I was kind of stunned to learn that so many of the films ruined by executive meddling turned out to have the same executive responsible: Tom Rothman, formerly of Fox and currently of Sony.
From Variety, here's a short list of his decision-making:
"...Rothman’s reputation for being cost-effective when he was running Fox’s film arm, where he oversaw both
Titanic and
Avatar—two of the highest-grossing movies in history, which
Rothman reportedly opposed making. He
famously, similarly opposed numerous elements of X-Men(such as it having too many X-Men), clashed repeatedly with its franchise’s directors and drove away Bryan Singer, demanded it cut the Sentinels because
he doesn’t like giant robots, and, of course, hired Brett Ratner.
Variety credits all this to Rothman’s “hands-on management style,” something that’s also manifested in clashes with directors like
I, Robot’s Alex Proyas (whom he’s rumored to have tried driving out of the business altogether), and pushing for PG-13 ratings on movies like
X-Men Origins: Wolverine,
Alien Vs. Predator, and
A Good Day To Die Hard. It also admits Rothman has a reputation for having a “prickly personality and a temper,” in addition to his reputation for mercilessly slashing budgets, demanding family-friendly rewrites, passing on new ideas in favor of strip-mining old properties, and turning seemingly surefire Marvel properties like
Daredevil and
Fantastic Four into kiddie glop."
So basically, he's responsible for X-Men: The Last Stand, X-Men Origins: Wolverine, AVP, A Good Day to Die Hard, Daredevil, Fantastic Four (all 3 of them), and opposed Titanic and Avatar. And he's the reason it took more than 10 years to make Deadpool - he HATES the character, and ordered all the changes in X-Men Origins: Wolverine, including removing the mouth from The Merc With The Mouth. That is also why Deadpool says "Hi Tom!" during the leaked test footage.
Good job picking this guy up, Sony.
