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 usually have a drink before a carpet because I find them really nerve-racking. Usually a tequila. An upper!

Particularly on social media, there is that level of detachment, some people feel like they can say whatever pops in their head .

All the photographers were trying to just get me off, which was hilarious. But it was very, very amusing.

I kind of liked all the creeping stuff [in Fifty Shades Darker], like when they're sleeping and there's me just standing behind the bed. It was great.

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

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.
