Another important difference is the production process. In theater, actors usually rehearse for weeks or months before performing the entire story continuously on stage. They must memorize long sections of dialogue and maintain their energy throughout the performance. Film actors work differently because movies are often shot out of order. An emotional scene from the end of a movie may be filmed before the beginning scene.
Film actors must therefore maintain continuity in their emotions, appearance, and behavior throughout the production. Voice control is also very important in theater acting. Stage actors need strong vocal projection so the audience can hear them clearly without the help of microphones in some performances. Film actors usually rely on microphones and advanced sound technology, allowing them to speak more softly and naturally.
