Emma Watson has revealed that she prepared for her Bling Ring role by watching "a ton of reality TV".
The former Harry Potter star plays Nicki, the pole-dancing 'Valley vixen' of the notorious Hollywood Bling Ring, a group of teens who reportedly stole from celebrity homes in 2008 and 2009, in Sofia Coppola's film.
"I was doing an English course. So I would go from reading Virginia Woolf to [watching] Kim Kardashian. I kind of loved it, this mix of super-high and super-low culture," she told the UK edition of GQ magazine.
The Perks Of Being A Wallflower actress admitted she hates her character - but chose to take the role so she wouldn't be typecast.
"When I read the script and I realised that essentially it was a meditation on fame and what it's become to our society, I had to do it. The character is everything that I felt strongly against - she's superficial, materialistic, vain, amoral. She's all of these things and I realised that I hated her," she said.
The 22-year-old added: "How do you play someone you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be."
Emma - who is dressed up as Nicki on the magazine's May cover - said that she wanted to avoid being pigeonholed in period dramas or "Harry Potter"-like films.
"I was open-minded about doing anything, but the one thing I didn't want to do was get myself into a corset because I was worried I'd never get out again," she said.
"I knew it would be a really comfortable thing to do, but I felt.... I had to dive into something really different. This has been a really big departure for me; it's a really big character."
