Suggesting that improvisation is an invaluable technique that can be used in acting classes and in rehearsals for school, amateur, and professional productions, this book presents 900 improvisation ideas for teachers and directors to use. The first section presents ideas for improvisations on character conflicts, including teen/parent conflicts, student/teacher conflicts, co-worker conflicts, doctor/patient conflicts, police conflicts, and brother/sister conflicts. Other sections of the book present ideas on using contrasts, obstacles to solo improvisations, physical positions, lines of dialogue, the environment, and props in improvisation. The final section discusses using improvisations during rehearsals to improve scene design; plan blocking; explore character traits, background, and off-stage action; and acquaint actors with props and costumes.
