Dinesh D'Souza's anti-Hillary Clinton film, "Hillary's America: The Secret History of the Democratic Party," has quickly become the top-grossing documentary of 2016.

D'Souza's doc has brought in $5.2 million in the first 12 days of its release, according to Box Office Mojo.

That puts the political documentary ahead of "A Beautiful Planet," which only grossed $4.1 million this year.

"Hillary's America" also beat out Michael Moore's latest film, "Where to Invade Next," which made $3.8 million, according to the Hollywood Reporter.

D'Souza told FOX411 last week that he hopes both Republicans and Democrats view his film.

“What I am hoping the movie will do is reach well-meaning people in the middle, sincere Democrats who go ‘I can’t believe this,’” he said. “We have had people who have been in the movie, particularly minorities particularly Hispanics and blacks, and they say ‘Dinesh the only question I have to ask you, is this true? Because if they are true it changes everything’. And that’s the thing. The things in my book are movie are true and they cannot really be disputed and it does change everything."
