Zendaya was afraid of peeing or shitting herself while filming Dune: Part Two

Still, she had to learn the hard way what the character she played in Dune: Part Two has known her whole life: in the desert, water is everything. “We were in Jordan. It was very hot, and I remember thinking, ‘Oh, man, the bathrooms are so far away,’ because we had to hike to the locations. If you have to pee, you need at least 10 minutes to get out of the costumes. I was like, Damn, I don’t want to drink too much water,” the actor recalled during an interview with W Magazine. “I had such a fear of peeing myself or shitting myself, honestly, in the suit on set.”

While it’s a pretty funny prospect, the actor soon found herself in a far more serious situation. “One day, I didn’t drink enough and I had a heatstroke. I felt so barfy,” she continued. “I remember calling my mom on the bathroom floor, saying, ‘I feel terrible.’ She was like, ‘Did you drink water today?’ I said no. I thought I was being smart, but you can’t do that. So, lesson learned.”

In addition to posing some potential bathroom challenges, the suits were also “very heavy and restrictive,” Zendaya explained. Luckily, she had just come from weeks of training for Challengers, so “when I was walking through the sand every day, my butt looked great. So that worked out!” Ahh, the glamour of Hollywood.
