Julianne Moore as Sarah Palin (HBO/HBO)

Well, on Wednesday, the teeth-gritting began: HBO sent out a video tease that offered a very quick look at Moore’s chameleon-like performance in “Game Change,” based on book of same name, which the pay cable network will debut in March.

In the tease, you also get brief glimpses of Ed Harris playing Sen. McCain, and Woody Harrelson as adviser Steve Schmidt.

“Game Change,” based on Mark Halperin and John Heilemann’s 2010 book about the 2008 elections, follows the Arizona senator’s presidential bid from the time of his selection of then-Alaska Gov. Palin as his running mate to their November defeat.

The project reunites members of the team behind HBO’s flick “Recount,” about the aftermath of the 2000 presidential election. Danny Strong, who wrote “Recount,” wrote the “Game Change” script. “Recount” director Jay Roach, “Recount” director, also directed “Game Change.”

In October, Moore talked about researching for the Palin role:

“[I]n terms of the research I did on the way campaigns are conducted, so much is about how do you get on the air, how do you get the most media attention, how do you make the most noise. When in fact, what we’re all looking for is leadership, we don’t want noise. We want people who are going to take care of us,” she told ABC News.

“Right now, the way I feel is that everybody is so divisive, and so self-interested and so much about being re-elected and special interests that I’m really disgusted. I mean, I really feel kind of ashamed.”

Palin’s suggested — while talking to Hannity about Moore back in March, — that she and other “of these gals who pretend like they are me” for “job security” should be giving Palin some financial remuneration. “[P]erhaps they want to spring for one of my kids’ sets of braces or something as they capitalize on pretending to be me,” she joked to Hannity.

No response so far from Moore.

You may know Moore from her gig playing Nancy Donovan — high school crush of NBC suit Jack Donaghy (Alec Baldwin) — on NBC’s “30 Rock.” Moore also had a co-starring role in the Oscar-nominated flick “The Kids Are All Right.” Moore’s credits also include starring in films such as “A Single Man” and “An Ideal Husband”).
