The Six Factors Casting Directors Use to Assess Risk (And Why You're Probably Focusing on the Wrong Ones)

When I tell actors that casting directors are assessing risk, they usually think I mean "Will this actor forget their lines?" or "Will they turn up on time?"

Those things matter, certainly. But the risk assessment starts much earlier than that.

Every time a casting director puts an actor into an audition, they're making an unspoken promise to the director: "This person can do the job." If that promise proves false, the casting director's reputation suffers. If it proves true repeatedly, their career thrives.

After forty years directing television drama, I've seen this calculation play out thousands of times. Casting directors aren't being arbitrary or difficult when they seem cautious about new actors. They're protecting something essential: their professional credibility.

Understanding what they're actually assessing changes how you approach building your career.

The Six Risk Factors

When a casting director considers any actor for any role, they're unconsciously running through six questions. Not all six factors carry equal weight for every role, but all six are always in play.

1. Can they see you acting on screen?

This is why showreels matter more than anything else you'll ever create. A casting director needs to see you working on camera, delivering a performance, inhabiting a character. Theatre reviews don't answer this question. Headshots don't answer it. Even a drama school graduation doesn't fully answer it.

Screen acting is different from stage acting. The camera reveals details—both positive and negative—that aren't visible from row M of a theatre. Casting directors need to see how you read on camera before they'll risk their reputation putting you in front of a director.

2. Are you physically right for the role?

This isn't about being attractive. It's about whether you could conceivably be the character the script describes. If the role is "SARAH, 40s, Welsh, headteacher," the casting director needs to believe you could be that person when they picture you in the scene.

This is about type, not talent. A brilliant actor in her twenties with a London accent isn't getting seen for that role—not because casting directors doubt she could learn a Welsh accent or play older, but because, for an untried actor, they want someone who IS that person when they walk into the room. You need a body of work proving your range before you'll be considered outside your natural screen type. Until then, casting breakdowns remain highly specific because casting directors are looking for the closest natural fit.

3. Do you have relevant experience?

"Relevant" is the keyword here. If you're being considered for a guest role in a television series, the casting director wants to know: Have you done this before? Do you understand how television production works? Can you handle the pace and technical demands?

Your university's production of Hamlet doesn't answer that question. Your three-line role in an actual television episode does. This is why your first few screen credits are so valuable—they prove you can handle the specific pressures of screen work.

4. Have they worked with you before?

Casting directors remember actors. If they've cast you once and you were professional, prepared, and good, you've dramatically reduced their risk for next time. They know what they're getting.

This is why building relationships with individual casting directors matters more than most actors realise. It's not about being friends. It's about being someone whose work they know and trust.

5. Can you deliver in the audition room?

Screen auditions are their own specific skill. You're performing in a small room, often reading with a casting assistant rather than another actor, usually with minimal preparation time. Some talented actors don’t deliver under these conditions. Others thrive.

The audition itself is a risk assessment. Can you take direction? Can you make adjustments quickly? Do you understand what the scene needs? This is why audition technique matters as much as acting technique.

6. Can they see you in the role?

This final factor is the most subjective and the most important. It's the mysterious alchemy of casting. Sometimes an actor ticks every box on paper, but the casting director simply can't picture them as the character. Other times, an actor lacks some credentials, but something about them feels exactly right.

You can't control this factor entirely, but you can influence it by doing everything else well. The more clearly a casting director can see you as a professional, capable actor, the easier it becomes for them to imagine you as the specific character.

The Risk Reduction Strategy Most Actors Get Wrong

Most new actors focus on the wrong factors in the wrong order.

They pursue agents before they have showreels. They worry about their appearance rather than understanding their type. They take any acting work rather than specifically building screen credits. They network randomly rather than systematically building relationships with casting directors who actually cast the kinds of roles they're suited for.

This isn't a lack of intelligence. It's a lack of system knowledge. Nobody teaches actors how casting directors think or what sequence of development actually works.

The factors I've outlined aren't secrets. They're straightforward professional criteria. But most actors either don't know them or don't understand how to address them systematically.

Why This Matters Now

Understanding these six factors does two things.

First, it depersonalises what’s seen as rejection. If you're not getting auditions, it's probably not because you're untalented or because the industry is unfair. It's because you haven't yet addressed one or more of these specific, fixable risk factors.

Second, it gives you a roadmap. Instead of flailing around hoping for a break, you can identify which factors you've addressed and which ones you haven't, then work systematically to build what's missing.

The difference between actors who build sustainable careers and actors who remain frustrated isn't talent. It's understanding what actually needs to be built and tackling it in the right sequence.

Where This Leads

Understanding what casting directors assess is essential, but it's just the foundation. You also need to know how to address each factor systematically, which ones to tackle first, what materials you need to create, and how to position yourself so casting directors can actually find you when they need someone like you.

That systematic approach—addressing each factor in the right sequence, building sustainable career foundations rather than hoping for lucky breaks—is what the 21-Step process provides.
