The ten-month-old baby just happened to be visiting the set of "The Curious Case of Benjamin Button," her dad's new movie, when BOTH of the twins hired to individually play a baby scene were having a bad day.
A pinch hitter was needed, and Shiloh was glad to crawl up to the plate. No problem. Brad grabbed his baby daughter and quickly got her dressed in costume. She reportedly played the scenes (the role: Cate Blanchett's character as a baby) like a pro.
There was only one person unhappy with the whole deal: Cate Blanchett. Used to being the center of attention, she was appalled to see a pint-sized someone steal her thunder.
A Spoof reporter who understands baby talk said that, at the end of the day of filming, the new star was overheard demanding her paycheck and her own dressing room. And as Brad wheeled her to the car, Shiloh was ordering up a bottle of orange juice and asking if she could join the Actors' Equity Association.
