Sibylla Deen is an Australian-born actress and filmmaker, raised in Sydney and now based in California. She has appeared in lead roles in Lies We Tell and series including Tyrant (FX), Tut (Spike TV), The Last Ship (TNT), and The I-Land (Netflix), and has written and directed plays, cultivating a deep connection to storytelling.

In recent years, Deen has turned her focus to her lifelong passion for nature, animals, and wild horses. Following the pandemic and a near-fatal bout of dengue fever, she found herself drawn into the quiet, grounding world of wild horses, discovering their intelligence, presence, and capacity to heal.

Her viral New Year’s Day foal rescue introduced millions to this work, but her bond with horses began in childhood. Blending her performance experience with years of intimate observation, Deen now shares the transformative connections she has found between humans, animals, and the natural world.
