Idris Elba’s Unscripted Reactions Turn A House of Dynamite’s Finale Into Edge-of-Your-Seat Tension
A House of Dynamite hurls viewers into the chaos of real-time global crisis control — and Idris Elba says the jaw-dropping finale wasn’t scripted. With Kathryn Bigelow directing and Rebecca Ferguson and Gabriel Basso alongside Elba, the urgency feels scarily real.
Idris Elba and Kathryn Bigelow made a nuclear-crisis thriller that feels alarmingly close to real life, and then they ended it on a note that has people debating in group chats. The wild part: Elba says the final beats weren’t even scripted. That explains a lot about why the climax hits like it does — and why some viewers are not thrilled.

The ending that wasn’t planned
Elba plays the U.S. President staring down an incoming nuclear missile, and the pressure in those final minutes feels uncomfortably real. In an interview with ScreenRant, he revealed the conclusion wasn’t on the page. Translation: some of the reactions you’re watching are Elba responding in the moment, not dutifully following a line reading.
"It wasn’t scripted."
That off-the-cuff approach absolutely sells the chaos of decision-making at the top. It also feeds the backlash from people who wanted a concrete answer about what happens.
What the cast says about the ambiguous ending
Rebecca Ferguson (Olivia Walker) is very much pro-ambiguity. Speaking with ScreenRant, she pointed out the film isn’t out to make one country the villain. The bigger culprit is the unstable logic of nuclear deterrence itself. Her take: you’ve got elite professionals on every side trying to make the least-wrong call, the same impossible math the President is doing in the bunker.
Jared Harris called the unresolved finale "the point" — the idea is to spark a conversation rather than tie a bow on it. He even suggested that without that choice, audiences might "shrug off a really intense ride." Whether you agree probably depends on your tolerance for endings that leave you hanging.
Why some viewers are frustrated
The main complaint: the movie refuses to spell out what happens with the missile or the President’s final decision. Some folks have gone as far as calling it the worst ending ever. Others argue the ambiguity is the whole design. One viewer, @Rob___Walker, summed it up on Oct 25, 2025: it’s deliberately frustrating, it makes you think, and whichever call was made was basically unwinnable — a reminder of how insane nuclear war logic is. He even argued that whether the device detonated is almost beside the point; in his view, America "lost" the second the game started.
My read
This is Bigelow leaning into a you-are-there crisis and refusing to break the spell with an easy answer. If you want a clean detonate-or-diffuse resolution, you’ll likely bounce off the ending. If you’re into a pressure-cooker that keeps you in the moment — and lets the dread linger — the choice tracks, especially with Elba improvising through the final stretch. It’s a bold swing that will land as either brilliantly honest or maddeningly non-committal, depending on your taste.
