Getting the best performance from your actors is crucial for your movie. this is mine Top 10 tips for working with actors on film. 
1. The casting is really good. Make sure you find the best actors of your caliber.
2. Rehearse scene by scene with the actors
For a 10-page script, two sessions are allowed, each half day or full day.
3. Make script dialogue better through rehearsals. Dialogue and performance can be significantly improved through improvisation.
3. On set, watch the actors in action like a hawk on Video Village. One by one, look for anything you want to change in their performance.
4 It’s important for actors to talk at a conversational volume. There’s nothing worse than being an actor.
There will be beats in the scene where the actors need to raise their voices. Such as arguing or delivering a speech to an audience. Pace the scene and talk at a conversational volume. (mics are great now)
6 Watch out for overacting. This is a killer on screen.
7. Watch for flashers in close-ups.
Actors who blink in close-ups always lose the power of the screen, and many inexperienced actors do this. A close-up will illustrate this in detail. It’s worth paying attention to and making sure your actors don’t do this.
8. Keep Directions Simple When Directing Actors -Short sentences with one or simple direction are more effective than articles with multiple conflicting directions.
9 Move away from results-oriented orientation.
Use verbs when directing. Avoid telling actors to “be angrier”
If you want to make the actor angrier, ask the actor to “intimidate or scold”
Asking an actor to be angrier is a state of affairs, less effective than the verb “to intimidate”
In the latter, the actor is doing rather than imitating. That’s much better.
10 When editing the video, look closely at the details of the sprint.
Watch all the footage and mark each actor’s best moment in each take. Taking the time to do this will greatly improve your actor’s performance in the finished film because you will select your actor’s best moments.
The reality is that directors shoot 20 to 30 times as many shots as the final shot of the movie. this is what is called Shooting ratio.
Therefore, it is essential to watch your footage carefully. Find the best performances in your footage like you’re panning for gold.
Only through experience can a director become good at directing actors. On set, working with actors always helps you direct them better.
In a movie, it’s a lot different than directing actors in a play. People only care about the scene and what happens during filming, from action to editing. Directors can take two or more takes until they get the effect they want.
Pay attention to these ten tips and add them to your toolbox. As a director, your job is to make good or great actors stand out.
