The stars will appear alongside writer/director Alice Englert, as well as Ana Scotney, Dasha Nekrasova, Karan Gill, and Marlon Williams, according to Deadline.
The film follows Lucy (Connelly), a former child actress who seeks enlightenment at a retreat led by spiritual leader Elon (Whishaw) while navigating a close, yet turbulent relationship with her daughter, Dylan (Englert).
Englert will make her feature directorial debut with the dark comedy shot in New Zealand. The film is being financed by a number of different parties, including the New Zealand Film Commission and the New Zealand Screen Production Grant.
Englert, the daughter of Jane Campion, previously directed Whishaw in the 2017 short film Family Matters, which she also wrote and starred in. Her other short, The Boyfriend Game, took out the Best Achievement in Screenplay award at the 2017 St Kilda Film Festival.
