The Netflix–Warner Bros deal instantly grants Netflix rights to massive IP like Harry Potter and DC, but the box office data highlights the enduring value of theatrical hits. Barbie's $1.45B worldwide haul tops the list, proving original blockbusters are WBD's true goldmine for subscriber-driving content. Harry Potter (eight films grossing $7.6 billion worldwide) and The Dark Knight trilogy (over $2.8 billion) highlight WB's reliable mega-franchises. Netflix's strategy post-merger will be to maximise this catalogue, turning theatrical hits into ongoing, high-value streaming content.
