"The Twilight movies for me [are] a love story. But it's a dark love story. And I think the best way to describe the song is: it's the darker side of love. I think that pretty much sums it up,” Mars told Billboard.biz of the song.

The penultimate movie in Stephenie Meyer's vampire saga is due in theaters on Nov. 18 of this year, with Part 2 scheduled for Nov. 16, 2012.
