'Mindhunter' fan puts Charles Manson scene side-by-side with real 1981 interview

For anyone who hasn't yet seen the gripping Netflix crime drama, Mindhunter, it revolves around a team of FBI agents as they try to get inside the heads of some of America's most infamous serial killers.

For many viewers, a real highlight was Damon Herriman's performance as notorious cult leader Charles Manson in season 2, episode 5.

Fun fact: the Australian actor also played Manson in the new Quentin Tarrantino movie, Once Upon A Time... In Hollywood.

But back to Mindhunter. While I'm assuming most people wouldn't be aware of how Herriman's portrayal compares to Manson's real-life persona - if you happen to have seen interviews or other kinds of footage featuring Manson, you'll know just how creepily accurate it is.

And luckily for you - providing you are a fan of Mindhunter and have watched Herriman as the sadistic criminal - someone has very kindly taken the time to put together one of the scenes side-by-side with an actual interview with Manson from 1981.

The resemblance between Herriman and the infamous killer is absolutely uncanny, and I'm certainly not just talking about physical appearance.

The video shows the 49-year-old actor in an extended sequence in which Manson comes face to face with FBI criminal profilers Bill Tench (Holt McCallany) and Holden Ford (Jonathan Groff).

Herriman perfectly encapsulates the mannerisms, voice and presence of the man who orchestrated the mass murders of nine people, including actress Sharon Tate.

The interview, courtesy of 60 Minutes Australia, which was featured in the side-by-side video was Manson's first since going to prison.

And as the description for official 60 Minutes Australia YouTube upload reads, the "interview caused such a stir. Not only do we see Manson, cold and unrepentant—but we hear his thoughts on gaining parole and getting out of prison 'to play like a human.'"
