(CBS) New cast members have been announced for HBO's adaptation of "Game Change."

Actors Melissa Farman, Larry Sullivan and Jamey Sheridan will join the political telefilm about the 2008 presidential election.

Pictures: Julianne Moore

According to The Hollywood Reporter, Farman, who also appeared in "Temple Grandin," will play Sarah Palin's daughter Bristol, while "CSI" actor Sullivan has been cast as Palin's deputy chief of staff Chris Edwards. Sheridan (from "Law & Order: Criminal Intent") will play the role of John McCain's speechwriter and senior campaign advisor Mark Salter.

Back in March, HBO announced that Julianne Moore will play Palin. Ed Harris will perform alongside her as McCain.

"Game Change" is based on John Heilemann and Mark Halperin's bestselling book. It will be directed by Jay Roach and written by Danny Strong, who previously teamed up for HBO's Emmy-winning election-themed film "Recount."
