Yesterday the first clip from Batman: The Killing Joke was released. If you weren’t familiar with the graphic novel the animated movie is based on, you’d think that Batman was confronting the Joker.

If you need a refresher, our friend Arris Quinones from Variant has you covered! In the video above, Quinones breaks down the popular graphic novel which is considered one of the greatest Batman/Joker stories ever told. If you want to know what to expect when the movie comes out later this month, definitely check it out!

Batman: The Killing Joke is available for pre-order on Amazon now. The movie hits Digital HD on July 26th, and Blu-ray/DVD on August 2nd. It will premiere at San Diego Comic-Con on July 23rd.
