MI5 agent Worricker returns this Sunday and next (November 9 and 16) with Turks & Caicos and Salting the Battlefield (parts 2 and 3 of the Worricker Trilogy):
Page Eight (shown in 2011), Turks & Caicos, and Salting the Battlefield
form The Worricker Trilogy—three gripping films that follow the
exploits of the intensely private and scrupulous Worricker—from MI5
headquarters in London to exile on a Caribbean island to life on the run
with his former lover and fellow agent Margot Tyrrell (Helena Bonham
Carter). A spy who prefers the black-and-white certainties of the Cold
War, Worricker (Bill Nighy) finds himself increasingly out of his
element as the distinction between ally and enemy dissolves into the
amorphous alliances of the 21st century.
Writer-director David Hare has done it again. The all-star cast includes Oscar winner Christopher Walken, and Oscar® nominees Winona Ryder, Helena Bonham Carter, Ralph Fiennes, and Judy Davis. Also starring are Rupert Graves, Saskia Reeves, and Ewen Bremner.
Although it would be good to view Page Eight, it's not essential. I did find Page Eight on Netflix.
