Oscar winning Director Kathryn Bigelow wants her movie, “A House of Dynamite,” to sound the alarm on the dangers of nuclear weapons.

The tense political thriller, which premieres on Tuesday at Venice Film Fest and stars Idris Elba and Rebecca Ferguson, follows White House officials who scramble to deal with an incoming missile attack on the U.S.

“Hopefully the film is an invitation to decide what to do about all these weapons,” Bigelow said at Venice during the official press conference. “My answer would be to initiate a reduction in the nuclear stockpile. How is annihilating the world a good defensive measure?”

In A House of Dynamite, Elba portrays the president as he’s making an unthinkable decision during dire circumstances while Ferguson plays a senior White House official who has to keep the government running amid the chaos.

Screenwriter Noah Oppenheim wants the story to reflect “the reality of our world since the dawn of nuclear age.” Although the threat of nuclear conflict has intensified in recent years, he adds that “precise geopolitical dynamics at any given time are not really the point” of the film.
