Co-written by Lanthimos and his longtime collaborator Efthimis Filippou, The Lobster had initially had Zero Dark Thirty actor Jason Clarke previously attached to the lead male role, but the Australian star pulled out over scheduling conflicts with mountaineering disaster movie, Everest.

Lanthimos spoke with humbleness and optimism towards his sixth feature film: "I'm very grateful to have the opportunity to work with such great actors. Their contribution to our film will enrich and expand the world we are trying to create and explore. Furthermore our team of old and new collaborators makes me very confident and excited to start making this film," the director said, via Variety.
