I actually know this guy though I haven't seen him in over 25 years. He's a Hollywood choreographer who coached the dead people in hell for the movie
What Dreams May Come and the zombies in
I Am Legend.
I couldn't make it to the end of the video though I did force my way through the first 8 minutes or so. Co-workers that started watching it found him pretty annoying and it was my wife who came up with the thread title after 5 minutes. I recall him being pretty arrogant and sleazy. The kind of guy who swoops in and tries to seduce women who just broke up with their BF's and are still upset and vulnerable.
