Nick used to come into the writers' room and complain bitterly over the
lack of quality in the scripts. What I knew about Nick was that he was
bitching because he cared about the material and he went straight to
the writers' room to try and convince them to write stuff that would be
interesting for him. And I remembered him so clearly later when I was
creating Da Vinci's. I knew immediately that he was probably the only
actor at that time in Canada that I felt could have the right look and
the experience. [on working with Nicholas Campbell on Diamonds]
