This seems like a very obvious step, but it's really important. When you get to the actual filming part you want the actors to be comfortable with their lines and their blocking. Start off by having a script run-through, where you and your actors sit around a table and run through each scene. They'll be getting more comfortable with the words and with you and with each other, which will make the filming part much easier. Really talented actors don't necessarily need much of a rehearsal before shooting and it can be better to not over-rehearse highly emotional scenes so that they will be fresh for the actual shoot, but that only works with seasoned and talented actors, so if you're working with amateur actors, practicing the script before shooting is a good idea. An actor can't give a stunning performance without knowing their script backwards and forwards. You do not want them to suddenly turn up on set the day of the shoot without having learned their lines. This is why rehearsals are so important. This means what is going on in the scene beyond simply the dialogue. It will also tell an actor what his or her character's true intentions are, in the scene and in the movie, which will determine how you direct them. Less is more in acting in a movie. What you want for your actors is a strong presence that shows even when they aren't doing anything. An actor that can draw viewers into the character without doing much. For example: John, our angry protagonist from above, is going to be played differently depending on whether he hates his girlfriend for leaving him, or if he's still in love with her (or both). The cliche of the angry, screaming director is just that, a cliche. As the director you're the one in charge (if you don't have a producer) which means that everyone's going to be looking to you for calm and clear direction. This is why the storyboard and script breakdown are so important. You can refer back to them for each scene and for showing your vision to those who are working for you. Remember that a movie gets made based on the contributions of a lot of different people, even if the director and the actors get most of the credit. It's best not to behave like you're the most important thing on set, when you're dealing with your cast and crew. This is for the actors. If you've explained the subtext to your actors and your vision for the film, there shouldn't be too much of a problem of them doing what they need to do in their scenes, but it is important that you give specific instructions, even ones like "try that line again faster." Take copious notes. On your shot list write down specific camera critical things you are going to want your actors to do. The clearer and more detailed you can be in your feedback and your requests, the easier it will be for the actors and the crew to follow through on your vision. Give negative or detailed feedback to actors in private. You can even do this when other people are around, just as long as only the actor who is receiving the feedback is hearing it. This way no one gets embarrassed or offended. Make sure to give positive feedback. Actors like to know that their work is being appreciated and that they are doing the right thing. Make sure you let them know that, even if it's something as simple as "I really liked what you did in the last scene; let's try that when we're filming the shot." Sometimes, if you have a really good actor, it's best to let them do their own thing without a whole lot of direction. While it may not always go in the direction you had planned, scenes and the movie itself have a possibility to go in a new and fresh direction.
