When the book Game Change came out two years ago, the political-media industrial complex spent a few weeks in a tizzy, with everyone fact-checking the “deep background” scooplets authors Mark Halperin and John Heilemann had dug up while reporting on the 2008 presidential campaign. (Some held up, others were unverifiable.) Which was exactly the sort of book it was: Deep insights into the way American government functions were missing, but there was a ton of good dirt. The authors promptly snapped up a $5 million advance to write a sequel, and HBO picked up the Hollywood rights. Now, most of the gossip in the book has been forgotten, but the movie version—starring Julianne Moore as Sarah Palin—premieres Saturday night. Today, Halperin and Heilemann preview the movie and talk about the 2012 election—but presumably, they’ll save the best stuff for the book.

The authors speak at 2:30 p.m. at the Newseum’s Knight TV Studio, 555 Pennsylvania Ave. NW. Access included in $21.95 museum admission. www.newseum.org. (888) 639-7386.
