Batman is a 1943 black-and-white 15-chapter theatrical serial from Columbia Pictures, produced by Rudolph C. Flothow, directed by Lambert Hillyer. The serial is based on the DC Comics character Batman who first appeared in Detective Comics #27 in May of 1939. It stars Lewis Wilson as Batman and Douglas Croft as his sidekick Robin. The villain is an original character named Dr. Daka, a secret agent of the Japanese Imperial government played by J. Carrol Naish. Rounding out the cast are Shirley Patterson as Linda Page, Bruce Wayne's love interest, and William Austin as Alfred the Wayne butler.

Batman is notable for being the first appearance on film of Batman and for debuting serial story details that quickly became permanent parts of the Batman comic's mythos: the Bat's Cave and its secret entrance through a grandfather clock inside Wayne Manor. The serial also changed the course of how Alfred Pennyworth's physical appearance was depicted in Batman stories. At the time Batman was released in theaters, Alfred was a portly gentleman in the comics. Subsequent issues suddenly portrayed Alfred as trim and sporting a thin mustache, following actor William Austin's portrayal.
