Michelle Pfeiffer reveals what happened when she saw Angelina Jolie in full 'Maleficent' wardrobe for the 1st time

The actress also gave advice to the new Catwoman.

Michelle Pfeiffer is shaking things up on the silver screen as Disney's newest formidable queen in the "Maleficent" sequel.

The Academy Award-nominated actress told "Good Morning America" that "it was a lot of fun" to play the villainous Queen Ingrith.

"She is the Queen of Ulstead and she is somewhat damaged and proves to be a worthy adversary of Maleficent and we come face-to-face," she explained of her character. "I am also the future mother in law of Aurora," who is played by Elle Fanning.

Pfeiffer said that she had only seen Jolie in rehearsal where "everybody's sort of half done," but was stunned when they shot their first scene together in full hair, makeup, prosthetics, wigs and wardrobe.

"I hadn't really seen her fully in all of her glory and it was the scene where my character actually sees her for the first time and the doors open and there she is and it's stunning," Pfeiffer recalled, adding that it took her breath away. "I just thought, 'Imagine this walking into your dining room.' So I didn't really have to act much."

The actress well-known for her role as Catwoman in the 1992 hit "Batman Returns," said it's one of her favorites and offered a piece of advice for Zoe Kravitz who will be the next actress to put on the catsuit.

"Make sure whilst designing the costume they consider how you're going to go to the bathroom," Pfieffer said candidly. "Minor detail -- it's an important one."

"Maleficent: Mistress of Evil" is in theaters nationwide Oct. 18.

Disney is the parent company of ABC News.
