The best thing I've learned is, if you're going out, never go out alone - you leave yourself vulnerable. If you've got someone else there you trust, they can say, be wary of that person. I probably used to be too trusting of people.

I'm 5-foot-5, and I'll wear a big parka and put the hood up, and nobody gives me a second glance.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

I feel like my evolution has come to a place where now I'm attached to Crazy Rich Asians.

I always feel that if you put me in a room with a director and a writer and let me talk about the script, I can give a good account of myself.

I'm certainly lucky to have got famous through something that was so well liked, generally speaking.

I would like to initiate an initiative - the Broadway Annoying Audience Member Relocation Programme.
