Film-maker Shirley Horrocks, documents Sir Paul Callaghan's world of atoms and molecules. Sir Paul, who died in 2012, used nuclear magnetic resonance as a choreographer directs a dance. He saw New Zealand as 'a place where talent wants to live' and his desire was to make the mainland predator-free. In Dancing with Atoms, Shirley Horrocks interviews Sir Paul's brother Jim, colleagues, students and friends, chronicling the life of one of New Zealand's greatest scientists. The premiere is at the Embassy Theatre in Wellington this Sunday at 3:30pm.
