For nearly a century, Warner Bros. has been in the big-screen business. From the gangster pictures that defined its Depression-era offerings to the “Batman” movies that ushered in its blockbuster phase, the studio has focused on creating stories so action-packed, so need-to-see, that they are tailor-made to lure people from their homes and separate cinema-goers from their hard-earned cash. In the process, the studio helped establish Hollywood as the movie capital of the world.
