Millie Bobby Brown waves quickly to the cameras while arriving to her hotel in London, England on Tuesday morning (May 28).

The 15-year-old actress kept it chic in an Antonio Berardi look as she continued promo for her new movie, Godzilla: King of The Monsters.

“I physically trained for this role,” Millie shared in a new interview about her debut film role. “When you watch the movie you see I have a lot of running. Running takes its toll. Especially if I was running up the hill and didn’t want to be out of breath when I got to the top and had to say lines.”

She added that she, like her character, wasn’t a fan of Godzilla.

“My character isn’t [either],” she pointed out. “She’s just a teenage girl learning about the Titans as she goes along. I think her love and affection for him grow in the movie.”

Godzilla: King of Monsters hits theaters on Friday, May 31st.
