--The series begins very shortly after "Superman Returns" (technically, the first meeting takes place in the middle of the movie) and very shortly after the as-yet-unknown events of the second Batman movie. Batman has been active for about three or four months now. --The series takes "Batman Begins" as its departure point. "The Dark Knight" was released after the series started, so those events don't happen as they do in the movies (in the case of Harvey Dent, they're quite different).
