The first trailer for Gillian Anderson and Jason Isaacs' new movie is here

The Salt Path starring Gillian Anderson and Jason Isaacs has released a first trailer ahead of its cinema release.

Premiered at Toronto International Film Festival earlier in the year, the film from first-time director Marianne Elliott adapts the real-life story of Raynor Winn and her husband Moth.

The couple set out on the South West Coast Path — the longest uninterrupted path in England — after a business deal gone wrong left them homeless.

Raynor then chronicled their journey as well as Moth's corticobasal degeneration diagnosis in a book that was intended as a birthday present for her husband, but became a hit when it was published in 2018.

In the trailer, Raynor (Anderson) and Moth (Isaacs) embark on their journey and can be seen struggling with the elements and experiencing financial hardships. Their ordeal continues when Moth receives his diagnosis and is informed that there's currently no cure for his degenerative brain condition.

Amid the heartbreak, the pair grow closer together thanks to the the time spent in nature, as well as forging a number of new friendships as they go along the path.

The film is written by Rebecca Lenkiewicz, who also penned the scripts of Keira Knightley's Colette, Disobedience (starring Rachel Weisz and Rachel McAdams), and She Said (featuring Carey Mulligan and Zoe Kazan).

Alongside Anderson and Isaacs, The Salt Path also stars Ted Lasso's James Lance as Grant and Luther's Hermione Norris as Polly.

Meanwhile, Anderson will soon return to TV in Netflix's upcoming Western series The Abandons, alongside Game of Thrones' Lena Headey, The Sandman's Patton Oswalt and Lucas Till.

A release date for The Salt Path is yet to be announced.
