Callbacks & Chemistry Reads

After the first round, you'll have a shortlist per role — the actors who impressed and directed well. The callback is the second, deeper look at those finalists, and it's where the real decision gets made. You go further: more material, harder direction, and — crucially — pairing actors together. That last part, the chemistry read, tests something a solo audition simply cannot reveal: whether two people believe as a couple, a family, or enemies on screen.

What a callback is for

A first audition answers "can this person play the role at all?" A callback answers the harder questions you can only ask of your best options:

• Do they hold up on more material? Give finalists new or longer sides — a great actor deepens with more to play, a shallow one thins out.
• How far can you push them? Direct harder, try bigger swings. You're mapping their full range now, not just confirming competence.
• How do they feel over time? A callback is a longer hang. You start sensing what weeks of collaboration would be like.
• Can the director and actor connect? If a CD ran the first round, the callback is often where the director really engages and tests the working relationship.
• How do they pair with others? The chemistry read — below — which is often the whole reason to hold callbacks.

The chemistry read

Here's the thing individual auditions can't show you: two actors can each be brilliant alone and feel completely dead together. Chemistry — romantic, familial, antagonistic — is a property of the pair, not either person. So for any relationship the story leans on, you bring finalists in together and have them play a scene, watching not each performance but the space between them.

You're looking for the invisible current: do they listen and react to each other, or just deliver lines near one another? Is the tension real? Would an audience believe this relationship? Try different pairings from your shortlists — sometimes your two favorite solo actors have no spark, while an unexpected combination lights up. When it clicks, you feel it in the room. That "felt" pairing is often more important than which individual gave the technically best audition.

Running a good callback

• Prepare fresh material. New or extended sides show you more and reward actors who keep discovering.
• Mix and match pairings. For key relationships, read your finalists against different partners to find the best combination.
• Get the deciders in the room. The director (and key producers) should be present — this is where the choice crystallizes.
• Record the pairings, not just the people. When you review later, you're comparing combinations, so capture them on tape.
• Keep respecting their time and effort. A callback is a bigger ask; treat finalists well and be honest about timeline and next steps.

Trust what you feel — then verify it

Chemistry is partly a gut read, and that's okay — your instinct in the room is real data. But verify it on the recording, because the energy of a live room can mislead. Watch the chemistry read back: does the spark survive the screen? The camera is where the audience will meet these actors, so the tape, not the room, is the final word. When your gut and the footage agree, you've found your pairing.

You've tested your finalists solo and together, and you can feel who's right. Now comes the judgment call itself: how to weigh everything and cast the right actor — not just the best audition. That's next.
