Roar! Sarah Paulson, 41, let loose at the American Crime Story premiere after party at the W Hotel, Los Angeles, on Wednesday night, alongside co-star Courtney B. Vance

Sarah, who plays the role of Marcia Clark -- the head prosecutor in the 0.J. Simpson murder case -- in FX's mini -series, gave Courtney her best scary face.

Mouth wide-open and brows furrowed, she roared while raising a clawed hand. However, Courtney wasn't fazed by her actions and simply smiled back at her while gently holding her wrist.

The actress dressed in an elegant dark pink dress with a metallic waistband and carried a chunky gold clutch.

By Stella McCartney, Sarah's gown features waist defining mesh panels, a halter neck and a gold belt which works to accentuate her hourglass shape even more. This 'Saskia' dress has come in many colours but we do love Sarah's raspberry version.

The new TV series centres around the O.J. Simpson trial which took place from 1994 to 1995, and will see Cuba Gooding Jr. play the role of O.J. and Travolta as defense lawyer Robert Shapiro.

The former American football star was cleared of murdering his ex-wife and Kris Jenner's best friend, Nicole Brown Simpson, and Ronald Goldman. 

Former friends star David portrays defense lawyer Robert Kardashian and Selma his wife Kris, now known as Kris Jenner.

Producer Nina recently teased in an interview with MTV News: 'For us, the O.J. story is so much more about race in America, the relationship between white police and a black community, the birth of a 24-hour news cycle, and of reality TV.

'The violence is very sobering, but it is very, very restrained, because the story is much more about the trial and the circumstances and the cultural response, two years after the L.A. riots, and how the city and the country and the world responded to these events.

'It’s a very, very different show than American Horror Story, and very respectful of the people involved.'

The 10-episode true-crime anthology series American Crime Story: The People v. O.J. Simpson premieres February 2 on FX.
