Rogue Agent is a 2022 British biographical mystery drama thriller film directed by Adam Patterson and Declan Lawn in their feature-length debut, from a screenplay the pair co-wrote with Michael Bronner based on the unpublished[4] article "Chasing Agent Freegard" by Michael Bronner.

Gemma Arterton also stars as the person who brought him down, with additional cast members including Shazad Latif, Marisa Abela, Edwina Findley and Julian Barratt.

Robert poses as an MI-5 agent, and asks three people - Sophie, Mae and Ian - for assistance in capturing members of the IRA.

The PI comes back to Alice and tells her he has dug up some past court judgments against Robert - that he was stalking and harassing a Julie Harper.

Alice meets with Sophie's parents, who say she called them occasionally to inform them that she was safe, but they could tell that she was brainwashed, because she asked for her share of the inheritance - £300,000 - only to promptly disappear again.

The policeman assigned to the case, Sonny, is unable to tell if a crime has been committed since it was a joint account, but decides to investigate anyway.

[5] By June 2020, Adam Patterson and Declan Lawn were attached to co-direct the feature from a screenplay by Michael Bronner.

[6][7] In May 2021, it was reported that Night Train Media would also finance the film, then retitled Freegard, and that Gemma Arterton, Shazad Latif, Marisa Abela, Edwina Findley and Julian Barratt had joined the cast.

That July, Sarah Goldberg, Jimmy Akingbola, Freya Mavor, Rob Malone, Philip Wright, Michael Fenton Stevens and Charlotte Avery were added to the cast.

The website's consensus reads, "Even if it isn't as engaging as the real-life story that inspired it, Rogue Agent remains a well-acted and appealingly twisty suspense thriller.
