I think the thriller aspect of this film [Fifty Shades Darker] is what excited me most.

I first got into acting when I was about 12. I started doing speech and drama lessons. All my friends were doing it at the time and my dad encouraged it. He encouraged any extracurricular activity.

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

There was a girl that bullied me years ago, and I was going through, you know, just the standard Instagram wormhole on her account, going way back into her photos and, yes, ended up liking something and I was like, "No!" I just wanted to disconnect my Instagram - Oh, and then she wrote me a message saying, "It's so great to see you doing well." I was like, "Nope, nope, you don't get to say that now!"

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 think for me, home needs to be a sanctuary. I need to feel like I've escaped the day when I get home.

I think working in the industry, I'd be pretty nervous to have a celebrity crush.
