Zoe Kravitz has opened up about playing a girl with an eating disorder in her new indie flick The Road Within saying she was "lightheaded all the time".
26-year-old Kravitz, who is the daughter of Lenny Kravitz and Lisa Bonet, told Nylon magazine, "I struggled with an eating disorder in high school and into my early 20s.
"That's part of what actually attracted me to the role; I think it's really important to talk about body image and the struggles a lot of women have with food - especially in the entertainment industry. I related to her in a lot of ways."
The star dropped 20 pounds ahead of filming and added, "Losing all the weight - I've never done anything like that before. I put my body through so much and at first it was really hard to even have a conversation because I was so lightheaded all the time. On top of just being tired, I had to try and perform, so it was very unique experience.
"I lost like 20 pounds, so I was 90 pounds while we filmed. I tried to do it in a healthy way, but it's not a healthy thing to do - I would never tell anyone to lose that amount of weight and especially not that quickly."
Kravitz previously told Complex magazine of the effect the role had on her mental state, "It was f***ed up, man. You could see my ribcage. I was just trying to lose more weight for the film, but I couldn't see, 'You're there. Stop.' It was scary."
The film also stars Robert Sheehan as a young man with Tourette's Syndrome and we caught up with him while he was in Dublin for the JDIFF premiere of the film.
