Unprofessional

How she behaved on the Huckabees set, no matter what the director was doing or was not doing (his behavior was just as, if not more, atrocious), shows her to have been highly unprofessional, not only back to him, but also to her co-workers, particularly when she told Dustin Hoffman and Naomi Watts to f uck off. How uncomfortable she made them all with her childish, unending tirade. This is rather curious given her sterling reputation as a consummate professional to this point. I saw the videos of her meltdowns, and they were utterly embarrassing and disgusting. I wonder, is this the onset of senility, or are we being exposed to her characteristic prima donna behavior that has merely never been publicized before??
