Passion 2 Create!
"Naturally" speaking and physically behaving as the character you're playing in its true form needs to be prepped before the first day on the set. You are combing through the script and seeing what your character does/reacts/says in conjunction with the other characters.
Suggestion: Most characters, particularly the main characters have backstory already written about them before the script is written. Speak to the Writer, Director, Producer...to see how to get a hold of these notes on your character. This will give you clear insight on bringing your character alive in his or her true form. I will do this with my actors.
Are you all, as characters, best friends? Lovers? Secret rivals? Known rivals?...etc.
What happened in the past with your character and the characters in your same story prior to the beginning of the story. Did your love run away? Did your child change their gender, to your dismay? Did you leave your job, which led you to no longer be able to afford your house and at the beginning of the story, you and your family has to move? Are they all mad at you? Are they all in agreement with you? There are so many things to consider in it all.
How do you as an actor make this a vivid reality on the screen that will stay in many of the audiences' minds for many years? Think of "Rain Man". Think of "Forrest Gump". Some other notable characters come to mind right now, don't they? Yes. You got it! They were unique and YOU need to be, AS WELL!!! Communicate with the Director on what is revealed to you and listen to the Director’s wishes and notes. The Director with his/her skill and production wisdom was chosen for this production for a reason.
Theatrical (Stage) acting is quite different than acting in front of the camera.
On the stage, you project your voice for every single person in the audience...all the way to the back row...to hear your every word.
On the camera, your acting expressions and words spoken can be as low as a literal whisper if your character calls for such but it is heard crystal clear on the screen.
Your expressions appear natural on the screen and are exaggerated on the stage.
With your lines memorized and ready to go and act them out, come on the set ready. Have fun with it and make it a wonderful experience. Be ready for your call times and your cues. Listen to what works and does not work from the Director’s notes to you. Be open for the varying possibilities. Sometimes you can wow those on set with your revelations and there are also times where the Creative Boss (Director), too, will see things and give you a direction to operate in which will bring about your best performance yet! Be open to the possibilities! It will allow for a better production.
Your skilled acting techniques AND clarity in dialogue spoken by you has to come through clearly for the audiences viewing your talents on the screen. How many song lyrics have we, as listeners, totally mistook and have sang them wrong, throughout the years...because we "heard" something else instead of the true words? This can happen on the camera, too.
If, for some reason, something, for some reason, just happened not to record correctly, let’s say, from an audio standpoint...or it sounds like you’re saying “I’m ready” when you should be saying “spaghetti” that would sound like a really weird thing to a waiter who is in the middle of taking your order. And/or it throws off the whole series of dialogue after this point. :-) Be prepared to come in and re-record this portion of dialogue in the editing room. Make it as fun as possible while still being professional!
