The reason nobody knows his name is because on most of those movies, he worked as either a First AD or on the second unit. The scariest thing to me about this is the fact that he was a first AD on so many movies, but the only thing he's actually directed is Highlander: Endgame.
For those who don't know, many times, a first AD doesn't get to direct AT ALL on any given movie. They mainly deal with the production schedule, and with corralling the actors. I have a close friend who is a first AD, and being one doesn't mean that you necessarily have any directing abilities at all.
I understand that this guy has done some second unit directing, which sounds a little more promising than if he had only been a first AD. But overall..this sounds scary. :\
