Batman's crusade against crime has captivated moviegoers since the Golden Age of cinema. Passing the cape and cowl from one actor to the next is integral to the hero's big-screen legacy, and many have served as Gotham's protector. With so many iterations and competing visions contributing to the mythos, it's easy to feel overwhelmed. Twelve live-action films devoted solely to Batman were theatrically released in the modern age of movies; two are animated, and several others feature him as a supporting character or cameo. In total, the timeline spans more than eighty years.
