I don't know if I'd have called Depp "iconic" before Pirates.
The point is that movies are much higher risk/reward than theme parks. Even a poorly received theme park expansion has years or even decades to make back its money. The fate of a movie like Oz, one way or the other, could be decided in a single weekend.
At this point, Iger should be much more concerned with Oz than NGE.
Yes. ... Depp created an iconic character in Captain Jack Sparrow.
I wouldn't call him an iconic actor, though. But I have liked or loved almost every film he has ever been in. It's nice to see a local guy and high school drop out make good.
