John J. Nicoletti is exiting as VP of Global Communications for The Walt Disney Studios and returning to flack for the Walt Disney Parks And Resorts. He'll be replaced by Paul Roeder, a Walt Disney Studios publicist and disciple of chief Disney PR woman Zenia Mucha.An insider tells Deadline that Nicoletti was out of his league at the Studios. He seems like a genuinely nice person, but was never a good fit for the job.
