Couple: Batman and Catwoman
Alright, technically Michael Keaton’s Batman and Michelle Pfeiffer’s Catwoman are adversaries in Batman Returns but they sure do generate some “love you/hate you” heat throughout the movie. In an overall dark movie, Catwoman’s over-the-top seduction (that lick!) of the brooding Bruce Wayne/Batman provides some sexy shenanigans with a tinge of kinky that makes their chemistry palpable. Until we see if Anne Hathaway and Christian Bale have their own sparks in The Dark Knight Rises, this is the Catwoman/Bats on-screen pairing to beat.
