this documentary is contained on the bonus disc of the original "Texas Chainsaw Massacre ultimate edition released in 2006.the documentary was originally produced in 2000,though i think it has some material added since then.either way,it's a pretty good documentary,with revealing interviews with many of the original cast and crew.it reveals a few surprising things about the production itself,but also about the aftermath.i was surprised at how much money the movie made.keep in mind this is 1974.as far as documentaries go,this is one of the better ones.many documentaries merely repeat things everybody already knows,but this one has is refreshing,and actually shows new insight into the movie.it's also highly entertaining.at least i think so.i also like that it gives you updates on where the cast and crew are now.all in all,a very good documentary,well worth watching.for me "Texas Chainsaw Massacre":The Shocking Truth" is an 8/10
