The Dark Knight (2008)

When the menace known as the Joker wreaks havoc and chaos on the people of Gotham, Batman must accept one of the greatest psychological and physical tests of his ability to fight injustice. As Batman, Lt. Gordon and the district attorney continue to dismantle Gotham's criminal underground, a new villain threatens to undo their good work. Christian Bale and director Christopher Nolan reunite following their blockbuster success with Batman Begins! This time, Heath Ledger joins the cast as The Joker, and Aaron Eckhart stars as Harvey Dent in an all-new adventure of The Dark Knight. With the help of Lieutenant Jim Gordon (Gary Oldman) and new district attorney Harvey Dent (Eckhart--Thank You for Smoking), Batman sets out to destroy organized crime in Gotham City forever. The three enjoy early success, but they soon find themselves prey to a rising criminal mastermind known as The Joker (Ledger--Brokeback Mountain), who throws Gotham into anarchy and forces Batman ever closer to crossing the line between hero and vigilante.
