The Brink of War Filming Locations and Cast Details

Rather than rebuilding one of the Cold War’s most famous diplomatic meetings on a Hollywood soundstage, “The Brink of War” puts its actors inside the room where history actually happened. Michael Russell Gunn’s political drama revisits the tense 1986 Reykjavik Summit, when U.S. President Ronald Reagan and Soviet leader Mikhail Gorbachev met in Iceland to discuss nuclear arms reductions. Jeff Daniels plays Reagan, Jared Harris takes on Gorbachev, and J.K. Simmons portrays Secretary of State George Shultz. The movie concentrates on the exhausting negotiations, disagreements and small shifts in trust that brought the two superpowers unexpectedly close to a major nuclear agreement.

That history shaped the production from the beginning. Originally developed under the title “Reykjavik,” the film was shot extensively in Iceland in fall 2024. More unusually, Gunn secured access to Hofdi House, the genuine summit venue, allowing Daniels and Harris to occupy many of the same rooms, chairs and surroundings used by Reagan and Gorbachev nearly four decades earlier.

Where was The Brink of War Filmed?

Hofdi House, Reykjavik

Hofdi House at Borgartun 1 in Reykjavik is easily the most important filming location in “The Brink of War.” Reagan and Gorbachev held their October 1986 summit inside the waterfront property, and the filmmakers returned there for the central negotiation sequences. Reykjavik City still owns the house and uses it for official receptions.

The production reportedly paid the city 6.3 million Icelandic krona to rent Hofdi. Local production company Pegasus Pictures held the property through November 10, 2024, giving the crew enough time to handle extensive interior and exterior work. Jeff Daniels, Jared Harris and J.K. Simmons were photographed filming outside the building in October.

What makes the location especially valuable is how little needed to be invented. Pegasus producer Elli Cassata explained that the actors could sit around the same table and use furnishings associated with the original summit. Filming came with strict preservation rules. Crew numbers inside the house were restricted, equipment could not simply be attached wherever convenient, and the production had to respect the building and grounds rather than treat them like an ordinary set.

That inconvenience seems like a reasonable trade. A replica could reproduce the walls, but it could not give Daniels and Harris the unusual experience of performing the negotiations in the place where Reagan and Gorbachev actually faced each other.

Sæbraut and the Reykjavik Waterfront

The production also moved outside Hofdi and onto Sæbraut, the major coastal road running beside the house. Reykjavik officials temporarily closed sections of the road for filming in October 2024, including a closure on October 26 between Kringlumyrarbraut and Snorrabraut. Katrinartun was also closed during the shoot.

Period filmmaking created an obvious problem here. Modern Reykjavik does not look exactly as it did during Reagan’s visit in 1986, and contemporary traffic infrastructure had to be controlled or kept outside the frame. The street work allowed Gunn to recreate the movement surrounding the summit, including the official vehicles, security presence and activity around Hofdi, without modern traffic intruding on the illusion.

Blue Lagoon

Away from the negotiation rooms, “The Brink of War” uses one of Iceland’s most recognizable landscapes: the Blue Lagoon on the Reykjanes Peninsula. Variety documented Gunn and cinematographer Magdalena Gorka preparing a shot at the geothermal location during production.

The lagoon provides a striking visual break from the enclosed political drama at Hofdi. Its pale geothermal water, steam and surrounding lava fields instantly establish Iceland without requiring a conventional skyline shot. Public production reporting confirms the Blue Lagoon as a filming location, although an official scene-by-scene breakdown has not been released.

Mosfellsdalur and Skeggjastadir

The crew went beyond central Reykjavik for additional location work. Skeggjastadir in Mosfellsdalur was specifically named by Pegasus while filming was underway. Mosfellsdalur lies northeast of Reykjavik and offers farmland, mountains and open countryside that contrast sharply with the controlled diplomatic environment inside Hofdi.

The production has not publicly identified exactly which finished scenes belong to Skeggjastadir. It is therefore safer to treat it as a confirmed filming site without attaching a particular event or character sequence to the property.

Reykjanes Peninsula

The wider Reykjanes Peninsula was another confirmed part of the Iceland shoot. Its volcanic terrain, exposed roads and largely treeless horizons gave the production access to landscapes that immediately establish the geographic isolation surrounding the summit.

Reykjanes also contains the Blue Lagoon, but production reports list the peninsula separately, indicating that the filming footprint extended beyond the geothermal resort itself. Some secondary location guides have attributed additional specific landscape shots to sites around Iceland, but those claims have not been documented as clearly as Hofdi, Sæbraut, the Blue Lagoon, Mosfellsdalur and Reykjanes.

When Was The Brink of War Filmed?

Principal photography began in Reykjavik on October 15, 2024, after the project had been announced under its original “Reykjavik” title. Filming continued into November, with Hofdi leased until November 10 and the wider production expected to conclude around the middle of the month. Iceland’s production rebate and experienced local crews helped make an unusually location-heavy approach financially practical.

There was another unusual connection to the real summit behind the camera. Photographer Pete Souza, who documented the 1986 event, returned as the still photographer for the film production. That gave the filmmakers someone on set who had actually witnessed and photographed the people and place they were recreating.

The Brink of War Cast

Jeff Daniels leads the cast as Ronald Reagan, with Jared Harris as Mikhail Gorbachev and J.K. Simmons as George Shultz. Hope Davis plays Nancy Reagan, while Branka Katic portrays Raisa Gorbacheva. Aya Cash appears as journalist Cleo, and Guy Burnet plays Alexander.

The political ensemble also includes John Ross Bowie as arms-control official Kenneth Adelman, Adrian Rawlins as diplomat Max Kampelman, Johannes Haukur Johannesson as Richard Perle, Vladimir Kulich as Soviet military leader Sergey Akhromeyev, and Stephen Brennan as arms negotiator Paul Nitze.

“The Brink of War” could easily have treated Iceland as background scenery for a Washington-focused historical drama. Instead, the production returned the story to the small Reykjavik house where the confrontation actually unfolded. Hofdi’s rooms, Reykjavik’s waterfront and the harsher landscapes beyond the city give the film something production design alone cannot provide: the physical geography of the event it is trying to reconstruct.
