MEMO TO BRAD PITT

BRAD PITT, PLEASE NOTE: Even though they interacted at first like dad and doting daughter while filming "The Changeling," pouty ANGELINA JOLIE finally butted heads with director CLINT EASTWOOD - blowing off his pointers on how to play a scene! As Hubba-Hubba huffily vamoosed to her trailer, flinty-eyed Dirty Harry made his move: He sat calmly in his director's chair and simply waited, not uttering a word. It took awhile, said My Spywitness...TICK, TOCK, TICK, TOCK...but sure enough, Angie-Baby blinked first! "Clint knew they'd end up doing it his way, and he just wanted to give Angelina the space to accept that he's the boss," said the insider. "Sure enough, she returned to the set, resolved to giving in to Eastwood, and she said: 'He must know what he's doing - he's Clint Eastwood, after all.'" (Strong and silent, Brad, get it?)
