Make it two in a row for The Expendables 2.

Sylvester Stallone's action flick was the box office champ for the second consecutive weekend, earning an estimated 13.5 million dollars.

Of the new releases, the Joseph Gordon-Levitt thriller Premium Rush made the most money: 6.3 million. However, the anti-Obama documentary 2016: Obama's America, which expanded into wide release, collected 6.2 million in less than half as many theaters.

Box office analyst Paul Dergarabedian says the success of 2016 is unusual. He says, "This is unheard of because typically the big documentaries that are political that do well are usually liberal-based or have liberal themes or are liberal-minded."

The Dax Shepard-Kristen Bell comedy Hit and Run opened in 10th place, with 4.7 million, and the horror film The Apparition debuted in 12th place, with three million dollars.

Here are the top 10 movies from Friday, August 24th, through Sunday, August 26th, with estimated ticket sales:

1. The Expendables 2, $13.5 million.
2. The Bourne Legacy, $9.3 million.
