Inferno Movie Review: The Fourth (and, so Far, Last) Robert Langdon Adaptation

Inferno Movie Review: A Visually Striking (but Simplified) Robert Langdon Adaptation

There’s something oddly comforting about seeing Tom Hanks slip back into Robert Langdon’s familiar tweed. By the time Inferno reached the screen in 2016, this was the third film in the Robert Langdon movie series — even though it adapts the fourth book, since The Lost Symbol skipped theaters in favor of a TV series. (Find out more in my TV Series Review for The Lost Symbol.)

Again directed by Ron Howard, Inferno immediately signals that it will be more intense and visually aggressive than its predecessors (which, in my opinion, is a good thing). Langdon is injured, disoriented, and plagued by disturbing visions inspired by Dante’s Inferno. Instead of easing us into the mystery, the film opens with a breathless chase through Florence and a shocking death–a clear statement that this adaptation is more about momentum than contemplation.

If you loved the novel for its puzzles and travel-forward storytelling, the movie feels like an illustrated version of the story…just a little faster, flashier, and packed with sweeping shots of some of Europe’s most iconic cities. It doesn’t capture every philosophical nuance of the book, but for a visually rich thriller night at home, it’s an entertaining ride.

A Faster, More Action-Driven Story

The film follows the core premise of Dan Brown’s novel: Langdon wakes up in a Florence hospital with no memory of how he arrived there, suffering from vivid hallucinations of fire, corpses, and distorted faces — cinematic echoes of Dante’s vision of hell.

Dr. Sienna Brooks helps him escape when an assassin attacks the hospital, and together they uncover a strange device hidden among Langdon’s belongings. The object projects a digitally altered version of Botticelli’s Map of Hell, pointing toward clues left by Bertrand Zobrist, a brilliant but dangerous geneticist obsessed with overpopulation.

From there, the story races through Florence, Venice, and Istanbul, pursued by agents from the World Health Organization, a shadowy private consortium, and figures whose loyalties are deliberately unclear. Compared to the book, the film simplifies motivations and compresses timelines, but it preserves the central tension: a race against time through beautiful, historically layered cities, with the fate of millions potentially already sealed.

Cast and Performances

Tom Hanks feels fully settled into the role of Robert Langdon by this point in the series. Due to the storyline, in this one, his performance leans into vulnerability more than intellectual confidence–the head injury and hallucinations leave Langdon constantly off balance, and Hanks plays that confusion without tipping into melodrama.

Felicity Jones brings a quiet intensity to Dr. Sienna Brooks. While the film can’t fully explore Sienna’s backstory as a child prodigy the way the book does, Jones suggests depth and internal conflict through restraint rather than exposition.

The supporting cast is a standout. Sidse Babett Knudsen gives Elizabeth Sinskey a weary authority, while Irrfan Khan nearly steals the film as the Provost. His dry humor and moral ambiguity add much-needed texture to a story filled with institutions scrambling for control.

Book vs. Movie: Key Differences

The most noticeable change comes right at the beginning. In the novel, Langdon’s awakening in the hospital is slow and disorienting, allowing readers to piece things together alongside him. The film opts instead for an immediate chase sequence, setting a more traditional action-thriller tone (which is good).

The movie also leans heavily into Langdon’s hallucinations, transforming internal confusion into vivid, often unsettling visual sequences. These moments make the film feel more surreal than the book — a choice that works well cinematically, even if it simplifies some of the psychological tension.

The biggest difference, however, is the ending. Without spoiling specifics, the film chooses a more conventional resolution, with a last-minute race to stop catastrophe. The novel’s conclusion is far more morally ambiguous and unsettling, leaving readers to sit with the consequences. In trading the philosophical discomfort for narrative closure, the movie becomes more easy to take in, but maybe a little less thought-provoking.

The Power of Place on Screen

While the film softens many of the book’s ethical debates, it excels at showcasing the locations (one of my favorite things!). Florence, Venice, and Istanbul are not just backdrops–they are integral to the movie’s atmosphere.

Seeing Florence’s skyline, the Duomo, and the Palazzo Vecchio on screen is genuinely thrilling, especially if you’ve walked those streets yourself. Venice is framed as haunting and fragile, with sweeping shots of St. Mark’s Square and the Grand Canal reinforcing the city’s long association with plague and decay.

Istanbul provides the most dramatic setting of all (it is where the climax happens, too). Scenes around Hagia Sophia and the Basilica Cistern lean into scale, shadow, and history, giving the film its most memorable visuals and a sense of global consequence.

Themes and Overall Impressions

The film still gestures toward big ideas — overpopulation, denial, and whether extreme measures can ever be justified — but these themes largely serve as context rather than the driving force. Where the book lingers on moral uncertainty, the movie moves quickly toward resolution.

That doesn’t make Inferno a weak adaptation; it simply means it serves a different purpose. This is a movie designed to entertain, to move, and to immerse viewers visually rather than challenge them philosophically.

I also found it more consistently fast-paced than some earlier Langdon films, which often relied too heavily on extended exposition. Here, momentum is rarely lost.

Final Verdict: Is Inferno Worth Watching?

Taken on its own, Inferno is a solid, visually striking thriller that makes excellent use of its European settings. As an adaptation, it’s more uneven–some changes translate beautifully to the screen, while others flatten the novel’s most unsettling ideas.

My real thoughts:

• Read the book first if you’re interested in the deeper ethical questions, Dante references, and moral ambiguity.
• Watch the movie for the performances, the travel inspiration, and the chance to see Florence, Venice, and Istanbul brought vividly to life.

If you’re planning a themed movie night or book club gathering, Inferno pairs beautifully with Italian wine, Venetian cicchetti, and a good discussion about whether humanity ever really chooses the “right” solution.
