Topic: His Name was Jason documentary - I have a question about it

I have most of the Deluxe Edition DVDs for all 7 of the Friday the 13th movies and still need to get the Deluxe Edition DVD for Friday the 13th Part 8.

Each dvd have their own inteviews with the cast and directors but I have a concern about the His Name was Jason documentary DVD.

Is there anything in the His Name was Jason documentary DVD where there's some stuff that's not in the individual behind the scenes stuff for   the Deluxe Edition DVDs for Friday the 13th Parts 1 through 8?
