Netflix Series ‘Mindhunter’ Stars Jonathan Groff As FBI Agent

His TV fans know him as Patrick in HBO’s “Looking,” and as Jesse St. James in “Glee.” His movie fans know him as the voice of Kristoff in “Frozen.” And his theater fans? They know him as the pouty, thoroughly annoyed King George in “Hamilton.”

This week, fans will see Jonathan Groff in an entirely new sort of role — as an FBI agent, trying to get into the mind of serial killers, in the new Netflix series “Mindhunter.”

The series takes place in the ’70s — think Son of Sam and Charles Manson — and is produced, and directed in part, by David Fincher, who knows his way around a gritty crime story, having directed “Gone Girl” and “Zodiac.” It’s based on the book “Mindhunter: Inside the FBI’s Elite Serial Crime Unit” by John Douglas, who spent many years developing psychological profiling to probe the minds of the country’s worst killers.
