27 Actors That Underwent Killer Transformations For Roles In True Crime Shows

Why are we so obsessed with true crime?

While it feels like the true-crime genre is a recent fad, it was actually popularized in 1966 by Truman Capote’s book In Cold Blood, which was adapted into a film of the same name the following year by Richard Brooks. It’s just that the invention of the internet and streaming platforms has provided instant access to podcasts and shows about gripping tales of crime.

The 2020 pandemic and lockdown left people with a lot of free time and a desire for escapism, which helped true-crime stories thrive. So, if there has been a killer, a kidnapping, a found body, or even a gun-wielding, heterosexual husband-grooming (with crystal meth) exotic animal park owner with a temper, chances are it’s been a central plot in a docuseries on Hulu, Netflix, or a podcast.

Adweek has observed that there has been a “dramatic increase” in interest in the true crime genre, with several true-crime shows ranking among the top 10 on Netflix in April 2021. But for shows like The People v. O. J. Simpson: American Crime Story, The Act, or Law & Order: True Crime, actors had to undergo some serious transformations.

Portraying a real person can be intimidating in general, but portraying a real-life murderer? That’s got to be some heavy stuff.

However, there have been some incredible actors who rose to the occasion. That’s why we compiled a list of 27 actors who underwent killer transformations for their roles in true crime shows.
