AN AFTERNOON WITH... BARBARA GUERRERO

You've worked on massive projects like Eternals and Foundation . How do you design a workflow to ensure the look of hundreds of extras is consistent and, above all, withstands marathon shooting days without the set team collapsing?

- Barbara: The key is understanding that in projects like this, makeup ceases to be solely artistic and becomes pure logistics as well. First, there's a very solid pre-production plan: tests, group classifications, exhaustive photographic documentation, and, above all, a clear system that the entire team can replicate. When you're working with hundreds of extras, you can't rely on memory; you need structure.

Next, delegate effectively. Develop team leaders who understand the overall concept and communicate it clearly. And something crucial: create a calm environment. If the team feels organized and confident, the set won't collapse. In reality, leading a large department is a constant balancing act between creativity and organization.

The Hierarchy on the International Set: These productions often involve crews from different countries. What methodological benefits have you gained from working under the standards of the major American studios that you've been able to incorporate into your shoots in Spain?

- Barbara: I've learned rigor. A lot of rigor. Listening to the needs of all departments, understanding that there's a much higher hierarchy, and putting yourself in the right place on each project. Order is fundamental in these projects.

In large international productions, everything is documented, everything has a protocol, and everyone knows their responsibilities. That provides enormous peace of mind because it allows you to concentrate on the creative side without improvising from a chaotic situation. I've also learned the importance of respect between departments. Makeup doesn't work in isolation: wardrobe, photography, directing... we're all cogs in the same machine. That collaborative mindset is something I always try to apply, even in national productions.

From "Beauty" to "Gore": Your training is incredibly broad, encompassing all branches of makeup and special effects. How has your perspective on a face changed after learning to "destroy" it with special effects? Does this knowledge help you when retouching conventional beauty makeup?

- Barbara: Absolutely. When you learn special effects, you understand anatomy from the inside out. You understand how skin behaves, how it ages, how the harmony of a face is disrupted. And interestingly, that makes you more subtle when you work in beauty.

FX taught me that less is more. That texture matters more than color. And that well-integrated makeup is the kind that goes unnoticed, the kind that breathes with the actor.

The Weather Factor: You've filmed in the extreme conditions of the Canary Islands and the humidity of Galicia . What's your technical strategy for combating makeup oxidation and unwanted shine when the weather is your biggest enemy?

- Barbara: With planning and a lot of trial and error. In the Canary Islands, the sun is relentless, and in Galicia, the humidity is a constant challenge. The important thing is to know the products well, work in very thin layers, and always think about continuity. But beyond the technical aspects, it's about anticipating: talking to the photographer, predicting changes in light, and having backup plans ready. 

The weather isn't the enemy, it's just another department you have to negotiate with.

In an environment as hierarchical and stressful as a film set, how do you manage your team's motivation so that the artistic quality doesn't drop despite fatigue?

- Barbara: I've learned that the leader sets the tone. Listening and staying calm when things get complicated helps me make better decisions. If I get upset, the team can be affected. If I remain calm, even in tense situations, the team responds better. I try to make my department a safe space within the chaos that a film shoot can be. Listening closely to the team, recognizing good work, and protecting them when needed. Giving them the recognition they deserve and motivating and supporting them during difficult times. The artistic quality doesn't suffer when the team feels valued .

What is the key to "translating" an abstract idea from a script into a technical makeup solution that is both economically viable and visually impactful?

- Barbara: It all starts with listening. Often, an abstract idea just needs to be translated into something concrete and viable. I ask questions, request references, and propose realistic solutions in terms of time and budget.

The makeup has to be exciting, but it also has to work within the machinery of filming.

The Technological Leap: You started in the industry before the 4K and 8K explosion. What application techniques from your student days have you had to "unlearn" or radically transform to ensure that makeup remains invisible under today's ultra-sharp lenses?

- Barbara: We've had to unlearn a lot of things. Before, you could "cover up" more; now the camera sees everything. I've had to work more with real skin, less product, more preparation. Thick textures no longer work. Today's makeup is more transparent, more respectful of the actor's skin. In a way, technology has forced us to return to the essence .

Organization is a Tool: How important do you consider "facecharts" and digital documentation in your pre-production processes?

- Barbara: That part is crucial! Creativity without organization is lost in these cases. Face charts and digital documentation aren't bureaucracy; they're a record. They allow for continuity, consistency, time savings, and practicality. In international productions, it's unthinkable not to document everything. In long-form fiction, even more so. It gives me peace of mind knowing that any team member can consult a clear reference at any time.

Advice for the Next Generation: Many young makeup artists get frustrated if they aren't "Main Talent Artists" right away. Seeing your success as a coordinator and in large-scale departments, how much value do you place on learning the trade from the ground up before making the leap to department head?

- Barbara: Learning from the crowd is a gift. That's where you understand the realities of a film shoot, the dynamics on set, and teamwork. Being a Main Talent Artist is wonderful, but if you haven't gone through the entire process, you're missing out on a part of the craft. It's a long road. It's not a sprint, it's a marathon of endurance and perseverance. Each stage gives you tools that you'll appreciate later when you have to lead.

Letter to Barbara of '99: If you could travel back in time to that year, when a young Barbara began to dream of paintbrushes and film shoots, and you could give her advice for the moments when the road got tough, what would you tell her so that she would never lose hope?

- Barbara: I would tell her not to rush things. That there will be tough times, moments of doubt and exhaustion, times when she'll want to throw in the towel, but that every shoot will teach her something. That she should nurture her curiosity and never lose her ability to observe. That she should value the journey, the path itself! And above all, that she should trust her intuition. Because in the end, beyond the techniques and the big projects, what sustains you is the love for the craft; it's a long career that requires a lot of physical effort and the ability to manage the "not-so-good" moments without falling into despair.

For me, the effort has definitely been worthwhile, even while on the path of constant learning and always trying to improve every day.

Talking to Bárbara Guerrero reveals that success in this industry is a marathon, not a sprint, won with talent, but above all with rigor and respect for the team. Her career reminds us that makeup is the art of details, but also of grand scale.

Thank you, Barbara, for sharing your vision and for being a role model of how to lead with professionalism and passion on every set.
