Risch, who co-starred with Other Desert Cities leading lady Stockard Channing in the Broadway revival of Pal Joey, covers for Tony Award nominee Thomas Saodski, who is on leave from the production to film the new Aaron Sorkin HBO series "The Newsroom." Risch will appear through Dec. 25.

As previously reported, Sadoski will return to Other Desert Cities for two weeks beginning Dec. 27 to conclude his run on Jan. 8, 2012. He will be replaced by "Weeds" and "Angels in America" star Justin Kirk beginning Jan. 10, 2012.

The cast of Other Desert Cities also features Tony Award winner Channing (Six Degrees of Separation, The House of Blue Leaves) as matriarch Polly Wyeth, Golden Globe winner Stacy Keach (Indians, "Hemingway") as Lyman Wyeth, Tony nominee Judith Light (Lombardi, "Ugly Betty") as Silda Grauman and Rachel Griffiths ("Brothers & Sisters") in her Broadway debut as Brooke Wyeth.

Here's how LCT bills the play: "In Other Desert Cities Brooke Wyeth (Griffiths), a once promising novelist, returns home after a six year absence to celebrate Christmas in Palm Springs with her parents, former members of the Reagan inner-circle (Channing and Keach), her brother (Sadoski) and her aunt (Light). When Brooke announces that she is about to publish a memoir focusing on an explosive chapter in the family’s history, the holiday reunion is thrown into turmoil and the Wyeths are both bound together and torn apart as they struggle to come to terms with their past."
