Jonathan Groff opens up about his roles in 'Mindhunter,' 'Hamilton' and 'Frozen'

— -- In "Mindhunter," Jonathan Groff plays an FBI agent investigating serial killers in the 1970s, and the actor told ABC News he is surprised at how some fans have made the thriller their latest Netflix obsession.

"People are binge-watching it like it's 'Scandal,' but it’s this psychological, cerebral show. It’s very intellectual," Groff said on "Popcorn With Peter Travers." "It’s not a show that you want to watch while you’re emailing or texting. You've got to really focus in. It's a drama, but the response has been so amazing because people are just eating it up, which has been really exciting."

Despite the heavy subject matter, Groff said the show doesn't contain too much blood and gore, and that was always the plan.

"David Fincher is the director, creator, genius behind the show. When he sat me down initially when we were talking about it, he said, 'The whole show is going to be people in rooms talking,'" said Groff. "There’s a violent moment in the first episode in the first scene, but other than that, there’s no gore. It’s a very cerebral, psychological deep dive into the world of criminal profiling and serial killers and crime in the late '70s."

It's not unusual for Groff to work on projects that quickly become fan favorites. "Mindhunter" comes on the heels of his year-long stint as King George in "Hamilton," one of the most successful shows to ever hit Broadway. And before "Hamilton," Groff played the voice of Kristoff in the animated feature "Frozen," one of the most successful Disney animated films of all time.

"It’s so lucky though, you know what I mean? I wish that I could take credit for the success of 'Frozen' and 'Hamilton.' But I just feel lucky to be in ‘em," Groff said.

The actor said that any fans hoping that he can help them score "Hamilton" tickets will be disappointed, however.

"They just never email back now. When I was doing the show for the year, in my contract I had two house seats to every show. I used those two house seats for every show. I was like Santa Claus for a year. I was like Oprah," Groff joked. "Those days are over."
