Kristen Stewart is throwing away her damsel-in-distress image and taking up arms against the evil queen, Ravenna (Charlize Theron), in "Snow White and the Huntsman." In her sword-wielding debut, Stewart leads the fight to reclaim the kingdom from Ravenna, and with that comes an inspiring call to arms. When the actress spoke to MTV News at the London premiere of the upcoming film, she revealed her concerns about pulling off the speech credibly.

"We saved it until the very last day, actually," she said. "We re-wrote it every single day of the shoot. Me and [director] Rupert [Sanders] had it in our back pocket the entire time. Ultimately, I don't think that it makes a whole lot of sense, but it feels right. Do you know what I mean? It's very up-in-the-air; it's very subjective until the very end. Until some — I don't want to give anything away, but until the very obvious line. It's so Bravehearty. It's crazy, but it's good. It's good."

Judging by the screaming that greeted Stewart when she hit the red carpet, it doesn't seem like her fame is about to die down anytime soon, even with "The Twilight Saga" nearing its end. In fact, the actress said that the fans at the "Snow White" premiere reminded her of past "Twilight" crowds. "It feels very similar actually," she said. "I was expecting it to be — not smaller — just, I didn't think it would be like this."

And even though Stewart has yet to see boyfriend Robert Pattinson in "Cosmopolis," she revealed he's already seen her in action as the revamped Disney princess. "He likes it. He really likes it. It's cool. It's good. I'm really proud of it," she said.

As she should be, since the actress' transformation into a rousing action star makes this film one of the most highly anticipated movies of the summer. So how exactly will she wind down after a successful premiere?

In true Kristen Stewart fashion, the actress replied, "I love what I'm wearing, but I'm going to take this thing off, first off. [I'll] probably get into some jeans."

Audiences can see Stewart don armor and chainmail when "Snow White and the Huntsman" hits theaters June 1.
