What's the most difficult movie scene a child actor has ever done?

 In the film, Maleficent starring Angelina Jolie, you will find her little 5-year-old daughter, Vivienne in the cast too. However, Vivienne wasn’t a planned casting in the film, but rather a forced one because nobody else could do what Vivienne did.

In the movie, Maleficent, Angelina Jolie played the role of a fierce and vindictive protector who puts on an evil appearance. Angelina Jolie, playing the role of Maleficent wears prosthetic cheekbones and horns to play Sleeping Beauty’s nemesis and therefore, looks quite scary. There were some scenes that required a small child, Aurora to play a small appearance with Jolie. However, she looked so scary that none of the small children who auditioned to play the role would stay anywhere near her. Every small child brought to the set was terrified of Angelina Jolie’s costume.

It was only her real daughter, Vivienne Jolie-Pitt, aged 5 years at that time, who was not terrified of her costume because she knew it was her mother. The scene also requires the child to be affectionate towards Maleficent and not get terrified of her. So it was an unplanned casting member, her own daughter, who ended up shooting the scene.
