Reuters reports on a Japanese stage play, Sayonara in which a robot caretaker of an ill woman is actually played by a robot (or more accurately by an android, since the machine is made to look human).
Another, print, report is here. The android is named Gemini-F. The director, Oriza Hirata, says that the android is not intended to replace human actors, but that a new category of actors is now emerging, a mixture of human and machine.
