The writer behind the 2012 HBO film “Game Change” claims Sarah Palin is to blame for his very first gray hair.

Danny Strong tells The Hollywood Reporter that ahead of the premiere of the premium channel’s Julianne Moore-starring flick — based on the book of the same name by Mark Halperin and John Heileman that gives a behind-the-scenes account of the 2008 White House race — the former GOP vice presidential candidate’s camp blasted the film.

“Her aides came out guns blazing and attacked us a week before the movie came out. And they said, ‘We haven’t seen the movie, but it’s all lies.’ ”

Strong, who also wrote the screenplays for “Recount” and “The Butler,” told the publication with a laugh, “And I remember about a week or two after that ended, I saw that I got my first gray hair. And I thought, ‘Sarah Palin gave me gray hair.’ ”
