Will AI Replace Film Extras? Why Real People Still Make the Difference on Set

Artificial intelligence is changing the way films and television programmes are made, and hardly a week goes by without another headline asking whether AI will eventually replace actors, extras or entire crowd scenes. It is an interesting debate, but perhaps not the question producers should really be asking. If you have ever watched a film and become completely immersed in the story, chances are it was not because of the technology behind it but because the people on screen made you believe every moment. As AI continues to develop, that simple fact may become more important than ever.

Why This Conversation Is Happening Now

Open any industry publication or spend five minutes scrolling through social media, and you will almost certainly come across a discussion about artificial intelligence in filmmaking, whether that is digital extras, AI-generated crowd scenes or performers being scanned for future productions. If you work in film, television or production, these discussions are impossible to ignore, and if you simply enjoy watching a good film, they are equally fascinating because they make you wonder what the future might actually look like.

The truth, however, is rarely as dramatic as the headlines suggest. Artificial intelligence is undoubtedly changing parts of the industry, just as computer-generated imagery changed filmmaking a generation ago, and it can help extend a crowd, create environments that would once have been impossible to build and speed up certain parts of post-production. There is no denying that the technology is impressive, and it will almost certainly become a bigger part of the filmmaking process in the years ahead.

What is often missing from the conversation, though, is why audiences connect with films in the first place, because most of us have never left the cinema talking about how convincing the digital crowd looked in the background of a scene. We leave talking about the story, the atmosphere and those moments that somehow felt real enough to pull us into another world for a couple of hours. That is where the conversation becomes genuinely interesting, because while technology continues to evolve at an incredible pace, the thing audiences continue to value most has remained remarkably consistent: people connect with people.

Why Great Crowd Scenes Never Feel Like Crowds

Think back to a film or television series that completely drew you in, perhaps a gripping crime drama set in central London, a period piece with bustling market squares, or a blockbuster where thousands of people appeared to be going about their day, and chances are you were so invested in the story that you barely noticed the people in the background. That is exactly the point, when extras are doing their job well, you should not notice them individually but instead experience them as part of the world the director is trying to create, giving a scene movement, atmosphere and credibility without ever pulling your attention away from the main action.

Imagine watching your favourite television drama where every café has only two customers, every shopping street looks half empty, and every football stadium is missing its supporters. The dialogue might be brilliant and the lead actors outstanding, but something would feel fundamentally wrong, and even if you could not immediately explain why, the illusion would begin to disappear. That is because our brains are very good at spotting authenticity, since we spend our entire lives surrounded by people and instinctively understand how crowds behave, noticing the parent trying to keep hold of an excited child, the couple laughing as they cross the road or the commuter glancing at their watch. None of these moments is important on its own, but together they create the texture of everyday life, and it is those tiny details that make a film feel believable. They are also, ironically, some of the hardest things to recreate artificially.

Can Technology Really Recreate Human Behaviour?

Modern technology is capable of creating remarkably convincing crowds, extending stadiums and filling city streets with computer-generated people, and for the right scene, it can save time, solve practical challenges and achieve things that would have been impossible only a few years ago. The real question is whether audiences experience those scenes in quite the same way, and the answer often comes down to something very difficult to programme.

Human behaviour is wonderfully inconsistent. Nobody walks at exactly the same speed; people pause unexpectedly, look in different directions, adjust their coat when the wind picks up or smile at something just outside the camera frame, and even when a group of extras has been carefully briefed, every individual brings something slightly different to the scene simply because they are human. Those small imperfections are often what make everything feel perfect, since you can usually sense when something feels too uniform even if you cannot explain why, and a crowd that moves with mechanical precision or reacts in exactly the same way can leave a scene feeling polished but strangely lifeless.

That is why so many directors continue to value real people on set, because they are not simply filling space in the background but helping to create an environment that feels lived in, spontaneous and believable in a way that even the most sophisticated technology struggles to match.

