“There’s something about looking into someone else’s makeup bag—it’s such an intimate glimpse into their personality somehow. When I was a kid and working on Harry Potter, I would always ask the makeup artists, or just anyone, ‘Can I see your makeup bag?’ I loved exploring that way. And my other favorite thing was, while I was having my hair and makeup done, to clean and organize people’s makeup bags. So I would sit there and clean every product and put it all back together again.
