Where is Treason on Netflix filmed?

Treason on Netflix is filmed entirely in London and Kent. Part of the series was filmed in Borough Market with other locations including Southwark Park and America Street. Meanwhile, in Hertfordshire, Childwickbury Manor was used as a location and south eastern parts of Kent also features.

One of the van stunts was captured on Endsleigh Street as a road closure had to be put in place for film crews to capture the moment on camera. And Gordon Square was said to be chosen because it has plenty of university buildings and businesses which make it perfect to control. 

Filming is said to have started back in January 2022 and wrapped in August 2022, according to What's on Netflix.

Who is in the cast of Treason?

The cast of Treason features Charlie Cox as Adam Lawrence, Oona Chaplin as Maddy De Costa, Olga Kurylenko as Kara Yerzov, Ciaran Hinds as Sir Martin Angelis, and Tracy Ifeachor as Dede.

Another fan put, "Charlie Cox deserves top billing in Hollywood. He is fantastic in anything he stars in."

And a third fan added, "Wow it's so refreshing to see Charlie Cox doing other stuff outside of Daredevil."

Treason Netflix reviews

Reviews for Treason on Netflix are mixed so far, with Vicky Jessop at the Evening Standard (opens in new tab) describing it as "a breathless thriller that lacks bite". But they did praise Olga Kurylenko who is said to "shine" in the pertinent tale of "politics and Russian spies".

Meanwhile, Yahoo! (opens in new tab) reporter Martin Carr,  says it's a "conventional spy thriller with a few surprises". He explained, "For the most part, this feels like a solid ensemble who recognise they might not be in an outstanding piece of work. Everything is by the numbers and ticks every box without any fuss, but ultimately Treason lacks any suspense, even if a propulsive soundtrack might suggest otherwise. Under these constraints there is little that Charlie Cox can do but get by on screen presence, since any semblance of plot seems incapable of helping him out."

And Jasper Rees at the Telegraph (opens in new tab) sums it up as, "Russian spies, double-crossing British spooks, a baby-faced head of MI6 - this 100mph thriller is loopy, self-serious and a lot of fun"
