Meanwhile, other filmmakers achieved this by crafting spinoffs from their successful franchises, like Peter Jackson did with The Hobbit after Lord of the Rings, or how Pierre Coffin spun the Despicable Me franchise off to focus on the minions.
Christopher Nolan achieved this with two of his Dark Knight movies, Michael Bay directed two $1 billion Transformers installments, and Joss Whedon helmed both The Avengers and Avengers: Age of Ultron.
According to Forbes, this upcoming milestone has only been shared by a handful of directors in the past, and most of them for multiple entires into the same franchise.
