Jojo Rabbit star Thomasin McKenzie, Kodi Smit-McPhee, & Joker actress Frances Conroy are set to co-star in the Jane Campion-helmed Netflix/See-Saw Films drama, The Power Of The Dog. They join previously announced stars Benedict Cumberbatch, Kirsten Dunst & Jesse Plemons.

Campion adapted the pic based on the 1967 novel of the same name by Thomas Savage. The plot follows wealthy Montana brothers Phil (Cumberbatch) & George Burbank (Plemons), who are two sides of one coin. Phil is graceful, brilliant & cruel where George is stolid, fastidious & gentle. Together they are joint owners of the biggest ranch in the Montana valley. It is a place where men are still men, the rapidly modernizing 20th century is kept at bay & where the figure of Bronco Henry, the greatest cowboy Phil ever knew, is revered. When George secretly marries local widow Rose (Dunst), a shocked & angry Phil wages a sadistic, relentless war to destroy her entirely using her effeminate son Peter as a pawn.

Keith Carradine (The Old Man and the Gun, Madame Secretary), Peter Carroll (Crazy Rich Asians) & Adam Beach (Hostiles, Suicide Squad) have also been added to the cast.

See-Saw Films’ Emile Sherman & Iain Canning are producing the pic with Roger Frappier of Max Films, Campion (via Big Shell) & Brightstar’s Tanya Seghatchian. Exec producers are BBC Films’ Rose Garnett, See-Saw’s Simon Gillis & Brightstar’s John Woodward.

Netflix, which picked up the worldwide rights to the film at last year’s Cannes Film Festival, will release the film in 2021 in theaters & on its platform. Transmission Films will release the pic theatrically in Australia & New Zealand.

McKenzie, best known for her breakout role in the 2018 film Leave No Trace, is repped by UTA, Untitled Entertainment, Industry Entertainment, & Gail Cowan Management. Smit-McPhee, most recently seen in X-Men: Dark Phoenix & opposite Eddie Murphy in Dolemite Is My Name, is repped by ICM. Conroy is with Paradigm & Echo Lake Entertainment.
