"Many plays - certainly mine - are like blank checks. The actors and directors put their own signatures on them"

In this quote, playwright Thornton Wilder compares his plays to blank checks. Just as a blank check can be completed with any quantity and signed by anyone, Wilder's plays can be analyzed and brought to life by various stars and directors. He acknowledges that while he may have composed the words and produced the characters, it is eventually the stars and directors who provide their special signatures. This highlights the collaborative nature of theater, where each person involved brings their own creativity and viewpoint to the production. Wilder's plays are open to unlimited possibilities, much like a blank check waiting to be filled.
