Physically stalking as opposed to Instagram stalking, which was kind of great. Leila [from Fifty Shades Darker ] puts my Insta stalking into perspective.

I think working in the industry, I'd be pretty nervous to have a celebrity crush. I'd be pretty nervous if my boyfriend did as well because inevitably you'd end up working with them and then it would feel very suspicious.

I did dancing and singing when I was little, and then when I was 12 years old my friends were taking speech and drama at school. They were private lessons, and I started doing that. Over the years everyone else dropped out and I just kept going. I loved it.

I'm just a psycho myself. I loved playing Leila [from Fifty Shades Darker], taking on [a character] who's completely unhinged. I saw her as a girl who's grief-stricken and she just doesn't have the tools to cope. Grief and heartbreak, it makes you do some pretty crazy things.

I have a bit of a lava lamp fetish. They are kind of hideous, but there is something so therapeutic about them.
