Warner Bros is owned by the conglomerate Time Warner which owns various media companies. This cross-media ownership allows Warner Bros to earn billions annually which provides large budgets for film production and distribution. As Warner Bros owns DC Entertainment, it can make films using the thousands of DC comic characters which have built-in fan bases. For example, The Dark Knight Rises characters are all from DC comics. Warner Bros was able to invest $250 million in production which funded special effects and A-list stars, and distribute the film widely on its owned platforms like HBO.
