Texas Chainsaw Massacre is LOOSLY based on Ed Gein. The face mask is really all that its based on, nothing else. So was Silence Of The Lambs (the cannibalism and the nature of Hannibal) and Psycho (Geins weird attachment to his mother -like in Psycho) So no, TCM isnt true...its loosly based on a true story of Gein. The actual events didnt really happen like they did in the film.
