Cars the movie came out over a year after Eisner announced he was stepping down so I'm not sure how that's possible. I'm not a big Iger supporter, but he was very much in charge of the company when the stock tanked and Carsland was ramping up construction.
Here's the timeline:
May, 2004 - Roy Disney Jr. via his Save Disney campaign publicly demands that Michael Eisner resign
Summer, 2004 - Corporate politics worthy of Macbeth swirl in Burbank
September, 2004 - Michael Eisner announces he will resign when his contract expires in September,
2006
2005 - Roy Disney Jr. isn't satisfied and continues to maneuver Eisner out, Iger ascends as top choice
Summer, 2005 - Deal is reach to have Eisner resign a year early
September 30, 2005 - Michael Eisner resigns and vacates the Board, a year early. Company releases statement that Michael Eisner
"No longer provides services to the Walt Disney Company". Bob Iger named CEO and replacement.
Autumn, 2006 - Al Lutz begins a series of Miceage articles detailing the big budget plans to fix and expand DCA. Online critics of Lutz scoff.
2007 - Al Lutz continues the drumbeat of DCA rumors, claiming it will be an "extreme makeover" of the park with a possible name change
October 15th, 2007 - Al Lutz announces the big DCA project reveal will happen on Wednesday the 17th.
October 17th, 2007 - Bob Iger and Jay Rasulo hold a press conference to announce the re-Imagineering of DCA at a cost of over $1 Billion. Bob Iger describes DCA to the media thusly
"In the spirit of candor, this park has been challenged since opening".
October 18th, 2007 - Al Lutz says
"I told you so".
December, 2007 - US economy officially enters recession on rapidly weakening numbers
March, 2008 - Lehman Brothers fails, housing market tanks
October, 2008 - US bank panic & stock market crash, global financial pandemonium
Winter 2008-09 - Great Recession begins, work on DCA project continues at full speed (World of Color, Pier remake, Little Mermaid ride, etc.)
July, 2009 - Unemployment rate hits 9.4%, Groundbreaking on Cars Land begins in the old Disneyland parking lot
June 15, 2012 - Cars Land & Buena Vista Street open and a remade DCA becomes wildly successful
Michael Eisner was certainly there until 2005 as DCA failed miserably, and he may have begun discussions on what to do about it by '05. But the shepherding and approval of the project, and most importantly the funding and commitment in the midst of scary financial times, appears to be all Bob Iger.
That's good news for whatever they are doing at DHS. So long as they begin in earnest by the time Bob Iger resigns in 2018.
