Watch on HDtoday. Vocation is a documentary on artists who knew from a very early age they wanted to be an artist. A decision that for them was instinctual and some may even say it is 'a calling' based on faith and perhaps even fate alone. Artists Andy Jones, Deepa Mehta, Marie Brassard, Christopher Pratt, Brad Peyton and Bif Naked are committed to creating work in theatre, literature, music, film and performance based on an innate desire to succeed while working in the precarious profession of art.
