Viv's putting her movie star genes to work! Brad Pitt and Angelina Jolie's adorable 5-year-old daughter Vivienne Pitt is a natural as young Princess Aurora beside her famous mom in new stills released from the upcoming Disney thriller Maleficent.In one pic, Vivienne, who was 4-years-old at the time of filming, gives Jolie's "Mistress of All Evil" character an inquisitive stare while wearing a buttercup yellow dress.Jolie, 38, dressed in Maleficent's terrifying all-black costume (complete with terrifying horns!), looks down at her youngest daughter with an evil glare, while Viv nervously twiddles her fingers in response. The blue-eyed, blonde-haired little one strikes a remarkable resemblance to her dad in the still."It had to be Viv," Jolie recently told Entertainment Weekly of why her daughter was cast in the young Sleeping Beauty role. (Elle Fanning plays the grown-up version of Aurora in the movie, opposite newcomer Brenton Thwaites as the dashing Prince Phillip.) "We think it's fun for our kids to have cameos and join us on set, but not to be actors. That's not our goal for Brad and I at all." "The other 3-and 4-year-old [actors] wouldn't come near me," Jolie continued. "It had to be a child that liked me and wasn't afraid of my horns and my eyes and my claws." Indeed, as seen in the photos, Jolie is terrifying as Maleficent, with her blood red lips, a black cape, and elaborate horned headdress.Jolie confessed that the costume even scared her five other kids -- Maddox, 12, Pax, 10, Zahara, 9, Shiloh, 7, and Vivienne's twin brother Knox. "When Pax saw me for the first time, he ran away and got upset," she told EW.Luckily, Pax overcame his fear and even has a cameo with Zahara in the movie. "I had to walk by them being very mean," Jolie recalled of the terrifying scene where she places a curse on newborn baby Aurora. "Of course, I wanted to stop and wink at them." Maleficent, due out May 30, tells the classic tale of Sleeping Beauty from the perspective of the titular villainess.
