Kristen Stewart has done accents before. You need to look no further than the blockbuster big-screen adaptation of "Snow White and the Huntsman" for a prime example. But creating Marylou for the big screen version of Jack Kerouac's "On the Road" was a completely different kind of experience. It wasn't really just about the way she sounds when she speaks, but also about what's embodied in every word she says.

So, when Stewart and the rest of the crew sat down to study up on the film, they were treated to audio recording of Lu Anne Henderson, the woman that Kerouac had based his "On the Road" character on. From there, she began to come to life.

"It's funny. For one thing, it's in 1948, and people spoke with a very different canter, literally it is like an accent. And [we] had listened to these tapes of hers and I think it took five minutes for everyone to sort of look around the table and just start laughing cause no one really knew how to handle how infectious it was," she told MTV News on Thursday (December 13) at a junket for the December 21 release.

And, Stewart really had to adopt the speech pattern of Marylou, who she explains sounds nothing like her. She added, "It was like suddenly everyone just completely fell in love with her, the way her voice sort of ... it's really melodic. It goes up and down and is everywhere incredibly expressive, whereas I do speak in a very monotone sort of way. Even though she grew up in L.A. and then moved to Denver, she just sounded like she was from a different world."

Moviegoers will be transported to another world when they go to the Walter Salles-directed flick, which co-stars Sam Riley and Garrett Hedlund as the story's main fellas, Sal Paradise and Dean Moriarty, respectively. The film takes place in the late 40's as those dudes, along with Marylou and a colorful cast of characters, embark on a journey in a time before words like "LOL" and "NSFW" had made it into the English-speaking vernacular.

"The one thing that struck me was they just used more words to describe what they spoke about, but I didn't find myself saying words like 'swell'," she said, but did note she took something away from the flick. "And there is one thing that she said constantly that I tried to adopt actually and by the end of it did, I could naturally kind of own it. But she was constantly going 'in any case' 'cause she was constantly in one direction and another, just constantly talking about a million different things. After everything she said it was 'in any case.' It was really cute."
