The casting change sees Weaver, known for her powerful performances in films like 'Animal Kingdom' and 'Silver Linings Playbook', take on a pivotal role in the series currently filming in Western Australia. Her recent television credits include 'Yellowstone', 'Picnic at Hanging Rock', and 'Secret City', demonstrating her versatility across both film and television.

'Two Birds' centers on Constable Izzie Cornwell, played by Sheridan Smith, who arrives from the UK seeking a fresh start in a remote Australian mining town. However, a misstep quickly entangles her in a dangerous web of deceit and guilt, promising a tense and gripping narrative for viewers.

Alongside Weaver and Smith, the series boasts a strong ensemble cast including Stephen Peacocke ('Five Bedrooms'), Colin Friels ('Water Rats'), Fiona Button ('The Split'), Eva Morgan ('The Gathering'), Harry Greenwood ('Klara and The Sun'), Nic Cassim ('Mr Inbetween'), Victoria Fowler ('Dalliance'), Lila McGuire ('The Twelve'), Kit Jeakings-Bull ('Invisible Boys'), Matthew Pearce ('Home and Away'), Sarah Roberts ('Scrublands'), and Matt Day ('Rake').

Behind the scenes, the project is helmed by experienced talent. Patrick Spence, known for his work on 'Mr Bates vs the Post Office', produces through his AC Chapter One banner, with Martha Coleman from Third Act Stories also attached. The scripts are penned by Helen FitzGerald ('The Cry') and Megan Palinkas ('Heartbreak High'), while James Griffiths ('The Ballad of Wallis Island') and Corrie Chen ('Good Cop/Bad Cop') share directing duties. ITV Studios is handling international distribution for the series.

The announcement of Weaver's involvement comes amidst a busy period for Stan, having been revealed during its recent upfronts presentation, which also highlighted new projects featuring Rachel Griffiths, Angourie Rice, and Anna Friel, as well as a revival of the beloved 'McLeod’s Daughters'.
