Jennifer Holland is an American actress best known for her role as Emilia Harcourt in James Gunn’s HBO television series Peacemaker (2022–2024), where she emerged as a key part of the show’s core ensemble. Her performance helped establish Harcourt as one of the more grounded and serious presences within Gunn’s DC projects, balancing action-driven storytelling with character-focused moments. Holland’s most prominent later work has been tied to DC Comics projects under Gunn, beginning with her debut as Harcourt in The Suicide Squad (2021), followed by appearances in Black Adam (2022) and Shazam! Fury of the Gods (2023). She later carried the role into animation with Creature Commandos (2024–), making her one of the few performers to portray the same character across DC’s live-action and animated continuities.
