(CNN)- Casting continues for HBO's upcoming movie "Game Change," based on the bestselling book documenting the contentious 2008 presidential campaign.
Hollywood Reporter writes that the role of Bristol Palin will be played by Melissa Farman, whose resume includes roles in the television series "Lost" and "Law and Order."
Farman joins a star-studded cast of Julianne Moore, Ed Harris, and Woody Harrelson who have already committed to the project.
Harris is onboard as 2008 GOP presidential contender John McCain, Moore is set to play the part of McCain's running-mate Sarah Palin, and Harrelson as McCain's senior advisor and senior strategist, Steve Schmidt.
HBO's adaption of John Heilemann and Mark Halperin's bestseller focuses on McCain's flailing presidential campaign, starting from his decision to pick Palin as his running-mate in the general election.
According to the Hollywood Reporter, CSI's Larry Sullivan is signed on to play Sarah Palin's deputy chief of staff, Chris Edwards, and actor Jamey Sheridan of the NBC series "Trauma," will play part of McCain's senior campaign advisor Mark Salter.
Tom Hanks will be an executive producer on the project.
