Apple and Pixar CEO Steve Jobs isn’t letting Disney CEO Michael Eisner get the best of him. During a conference call with analysts on Thursday, Jobs referred to Eisner as a “loose cannon” when asked about a dig Eisner took at Pixar last week at a Disney investor conference. Responding to a question about Disney’s own digital movie efforts, Eisner described the computerized human characters created by Pixar as “pretty pathetic” compared with the ones Disney is creating with veteran animator Glen Keane. Jobs said sarcastically: “Our films don’t stack up to ‘Atlantis,’ ‘Emperor’s New Groove’ or ‘Treasure Planet.'” Jobs then made the loose-cannon reference, saying that it explained why Eisner would say such a thing.
