Fiona Dourif is no stranger to scares and thrills. Best known for her work across the Chucky franchise -- including multiple roles in SyFy's Chucky series -- she also stole scenes as the vicious Bart Curlish in Dirk Gently's Holistic Detective Agency. That's what makes her appearance in On Fire so surprising. In Cineverse's survival thriller, Fiona plays a character as grounded as they come: Sarah Laughlin, a wife and mother determined to keep her family alive in the middle of a wildfire.
