Kristen Stewart feels huge pressure from 'Twilight' fans and worries about being 'persecuted' if she doesn't get her character right.

The 20-year-old actress, who plays Bella Swan in the movie series opposite rumoured boyfriend Robert Pattinson, admits she worries about what people think of her interpretation of the much loved character, who first appeared in Stephenie Meyer's books of the same name, reports femalefirst.co.uk.

'It's just surreal to be a crucial part of a machine like this. I'm sort of the vessel. I feel if I am not laying the character right, I would be persecuted and put on a cross,' said Stewart.
