Angelina Jolie's daughter Shiloh found the idea of playing a princess in 'Maleficent' "very funny".
The actress initially offered the part of young Aurora to the seven-year-old tomboy, but the youngster thought the idea of playing a princess was "very funny", so it went to her five-year-old sister Vivienne instead.
Angelina said: "We knew she would [say no]. We mentioned the idea of playing a princess and she obviously thought it was very funny. She's not that kind of girl."
Angelina - who also raises sons Maddox, 12, Pax, 10, and Vivienne's twin Knox, as well as daughter Zahara, nine, with fiance Brad Pitt - was delighted at how easily her youngest girl adjusted to being on camera.
She told 'Access Hollywood': "That's just Vivienne. We call her my shadow. She's a very... she's wonderfully affectionate, very much a mommy's girl and so it was a natural fit. It was very easy and very fun to do."
Meanwhile, Angelina's co-star Sam Riley has revealed his 90-year-old grandfather is one of the actress' biggest fans.
He told E! News: "It was my grandfather's 90th birthday while we were shooting and they changed the schedule so I could go home.
"She signed him a birthday card, which is pride of place in the kitchen. He shows it to everybody who comes around."
And the brunette beauty also impressed the actor's parents.
He added: "When my mom and dad came to visit she was so lovely with them that they floated back home. They're still telling everyone."
