Batman: Assault on Arkham

Batman: Assault on Arkham is an animated action thriller set in Gotham City. When the Riddler steals classified government information and is locked away in Arkham Asylum, the secret operative Amanda Waller assembles a team of imprisoned criminals to break into the facility and retrieve it. Deadshot leads the group, which includes Harley Quinn and other villains drawn from Gotham's underworld. Batman, meanwhile, is pursuing his own investigation, and the two missions collide inside Arkham's walls. The situation grows more dangerous when the Joker becomes involved, threatening both the asylum and the wider city, leaving Batman to stop him.

The film was directed by Jay Oliva and Ethan Spaulding. For Oliva it was the tenth of the thirteen films he has directed, arriving between Justice League: War in 2014 and Batman vs. Robin in 2015.

It runs seventy-six minutes and was produced by DC Entertainment, DC Comics, Warner Bros. Animation and Warner Premiere.
