Dennis Rader became infamous as the BTK Killer. He killed 10 people in Wichita and Park City, Kansas, between 1974 and 1991. The BTK Killer taunted the police by sending them letters detailing his crimes in gruesome details. Rader was eventually arrested for his crimes in 2005 after he resumed sending letters to the police a year earlier. “Mindhunter” fans are well aware how important the BTK Killer was to “Mindhunter’s” endgame, as Fincher and his team threaded out Rader’s introduction to the show throughout the first and second seasons.

While Fincher expressed hope in returning to “Mindhunter” one day, he also doubled down on the fact the series is dead for now and not developing any new episodes. As the filmmaker said, “I don’t know if it makes sense to continue. It was an expensive show. It had a very passionate audience, but we never got the numbers that justified the cost.” Fincher added, “I certainly needed some time away. We had all hands on deck to finish [season two] and we didn’t have a ton of scripts and a ton of outlines and a bible standing by for season three. I’ll admit I was a little bit like ‘I don’t know that I’m ready to spend another two years in the crawl space.’” In his interview with Vulture, Fincher said how “Mindhunter” forced him to spend six to seven months a year for over three years in Pittsburgh in order to work on the series. “We had done the first season of ‘Mindhunter’ without a showrunner, with me pinch-hitting on a week-by-week basis,” the director said. “We started getting scripts for the second season, and I ended up looking at what was written and deciding I didn’t like any of it. So we tossed it and started over.” Head over to Variety’s website to read Fincher’s latest thoughts on the future of “Mindhunter” in their entirety.
