What all this proves is that Spielberg is an equal opportunity content provider who, as a corporate player, has left behind a mixed bag of successes and confusions. DreamWorks 25 years ago was intended to be a monster new major presided over by Spielberg as well as by Jeffrey Katzenberg and David Geffen, both of whom now have given up on the movie business. Some 15 movies a year were supposed to emerge from DreamWorks' streamlined new film factories at Playa Vista. The physical studio, of course, never happened, but the production entity kept humming along, depositing an occasional Oscar winner ( American Beauty ) along the way. The exit of Wright after a two-year run (he formerly ran the Turner networks) followed a series of other executive exits including those of Laurie MacDonald, Walter Parkes, Bob Cooper and Stacey Snider. Along the way, outsiders concluded that Spielberg was not an easy person to work with on the features side (his TV operation has long been headed by Daryl Frank and Justin Falvey).
