Talking to omg! at the London premiere of the film, Kristen Stewart explained that aside from the painful red contact lenses, she enjoyed getting in touch with her inner vampire.
She said: "The contacts are definitely a nightmare. The rest of it wasn't so bad.
"I couldn't wait. It had been years playing her [Bella Swan] as human. I didn't feel like I was jumping into this fantasy world it just felt like the next step, the next natural progression for her."
