The 'Texas Chainsaw Massacre' has roots in true events. The movie took elements from the real - life actions of Ed Gein. Gein's abnormal behavior and his heinous crimes provided the basic framework for the horror in the movie. However, the movie is a fictionalized and exaggerated version of those events for the sake of creating a terrifying horror story.
Yes, 'Texas Chainsaw Massacre' was inspired by real - life events. It was loosely based on the crimes of serial killer Ed Gein. Gein had a very disturbing and grotesque modus operandi which included grave robbing, making items from human body parts, etc. His actions were so extreme that they became the inspiration for many horror movies, including 'Texas Chainsaw Massacre'.
Well, 'Texas Chainsaw Massacre' is sort of based on a true story. There was a serial killer named Ed Gein who did some really messed - up things like taking body parts from corpses. The movie makers took this really dark and twisted real - life situation and turned it into a horror classic. But don't think that everything in the movie actually happened exactly as shown. It's a blend of fact and a whole lot of fictional horror - making.
