Wired is not the first to make the comparison between The Adjustment Bureau and Fringe's Observers. While writer-director George Nolfi did a good job of expanding on the original 1954 Philip K. Dick short story, especially with the romance between politico Matt Damon and modern dancer Emily Blunt, he missed a step when he visualized the bureau agents in 60s fedoras:
Members of both groups wear hats and suits. Both carry briefcases or books. Both have existed for centuries on the periphery of human consciousness. Both take orders from unknown superiors and periodically create unintended consequences when they feel compelled to intervene in the lives of the subjects under their watch.
No wonder the outfits looked so familiar. And casting Mad Men's John Slattery only makes the adjustment team's anachronistic uniforms stand out even more.
