| "I once thought I could save the world... now look at it"
— Spoilers for Deus Ex: Mankind Divided follow!
James "Jim" Miller is the director of the Central European branch of Task Force 29, an international counter-terror force funded by Interpol. He is Adam Jensen's boss in Deus Ex: Mankind Divided and the Deus Ex Universe: Children's Crusade comics.
Miller is a direct and decisive leader, committed to his job and passionate about protecting civilians.
He has gone through his entire career with unwavering respect for the chain of command. But lately, questionable orders passed down by his boss are causing Miller to balk, resulting in him starting to reconsider his stance.
Miller is incredibly tight-lipped when inquired about his personal life. Reading his e-mails reveals that he had an ex-husband and adopted children, including a daughter who suffers from an unspecified bone condition which is causing her great pain and would eventually cripple her. From his writing, he appears to be quite torn about the idea of giving her augmentations to cure it, revealing a sensitive and gentle side one would never imagine in the stone-cold Miller.
- During the final mission in London, Miller is badly injured. Jensen can save him by using the Antidote found earlier in a Palisade Data Vault in Prague during The Heist. Saving Miller will unlock the He's [Not] Dead, Jim achievement.
- According to the Art of Deus Ex Universe, Jim Miller's appearance is based on the actor Rutger Hauer as a reference to his character Roy Batty from Blade Runner.
- On one of Miller's computers is an e-mail from Bennet, an old comrade during his time in the Special Forces. This is likely a reference to the 1985 film Commando, where Miller's voice actor, Vernon Wells, portrayed the character of the same name.
- He's going through a particularly emotional divorce, featuring classic acts like his spouse laying claim to the family vault, the children, and everything not nailed down.
