"Fyre: The Greatest Party That Never Happened" was made by the Fyre Fest people.

Similarly the hilarious tech failure "Riot On!" was made by themselves. The director was a pseudonym.

A bit more on topic but meta it's interesting the US military has sent historians to current engagements since WW2 - https://en.wikipedia.org/wiki/Military_history_detachment
