Theater directors hold auditions to select the acting cast members. They collaborate with the technical crew, which may consist of lighting, sound, set and costume designers. Working with producers on large productions, there may be other supporting staff such as artistic directors and music directors to collaborate on extensive production designs.
The director blocks the play by adapting the actor movements to workable floor plans on the set. Leading rehearsals, he or she collaborates creatively with the actors and technical crew to make the blocking natural, changing it when necessary and allowing inspiration.
Actors draw out character motivations and relationships under the watchful eye of the director, who strives to develop these expressions over the performance's required transitions. Directors finish their work when they determine the final pacing of the play reverberates with the life of an artistic vision that is satisfying and complete.
