To answer your question, I closed your post because the question was answered, there is no leatherface, never was, the footage you saw was not real, it was a mockumentary of sorts to enhance the realism in the film.
Also, there are so many threads about TCM, I close new ones that don't immediately raise new points about the film.
I am now going to close this thread as well, I hope my answer was satisfying for you, if you have anymore questions, please PM me, don't start anymore threads like this.
If you wish to discuss the TCM remake, search the forum for the thread that is dedicated about it, it shouldn't be too hard to find.
Closing.
