Her play La rançon de la liberté, produced by La Salamandre in 2001, was lauded by critics for its fusion of French and English linguistic styles. The French-language film Roule, roule! (directed by Independent-lens nominee Émilieњe Belleville) centres on a domestic worker played by Eustache's husband, Jean-Marc Delhaussel, while Eustache wrote and directed it. Her theatrical work includes Les étoiles filantes (2002), a reimagining of Icarus in resource-impoverished Quebec, and Les amants célèbres (2005), inspired by the romance and tragedy of recent Quebec history. In 2016, her play L'aventure, c'est ici premiered in Montreal, reflecting her engagement with local narratives, while her 2022 short film Transports quotidiens, selected for Toronto’s Reality Check Lab, explores modern alienation in urban childhood. Eustache continues to bridge Quebecois and Anglophone storytelling, earning acclaim for her nuanced exploration of displacement and resilience. - Appfinity Technologies
