The prequel to The Texas Chainsaw Massacre will explore Leatherface's family and reveal how they became serial killers, producer Brad Fuller has revealed.

"It won't have any of the young actors from the first (like Jessica Biel), this is a prequel," Fuller told Zap2it. "But there will be a group of teen and young adults in their 20s who make an unfortunate decision to end up in this town."

Fuller explained that the story of the murderous family will be told in full.

He added, "We hope that you'd eventually be able to watch the two movies together and it will explain a lot of questions that were unanswered."
