See David Fincher Return to Serial Killer Genre With 'Mindhunter' Teaser

Netflix series focuses on FBI's Elite Serial Crime Unit in 1970s

'Se7en' and 'Zodiac' director David Fincher returns to the serial killer genre with the Netflix series 'Mindhunter,' which dropped its teaser trailer.

Se7en and Zodiac director David Fincher returns to the serial killer genre with the Netflix series Mindhunter, which dropped its teaser trailer Wednesday.

Based on the book Mind Hunter: Inside FBI’s Elite Serial Crime Unit, the series takes place in the late Seventies and focuses on the feds' serial killer profiling squad.

According to the Mindhunter synopsis, "An agent in the FBI's Elite Serial Crime Unit develops profiling techniques as he pursues notorious serial killers and rapists."

The unsettling teaser doesn't provide much footage of the series, relying instead on a bloody Rorschach test to display the psychological side of the series. "You like truffles? You got to get in the dirt with the pigs," an agent says in voiceover about profiling serial killers.

Jonathan Groff and Holt McCallany star as Mindhunter's FBI agents, with Fincher, Amy director Asif Kapadia and Amityville Horror reboot director Andrew Douglas among those helming the 10-episode first season.

Mindhunter will hit Netflix in October.
