Gary Oldman has some form playing conflicted spy types on screen, most notably his turn as George Smiley in Tinker Tailor Soldier Spy. He'll portray a very different type of agent in the Apple TV+ adaptation of Mick Herron's Slow Horses books.
Herron's successful, entertaining and often darkly comic series follows the less-than-by-the-book behaviour of Jackson Lamb, a brilliant but frequently furious leader of a group of MI5 misfits, who all end up posted to his Slough House facility after screwing up missions (or being maneuvered into doing so by Thames House rivals).
Graham Yost, no stranger to bringing unorthodox literary heroes to life with Justified, will be the main executive producer, while regular Armando Iannucci collaborator Will Smith is on hand to write the scripts, and to keep the British feel intact. Oldman will play Lamb, and we'll be watching to see who is cast as the various troubled types around him.
