The Twilight actress – who was photographed with a cast on her wrist last week – said that she has been taking a beating while shooting fight sequences for the action-adventure movie.
'I got hurt doing a fight scene with dwarves. This ligament pull was really bad. Every day I have bruises all over. It's full-on,' she told The Sun.
The 21-year-old added that she envies the way that her boyfriend and Twilight co-star Robert Pattinson is so relaxed during television appearances.
'He really shines when he's just funny. I've see him on telly and I go, 'Hmmph, you're really good on TV!'' she said.
