Q. My statue is static. Only talks to other characters. How do I take him on the journey and change him? And how do I give him character?
Well, the journey bit can still be literal. The statue may be taken on the journey by other archetypes. This is common in fantasy where the goal is to turn somebody back from statue to human, but can only be done after meeting some mystical wizard in a far off place etc.
Or the statue may change as a result of other archetypes going on a journey. So as they progress and change, you can arc your statue accordingly, demonstrated through his thinking, demonstrated through his words.
As for giving the statue character, the same applies as to all archetypes. Give him outer and inner challenges, limitations which he will have to let go off etc.
The Hero's Journey and Transformation through a New World/State is the template upon which the vast majority of successful stories and Hollywood blockbusters are based upon. Learn about this at http://www.clickok.co.uk/index4.html
