Short films

The Seed is a short film that takes us on an allegorical journey through a fallen world. Without succumbing to futility or despair, this simple yet authentic parable speaks to the urgent need for action on the interrelated crises of climate change and environmental degradation.

The Search for Greta – A short film about hope as we teeter on the cusp of an apocalypse. Set against the backdrop of the world’s largest climate march that took place on September 27, 2019, in Montreal, the protagonists in this short experimental documentary set out to find Greta Thunberg amid the half-million protestors. Despite being overwhelmed with the hopelessness of our current situation a lofty dream is emerging from within the womb of this dystopian nightmare. An inclusive narrative is being born that consolidates our understanding and our purpose.  We find hope even as we teeter on the brink of an apocalypse, as we discover a movement emerging from the ashes of this dying world. As we hurdle toward an uncertain future, we discover that action is the antidote to apathy and despair.
