In 2019, Eisley stepped into the lead role of Fauna Hodel in TNT’s limited drama series I Am the Night, directed by Patty Jenkins and co-starring Chris Pine. Based on true events surrounding the infamous Black Dahlia murder mystery, the project demanded authentic period recreation rather than stylized modern glamour.
Jenkins pushed Eisley to abandon conventional contemporary actor mannerisms. Her physical presence had to mirror a young woman from 1965 Reno navigating systemic prejudice and horrifying family discoveries. Eisley adopted a grounded, cautious physical demeanor, shedding modern gym-sculpted mannerisms in favor of naturalistic movement. Critics widely praised her performance, demonstrating that her versatility depended on nuanced body language rather than reliance on genetic resemblance.
