The documentary's story illuminated some stuff that the narrative film did not show. In reality Mark Shultz had left team foxcatcher before his brother Dan even took a job there. It also didn't really highlight the early success and great opportunities that the Foxcatcher facility provided for USA Olympic caliber wrestlers.
I highly recommend this documentary for anyone who wants to see the real story behind the film Foxcatcher. The Prince of Pennsylvania is available on Netflix. This documentary shows the haunting rise and fall of the man behind the 1990s wrestling champions.
