Kristen Stewart will be traveling On the Road with some high-profile company. The Twilight beauty, who’s currently filming the movie adaptation of Jack Kerouac‘s classic novel in Canada, has just been joined by two new co-stars. (Sadly, no, neither of them are named Robert Pattinson—though her Twilight co-star did pay Stewart a sexy visit on set yesterday.)

The Lord of the Rings star Viggo Mortensen and Enchanted actress Amy Adams have both signed on for the Walter Salles-directed adaptation, which is slated for release next year. Mortensen will portray Old Bull Lee, a character inspired by Naked Lunch author William S. Burroughs, while Adams will play Jane, based on Burroughs’ wife, Joan Vollmer. (Vollmer died in 1951 at the age of 28 when Burroughs accidentally shot her in the head. Apparently Adams, who has also signed on to play rock legend/drug casualty Janis Joplin, has acquired a taste for playing ill-fated historical figures.)

Stewart is portraying Marylou, based on LuAnne Henderson, the first wife of Neal Cassady (dubbed Dean Moriarty in the book/movie, and portrayed by Garrett Hedlund).
