I have tons of respect for Mark Houghton, and this interview is very insightful:

Also, here is the trailer for his documentary, I Am The White Tiger:
Is it my imagination, or has Mark Houghton developed a bit of a Cantonese accent?
Having seen the documentary “I Am The White Tiger,” I rate it as excellent. Mark Houghton’s story is an amazing one; just seeing him in his movie appearances is not enough to truly appreciate his story. His challenges, his near-death experience(s). What impressed me the most was his true embodiment of Wude; in particular, in honoring his sifu, Master Lau Kar-Leung and his family. To tell the honest truth, I found myself getting emotional watching it, which is something I never would have expected in a million years.
Mark Houghton’s story is a truly inspiring one.
