"With much of its production pipeline fueled by four mega-brands (Lucasfilm, Pixar, Disney Animation and Marvel Entertainment), no single greenlight process applies to any one film. "The very term 'greenlight' is sort of outmoded here," notes one executive.
In the case of Lucasfilm, authority rests with its president, Kathleen Kennedy, and Horn (to whom she reports), but the final say on each movie also involves Disney Studios president Alan Bergman and even Disney CEO Bob Iger.
The same group greenlights the Marvel movies, with Marvel Studios president Kevin Feige replacing Kennedy. With Pixar and Disney Animation, Feige plays no role, but chief creative officer John Lasseter does. While Lasseter does not report to Horn, Horn gets to weigh in, as does Iger, who is said to have been involved in a pricey revamp of
Zootopia late in its production.
Even in-house Disney product is similarly diffuse. "It's inconceivable that if Disney is developing
Beauty and the Beast, which crosses into all our ancillary businesses, Alan wouldn't discuss that with Bob," says one executive."
