Tony Scott famously didn't care about the time travel plot of Déjà Vu which freaked out the writers of the film. As they said, he cared more about the action and surveillance aspects of the movie. He famously cared a lot about surveillance, as visible from his previous Jerry Bruckheimer collaboration Enemy of the State. And that means, that a sort of sci-fi surveillance movie, marks Déjà Vu as the closest thing Tony Scott did to Steven Spielberg's Minority Report.