Authenticity Is Becoming More Valuable, Not Less

There is something slightly ironic happening at the moment, because as artificial intelligence becomes more sophisticated, audiences seem to be appreciating authenticity even more. You only have to look at social media to see it, since some of the most popular behind the scenes videos are not spectacular action sequences or expensive special effects, but clips showing what happens between takes, with extras chatting while they wait for cameras to roll, crew members resetting a busy street scene, or hundreds of people returning to their starting positions so a director can capture exactly the same moment again.

People watch because it reminds them that films are still made by people, and there is something genuinely refreshing about seeing the reality rather than the polished final edit, since it reveals that behind every memorable scene is an enormous team of individuals, many of whom most viewers will never know by name, yet every one of whom contributes to what eventually appears on screen.

Why Professional Extras Still Matter on Every Set

For production companies, casting directors and agencies, the current conversation around AI is not simply about keeping up with technology but about understanding where technology genuinely helps and where real people continue to make the biggest difference. There will undoubtedly be scenes where digital effects are the right solution, particularly when budgets, safety or scale make traditional filming difficult, and extending a stadium crowd or creating a city skyline full of people may be quicker and more practical using visual effects, and few would argue against using technology where it genuinely enhances the final result.

What remains much harder to reproduce is the unpredictable nature of human behaviour on set. An experienced extra understands far more than simply where to stand, since they understand continuity, know how to follow direction, appreciate the pace of a working film set and instinctively become part of the environment without distracting from the action, helping to create the atmosphere that allows audiences to believe they are watching a real place rather than a carefully constructed scene. That experience comes from people, not programmes, and it is also why professional casting agencies continue to play an important role, since productions need more than numbers and instead need reliable people who understand what is expected of them, arrive prepared and contribute positively throughout what can often be a very long day on set.

The Bigger Picture

It is easy to become distracted by headlines predicting that artificial intelligence will transform every aspect of filmmaking, because dramatic headlines naturally attract attention, yet the reality is usually far more balanced. Throughout the history of cinema, every major technological advance has raised similar questions, and when computer generated imagery became more common, many people assumed practical effects would disappear, while digital cameras were predicted by some to mark the end of cinematic craftsmanship. Instead, filmmakers found new ways to combine technology with creativity, and artificial intelligence is likely to follow exactly the same path, becoming another valuable tool and another way of solving problems rather than a replacement for the human element that makes great productions work.

The productions that stand out in years to come are unlikely to be those that relied solely on technology, but rather the ones that used it intelligently while never losing sight of what audiences care about most, which is stories, emotion and connection, and ultimately people telling stories about people.

 

If you are planning a film, television programme, commercial or promotional campaign, think beyond the technology, because the most memorable productions are rarely remembered for the software that helped create them but for how they made audiences feel, and that authenticity still begins with real people on set.

Frequently Asked Questions

Will AI completely replace film extras? While AI can create or extend digital crowds, most productions still rely on real extras to bring authenticity, natural reactions and believable atmosphere to a scene, and many directors feel that no technology currently available fully replicates what a well-briefed group of people can achieve on set.

Why are productions still using real extras? Real people create the subtle interactions, movement and emotion that help audiences believe what they are watching, and those small details remain difficult to recreate convincingly using technology alone, particularly in scenes that require natural and spontaneous human behaviour.

Can AI be useful in film production? Yes, and AI is becoming another valuable production tool that can support visual effects, crowd enhancement and certain post-production tasks, with most filmmakers viewing it as something that complements human creativity rather than replaces it.

Why is there so much discussion about AI and performers? Much of the debate centres around consent, fair pay and how digital likenesses are used, with performers and production companies working to establish clear and ethical standards for how artificial intelligence is used within the industry going forward.

Why should productions use a professional casting agency? Professional casting agencies provide experienced, reliable extras who understand how a film set operates, helping productions run smoothly and on schedule while also creating the authentic and believable scenes that audiences respond to.

What makes a great extra? A great extra is reliable, professional, takes direction well and understands that even the smallest background role contributes to the success of the finished production, which is why experience and the right attitude matter just as much as simply being available on the day.
