"I want this to be a journey of discovery for new film-makers. I won't necessarily be saying 'do this'. I'll more likely point them in a direction or suggest an angle and allow them to make their own discoveries."
Mr Callen has more than 40 years' experience as a professional actor, director and writer in theatre, radio, film and television in New Zealand and overseas. He has performed in or directed more than 100 stage productions and two dozen television series, and worked as a lecturer at Toi Whakaari, Unitec drama school and the University of Auckland.
Mr Callen's most recent acting role has been as a dwarf in the core cast of The Hobbit. He is returning to New Zealand from Germany this week especially for the workshop, having been attending the Hobbitcon fan convention in Bonn.
He said being involved in events such as the free workshop and CreationFest was important for fostering the creative arts in New Zealand, as it was about contributing to the country's culture that was then portrayed onscreen to the world.
"I'm in love with the entire industry and every aspect of performing and directing, even writing, and I love working with acting students. We need more New Zealand stories as we are constantly evolving and developing."
