A director's attachment to a project doesn’t guarantee its completion, although Christopher Nolan typically follows through once he commits to a film. In contrast, Guillermo del Toro has spent years developing projects that never materialized, losing over a decade on films without shooting a single frame, which must be frustrating given how often it has happened to him.
Since becoming the renowned brand and Oscar-winning filmmaker he is today, Nolan has had the freedom to choose projects with confidence. It is now rare for him to be linked to a film that fails to get made. The only two instances when Nolan dropped out happened before he released The Dark Knight, his first billion-dollar blockbuster.
Contrary to popular belief, the Howard Hughes biopic is not one of these films. Nolan was disappointed when his version was shelved after Martin Scorsese's version was filmed first. That project had the potential to be a defining role for Jim Carrey, but Nolan never officially left directing; the cancellation was due to factors beyond his control.
He did, however, step away from The Prisoner, an intended adaptation of the classic 1960s television series.
"Since he became Christopher Nolan, the brand, the knight of the realm and Oscar winner has been able to do whatever he wants. That means it’s highly unlikely he’ll ever be announced as the director of a movie that never gets made again."
"Nolan was crushed when his version of the story was mothballed after Martin Scorsese got his in front of the cameras first, and it stood every chance of being a career-defining performance for Jim Carrey."
Author's summary: Christopher Nolan rarely abandons projects, with only two pre-Dark Knight films never made, highlighting his remarkable consistency in bringing his films to completion.
