 Working title: "Gemini". The studio didnt like it, and so switched  to "Twins". This was changed to "Dead Ringers" after  Ivan Reitman (qv), who had produced two of Cronenbergs early  films, approached Cronenberg about purchasing the rights to use the  title "Twins". Twins was then used for the  Danny DeVito (qv)/Arnold Schwarzenegger (qv) film  _Twins (1988/I)_ (qv).
