Juno: I adore Daniel Radcliffe
The Killer Joe actress and the Harry Potter star recently finished filming fantasy horror film Horns, about a boy who wakes up to find he has grown horns with supernatural powers and uses them to avenge his girlfriend's death.
Juno, who has just been nominated for an EE Rising Star Award, said: "Daniel is such a brilliant human being. I am so happy that I have had the opportunity to work with him. He is such a down-to-earth, raw and giving person. I adore him."
And The Dark Knight Rises star fell in love with Canada while filming on location there.
She revealed: "It was amazing for me to because I was filming in Vancouver and I'd never been, and the trees, the forests there are extraordinary. Also, randomly, truly the best sushi I have ever had."
She said: "That job was fantastic - it was all new for me because it was motion capture, so you were in those suits with little bobbles, so you feel like you've been in a video game."
The London-born actress admitted she misses home, but moving to Hollywood was a must for her.
She said: "I miss home, I miss my family and my friends here. But Hollywood - they make movies on every corner, they make movies all the time, there's so much work on offer.
I'm having a good time out there and it's the same with any city, as long as you surround yourself by good people, you're having a good time."
