"We got nobody backing us up here. Nothing."
If things go by the script, that line will soon be spoken by the actor John Krasinski in Michael Bay's movie version of the Sept. 11, 2012, terrorist attack in Benghazi, Libya.
But Hillary Rodham Clinton, who was secretary of state when the United States ambassador to Libya, J. Christopher Stevens, was killed in the assault, may be the one feeling exposed.
Set for release by Paramount Pictures on Jan. 15, Mr. Bay's film — called "13 Hours: The Secret Soldiers of Benghazi" — will land just two weeks before party caucuses in Iowa. For audiences across the country, it recalls the most controversial episode of Mrs. Clinton's tenure as secretary of state, and one her campaign aides have been trying to put behind them, just before the most critical contest in the Democratic presidential contest.
An unabashed action movie, "13 Hours" will focus on the heroics of real-life Central Intelligence Agency security contractors who defied orders, and two of whom died, in an attempt to defend a State Department compound and nearby C.I.A. annex in Benghazi.
Republican critics of Mrs. Clinton have for years tried to tie what they say was her mismanagement at the State Department to the attack, but that argument has largely been relegated to conservative news media, not a mainstream Hollywood blockbuster.
In the new film, Mr. Krasinski, best known for his role in "The Office" television series, plays the contractor Jack Silva, who survived the attack. James Badge Dale, from "World War Z," plays Tyrone S. Woods, another contractor, who did not.
Scenes in the film's trailer align with a draft from late last year of a script by Chuck Hogan, based on a book by Mitchell Zuckoff. In it, Mr. Hogan does not mention Mrs. Clinton, President Obama or almost any other identifiable Washington official.
The film, which is still being edited, is faithful to Mr. Zuckoff's account and strains to avoid political tilt, said people briefed on its progress who spoke on condition of anonymity because of confidentiality strictures.
"While the events have been the subject of continuous heated debate, few have heard or seen the story told from the perspective of these brave men because it has been largely lost amidst the political back and forth," Erwin Stoff, a producer of the film, said in a statement.
