Zoë Kravitz
Kravitz knew she had big claws to fill as the iconic cat burglar. “I got stronger than I’ve ever been,” she’s said of her intense training process, during which she exercised for three hours a day (after being on set for 12 hours!) and learned to fight like a superhero. “I would be so sore because I would do drills and kicks and kicks and kicks for hours,” explained the 33-year-old star of The Batman. “Being able to kick gracefully and remain balanced while maintaining the proper form and having it all look good on camera — that was definitely the biggest thing.”
