Wisher based his performance as Davros on the philosopher Bertrand Russell. Prabhu takes the credit by pretending to be that anonymous well wisher. It stars William Wisher Jr. and Margaret Umbel. The story introduces the Daleks' creator Davros (Michael Wisher), who had a unique visual design. Written by William Wisher Jr. and himself, Schwarzenegger and Linda Hamilton reprise their roles. Cameron gave Wisher scenes involving Sarah Connor and the police department to write. Each chapter focuses on a different wisher whose wish Renya must grant. This is the final appearance by Michael Wisher in "Doctor Who". She was assisted by Grace Wisher, an African American girl at just 13 years old. Wisher could even eat while wearing the mask. Frakes and Wisher would later write the US-released novelization of the movie.
