What do lead actors do?
Exploring the vital role of leading performers in film, television, and theatre

The Core Responsibilities of a Lead Actor
A lead actor, often referred to as the “star” of a production, carries the story’s weight on their shoulders. They are typically the character the narrative revolves around and whose perspective shapes the audience’s experience. Their responsibilities begin far before the camera starts rolling or the curtain rises and continue well beyond.
One of the most critical responsibilities is character development. A lead actor must deeply understand the psyche of their character—what drives them, their fears, desires, and internal conflicts. This process involves script analysis, extensive rehearsals, and often discussions with directors and writers.
“Acting is not about being someone different. It’s finding the similarity in what is apparently different, then finding myself in there,” said Meryl Streep, one of Hollywood’s most respected lead actors. This quote highlights how the actor must blend their personality with the character to create authenticity.
Additionally, lead actors are often involved in promotional activities, script consultations, and even in shaping scenes on set. Their input is highly valued due to their central role in the production.
Bringing the Character to Life
Lead actors don’t just memorize lines—they breathe life into them. Through subtle gestures, vocal intonation, facial expressions, and body language, they make a fictional character believable and compelling.
Consider Daniel Day-Lewis, known for his method acting. In Lincoln (2012), Day-Lewis famously stayed in character for months, using Abraham Lincoln’s voice and mannerisms both on and off camera. This level of commitment demonstrates how far lead actors go to bring authenticity to their role.
“Being a lead means you must embody the emotional truth of the story,” says Viola Davis, star of Fences and The Woman King. “You are the heartbeat of the narrative. If you’re not feeling it, neither is the audience.”
The best lead actors also develop distinct chemistry with supporting cast members. Their performances serve as emotional anchors, allowing others to shine while still commanding attention.
Collaborating with Directors and Cast
Lead actors work closely with directors to ensure the story’s vision is achieved. This collaboration involves understanding the director’s concept, adapting performance to match the tone, and sometimes even improvising to improve a scene.
Robert De Niro, speaking about working with director Martin Scorsese, once said, “There’s a shorthand between us. I know what he wants, and he knows what I can do.” This rapport between director and actor is often cultivated over multiple projects and is crucial to the success of many films.
Lead actors also serve as leaders on set. Their behavior influences the tone of the production, often setting professional standards for punctuality, preparedness, and conduct.
For example, Keanu Reeves is widely respected in the film industry not only for his performances but also for his respectful and humble attitude on set, which boosts morale and productivity.
Rehearsal and Script Mastery
Before filming or performing live, lead actors go through intensive rehearsal processes. They must memorize extensive lines, understand scene blocking, and emotionally prepare for high-stakes moments.
In theatre, rehearsal can span weeks. On Broadway, a lead actor might perform eight shows a week, each requiring the same level of energy and precision. Hugh Jackman, who starred in The Music Man, once mentioned the physical and mental rigor: “You train like an athlete, and you have to love every minute of it.”
In film and television, rehearsals are often shorter, but the pressure to deliver is just as high. Lead actors must often hit emotional peaks multiple times across takes, requiring emotional endurance.
Public Persona and Media Engagement
A significant portion of a lead actor’s responsibilities lies off-camera. They are often the face of the marketing campaign, appearing in interviews, press junkets, and fan events.
Zendaya, lead in Euphoria and numerous feature films, is a prime example. Her grace and professionalism during media tours have helped shape her public image, making her an ambassador not only for the project but for the studio.
Social media has added a new dimension to this. Leading actors now communicate directly with fans, maintaining an online presence that supports both their career and the film’s success.
“A huge part of this job is letting people see you, even when you’re exhausted,” said Tom Holland during the Spider-Man: No Way Home press run. “You’re representing hundreds of people’s work.”
Handling Criticism and Pressure
Lead actors face immense pressure. Their performances are scrutinized by critics, fans, and peers alike. When a project fails, the lead actor often shoulders the brunt of the blame—fairly or unfairly.
Johnny Depp, reflecting on his career highs and lows, remarked, “It’s not just acting. It’s carrying people’s expectations, emotions, and money.” The stakes are high, especially in blockbuster films or award-season contenders.
Dealing with criticism requires resilience. Many actors consult coaches, therapists, or mentors to stay grounded.
Moreover, lead actors must maintain their skills over time. This involves constant learning, whether through workshops, new techniques, or experimenting with diverse roles. Cate Blanchett’s transition from historical dramas to modern thrillers shows her range and willingness to adapt.
Choosing the Right Roles
One of the strategic duties of a lead actor is choosing roles wisely. These decisions can make or break careers. A single transformative role can propel someone to stardom, while a poor choice can lead to setbacks.
Consider Matthew McConaughey, who transitioned from romantic comedies to intense dramas like Dallas Buyers Club. This career shift, known as the “McConaissance,” earned him critical acclaim and an Oscar.
Actors work with agents and managers to select roles that align with their goals and expand their brand. They also consider the script quality, the director’s reputation, and the project’s potential reach.
As McConaughey said, “The script is the blueprint, but I look at the architect—who’s directing, who’s building it with me.”
Mentoring and Industry Influence
Seasoned lead actors often take on mentoring roles within the industry. They guide newcomers, advocate for social causes, and even start their own production companies.
Reese Witherspoon, a successful lead actress, founded Hello Sunshine to promote female-led stories. Her work behind the scenes reflects how lead actors can leverage their status to influence the industry’s future.
Similarly, Denzel Washington has mentored numerous young actors. Michael B. Jordan once said, “Denzel gave me advice that stuck with me—about owning the moment and bringing truth to every role.”
These efforts contribute to the evolution of the craft and the broader cultural conversation.
The Emotional Toll of Leading Roles
Performing emotionally intense roles can affect an actor’s mental well-being. Lead actors often carry the heaviest emotional arcs, from loss and trauma to triumph and redemption.
Heath Ledger’s tragic death after playing the Joker in The Dark Knight prompted discussions about the mental health risks of deeply immersive roles. Though his performance was groundbreaking, it also revealed the dark side of method acting.
Many actors now work with psychologists and mental health professionals to process these experiences. It’s an essential step in maintaining longevity in the profession.
As Emma Stone shared after filming La La Land, “You pour yourself into a role so fully that it feels like a breakup when it ends.”
Conclusion: More Than Just a Star
Being a lead actor is about far more than fame or screen time. It’s a demanding role that requires emotional intelligence, technical skill, leadership, and resilience. From shaping the narrative arc to representing the film in the media, lead actors are central to a production’s success.
They carry the weight of storytelling on their shoulders, often becoming cultural icons in the process. But behind the glamour lies a profession of discipline, vulnerability, and relentless pursuit of truth.
As Tom Hanks once said, “The responsibility of a lead actor is not to steal the show—it’s to tell the story.”
In telling those stories, lead actors inspire, challenge, and transform audiences around the world.
