Batman: Gotham Knight is a 2008 Japanese-American adult animated superhero anthology film based on the DC Comics superhero of the same name. The film consists of six segments produced by Japanese animation studios Studio 4°C, Madhouse, Bee Train and Production I.G in association with DC Comics and Warner Bros. Animation. Set between Batman Begins and The Dark Knight, the segments in the film depict Batman battling against the mob of Gotham City, as well as other villains. Although stated to take place within The Dark Knight trilogy, the producers have acknowledged that the plot from the anthology is not necessarily integral to the main story told within the films. The shorts are written by Josh Olson, David S. Goyer, Brian Azzarello, Greg Rucka, Jordan Goldberg and Alan Burnett. Although all use Japanese anime art styles, each segment has its own writing and artistic style, similar to other DC Universe works and The Animatrix; however, some segments are connected, giving it the nickname, "The Batimatrix". All six segments of the anthology film star Kevin Conroy, reprising his voice role as Batman from the DC Animated Universe.
