In a new interview with Hero Complex, Evanna Lynch talks about playing Luna Lovegood and being in the Harry Potter films.  Some segments from the interview may be read below.

“I just felt that if anyone was to play her, it should be me,” Lynch said. “It was like studying for a math exam. I studied to be her. I really, really like her. I think that parts of me are like [Luna], but I am different. I had to be in the audition. I said ‘I know that you may have ideas of who Luna is, but here is how I see her.’ “

In “Deathly Hallows,” Luna’s famously positive attitude and demeanor is tested, but she remains steadfast in her optimism and detached calmness even while  imprisoned  in the dungeon-like gloom of the Malfoy Mansion basement.  ”I don’t think Luna changes. The thing about her is that she’s so relaxed about herself. She has to be a bit more serious than normal [in “Deathly Hallows”] and has to accept that times are dark. She always sees the positive and has a spirituality about herself. She doesn’t think that death is the end.”
