[3] A Call to Spy had its world premiere on June 21, 2019, at the Edinburgh International Film Festival, and was released in the United States on October 2, 2020, in theaters and on video on demand.

Film critic aggregator Rotten Tomatoes said it "overcomes a surprising lack of tension with an overall engaging tribute to an oft-overlooked group of World War II heroes.

SOE's "spymistress," Vera Atkins, recruits two unusual candidates: Virginia Hall, an ambitious American with a wooden leg, and Noor Inayat Khan, an Indian Muslim pacifist.

A review by The Times said: "Inspired by true stories, A Call to Spy is a compelling tale of extraordinary courage and sacrifice.... Each woman left an unmistakable legacy and the film is a tribute to their bravery and ingenuity.

Sarah Megan Thomas is the standout here ... not only taking on the film's meatiest role as real-life spy figure Virginia Hall, but also writing and producing the feature."

[29] The Times of India said, "Backed by spectacular performances and strong writing, ‘A Call to Spy’ is a realistic and engaging spy-thriller that packs a solid emotional punch.
