EXCLUSIVE: A decade after his standout performance in HBO’s miniseries Band of Brothers, Ron Livingston is back at the pay cable network with a co-starring role in the film Game Change, produced by Tom Hanks and Gary Goetzman’s Playtone. The movie, directed by Jay Roach, follows John McCain’s (Ed Harris) 2008 presidential campaign, from his selection of Alaska Gov. Sarah Palin (Julianne Moore) as his running mate to their ultimate defeat in the general election. Livingston, repped by UTA and Thruline, will play Mark Wallace, a senior adviser to McCain-Palin 2008. He led the debate-preparation team for Gov. Palin, who ended up exceeding expectations in her face-off with Joe Biden.

Kelli Giddish, star of NBC/Jerry Bruckheimer’s freshman action drama Chase, is changing the pace with an arc on CBS’ praised legal drama The Good Wife. Giddish will appear in the last two episodes of the season playing what is described as a provocative role — an investigator for Lockhart Gardner who used to work with Kalinda (Archie Panjabi). There is a possibility for Giddish, repped by Paradigm and Invictus, to return in the fall, though The Good Wifeis yet to be officially renewed, so the show’s producers have not started working on storylines for Season 3.
