Costars said she was easy on the eyes when she turned heads
in a dazzling white wedding dress.
But not everything Kristen Stewart
wore while filming Breaking Dawn
was easy on her
When the Twilight
actress made her vampire transformation for the second part of the saga's final installment – the first of which arrives in theaters Friday – it wasn't the fangs she had to get used to … it was the amber contact lenses all of the vampires wear in the film.
"That is one thing I can't wait to say goodbye to," Stewart, 21, tells MTV News
of the eyewear accessory. "They just kill you. [They give you] dead face."
She says the lenses, which are also worn by onscreen love interest and real-life boyfriend Robert Pattinson
, limited her vision, "so you feel a little bit more closed off."
Sore eyes aside, she was still happy for her character, Bella, to embrace her inner bloodsucker.
"The whole vampire thing – I wasn't excited to be white and all that," she says. "I was really more excited to finally get her there because she wants it so bad."
