'Game Change' Sees Julianne Moore 'Accurate' as Sarah Palin

Actress Julianne Moore has portrayed Sarah Palin in HBO's docudrama "Game Change" so accurately that Palin's former adviser felt uncomfortable viewing it.

While Palin has disparaged the drama as a "false narrative," one of her top advisers said the film was "true enough to make a squirm."

Nicolle Wallace served the 2008 Republican Vice Presidential candidate during the campaign and was one of Palin's main handlers during the events four years ago.

"This is a movie about the vast gray area where 99 percent of our politics actually takes place," explained Wallace while on "This Week" on Monday. "You're just feeling your way through a gray area and doing your best and that campaign was one of those instances for me."

Since the 2008 campaign, Wallace and Palin have had a public clash of opinions resulting in a feud. In an interview last year, Wallace revealed that the mentally ill character in her fictional book "It's Classified" was based off of Palin.

Wallace explained to ABC News that Palin "seemed deeply troubled" at times during the campaign, and that the candidate's behaviors "concerned me."

"They concerned a lot of people," said Wallace in the October interview. "We did have discussions about whether it would be appropriate from someone who seemed to swing from so high to so low, when the pressure of the campaign was placed on her shoulders, would it be appropriate for somebody like that to have to endure the burdens of the vice presidency?"

In "Game Change," Wallace is portrayed by Sarah Paulson. Palin is portrayed by Oscar-winning actress Julianne Moore. The 51-year-old actress discussed her work in the film.

"It's really a daunting task to play somebody who is not only a living figure, but a hugely well-known one," said Moore speaking to San Jose Mercury News. "For me, the most important thing was accuracy. I wanted to be as accurate as possible."

Palin and her aides have condemned "Game Change," and the former Alaska governor even said she will not watch it.

"I believe my family has the right priorities and knows what really matters," Palin told ABC News in an email. "For instance, our son called from Afghanistan yesterday and he sounded good, and that's what matters. Being in the good graces of Hollywood's 'Team Obama' isn't top of my list."

The HBO film is 118 minutes-long and also stars Woody Harrelson and Ed Harris.
