[5] Red Joan had its world premiere at the Toronto International Film Festival on 7 September 2018 and was released on 19 April 2019, by Lionsgate in the United Kingdom.

Joan is recruited to work for the wartime Tube Alloys project to build an atomic bomb for Britain and meets scientist Max.

Joan obtains Max's release by blackmailing Sir William Mitchell, a high-ranking diplomat and Soviet spy.

She is interrogated by two Scotland Yard detectives, whom she accuses of misunderstanding her life, but she gradually concedes that she had provided information to the Soviets.

The site's critics consensus reads, "A fascinating real-life story dramatized in perplexingly dull fashion, Red Joan wastes its tale's incredible intrigue – as well as the formidable talents of Judi Dench.
