As in any theatre production, the first step is for you to be given your script.
Place the script in a binder because it should be a part of your daily reading and will be. Purchase a highlighter pen and highlight all of your parts. Highlighting the script will assist you for what is known as THE READING. The Reading is the first step in getting to hear the other actors voices , reading styles and character analysis in the play. Place your name on your script and keep your script clean. If you have the resources, make a second copy.
I was instructed by the great Whitman B. Mayo (1930-2001), who as you know played Grady from NBC's Sandford and Son, to read my script every day. Try to extract a new nuance about your character daily and don’t wait to develop your character during rehearsals. The act of repetition will give you that edge to FEEL the lines, learn the before and after lines (lines preceding your lines and lines that come after your lines). Remember improvising may be necessary if an actor forgets their lines. The repeat process gives you incentive to get in touch with the character’s feelings and do what would come natural, thus giving your performance an appearance of reality.
Always remember, THEATRE IS ART THAT IS THE IMITATION OF LIFE!
