The Dark Knight (2008)
Christopher Nolan's 2008 Batman flick, starring Christian Bale, Heather Ledger and Gary Oldman, is far better than anything I've seen in the genre - Heather Ledger was absolutely superb as the Joker. There were several posters for the movie, but this one stands out for me, especially how the bat symbol doubles up as the Joker's make-up/blood smeared mouth.
