience so unique and rewarding. It was fun, emotional and intense – all the things you hope for when you work on a project like this.”
What’s the target audience for ‘Sal Azul’?
“’Sal Azul’ is a film for anyone who has faced challenges in relationships or who has struggled to find their voice. It’s emotionally intense, but ultimately hopeful. I’d recommend it to people who enjoy character-driven stories with real emotional depth.”
‘Sal Azul’ is newly released on Amazon Prime Worldwide and Tubi USA
