Like husband, like wife. On Saturday, August 10, Angelina Jolie followed in the footsteps of Brad Pitt, who made a number of surprise visits across the country to promote "World War Z", as she sent fans at Disney's D23 expo into frenzy with her unannounced appearance to promote her upcoming film, "Maleficent".

Maleficent is the main antagonist in Walt Disney's 1959 film "Sleeping Beauty". Reminiscing about the horns she had to wear as the villain on set, Jolie said, "I miss them. I love them." To the audience, the "Salt" actress shared funny story of how she scared little kids while in costume.

"The strange thing was, people with little kids would visit the set, and I would think, 'I'm a Disney character,' " Jolie said to laughter. "And I would go over to the children ... and they'd scream and run off. One little kid even said, 'Mommy, please tell the mean witch to stop talking to me.' I guess we did a good job."

However, there was one little girl who was not afraid of her imposing character at all. "Vivienne was the only 4-year-old who wouldn't scream," she revealed, referring to her daughter who makes her acting debut in the Robert Stromberg-directed pic, playing Young Aurora.

Jolie, rocking an all-black ensemble during the presentation, was there to unveil clips from the movie. She additionally revealed that Maleficent was "always my favorite." She explained, "I was terrified of her, but I was so drawn to her ... She had this elegance and grace, and yet she was so cruel."

Juno Temple, Elle Fanning, Sharlto Copley and more co-star in "Maleficent", due out July 2, 2014 in the U.S.
