The Perks of Being a Wallflower star Emma Watson has revealed that she was advised to quit acting by a university professor.

The 23-year-old Bling Ring actress also described how she was affected by the media hype, which claimed that her career would be over after Harry Potter.

Watson told Entertainment Weekly: "For a while I kind of bought into the hype of, 'Will they ever be able to play anything else?'.

"It gave me a sense of paralysis and stage fright for a while. And then a professor told me that they didn't think I should act, either. So I was really grappling with it and wasn't feeling good about it.

"And then, I don't know... it got so bad and people had put me in a box so much that it started ******* me off. I suddenly wanted to prove them wrong. It gave me fuel, in a way. I'm not sure why that shift happened."

However, Watson said that reading the script for The Perks of Being a Wallflower made her realise that acting was what she wanted to do.

"Falling in love with that and then having such a great experience on that movie kind of sealed the deal for me," she said. "I stopped intellectualising it, and it became much more instinctual.

"I just got the bug and got very driven all of a sudden, which I really wasn't before. But I'm so happy. It's all felt very new to me, really."
