In Quantum Of Solace (2008), Tanner (Rory Kinnear) is M’s right-hand man. He plays by-the-book, leading M to explain that things aren’t always what they seem. In Skyfall (2012), Tanner helps M and Bond identify Patrice, protects M during Silva’s attack on the Board of Inquiry, and assists Q in leaving a digital “breadcrumb trail” for Silva to follow.
Spectre was Kinnear’s third instalment as Tanner. He keeps Bond updated with the new head of the Centre for National Security, C’s plans and escorts Bond to receive a smart blood tracking device, an “insurance policy” after Bond’s rogue mission to Mexico. Tanner teams up with Moneypennny and Q to help Bond and M bring down C and Blofeld.
