Amy Adams, Viggo Mortensen Added To 'On The Road' Cast

Kirsten Dunst and Kristen Stewart also star in the film based on Jack Kerouac's novel.

And the Beat goes on. Two more have joined the cast of director Walter Salles' upcoming adaptation of the Jack Kerouac novel "On the Road," which already counts Garrett Hedlund, Sam Riley, Kirsten Dunst and Kristen Stewart among its stars.

Viggo Mortensen and Amy Adams have signed on to play the husband and wife couple Old Bull Lee and Jane, according to Deadline New York. Sal (Riley) encounters the Lees, both drug abusers, later in the story and, for all their faults, sees in them the sort of connection that he is looking for in his own relationship.

For those who are unfamiliar with the novel, Kerouac's writings are a largely autobiographical account of his journeys around the country, though specific names have been changed. Old Bull Lee and his wife, Jane, are believed to be noted author William S. Burroughs and his common-law wife Joan Vollmer. Burroughs accidentally shot and killed Vollmer in 1951, an incident he initially said stemmed from a William Tell act gone wrong.

Adams will next appear in David O. Russell's "The Fighter" alongside Mark Wahlberg and Christian Bale. And "On the Road" isn't her only project with a connection to counterculture: "Twilight" producer Wyck Godfrey revealed a few weeks ago that she is also attached to star in a Janis Joplin biopic.

For Mortensen, this marks the second "Road" movie in a short period of time. He starred opposite Kodi Smit-McPhee ("Let Me In") in last year's adaptation of the post-apocalyptic Cormac McCarthy novel "The Road." He'll next star with Michael Fassbender and Keira Knightley in director David Cronenberg's "A Dangerous Method" as the famed psychotherapist Sigmund Freud.
