Biggest Movie Flops of All Time: The Largest Box-Office Losses Ranked by Inflation-Adjusted Dollars

$278 million is the biggest movie flop of all time once losses are converted to 2026 dollars — Disney's John Carter, which the studio wrote down for $200 million in 2012. Twelve films make this ranking of the largest inflation-adjusted box-office losses ever recorded, spanning Heaven's Gate in 1980 to Disney's live-action Snow White, which lost $170 million in 2025.

Every figure below comes from studio write-downs, court filings, or trade-press reporting on production budgets, marketing spend, and worldwide box office — then converted to current dollars using approximate U.S. CPI inflation multipliers, a method explained in full further down. Six of the twelve films released since 2022, which means expensive flops aren't a relic of the pre-streaming era; they're getting more frequent, not less.

The Biggest Movie Flops of All Time, Ranked by Inflation-Adjusted Loss

The biggest movie flops of all time, adjusted for inflation, are led by Disney's John Carter (2012) at an estimated $278 million in 2026 dollars, followed by Universal's Battleship (2012) at $243 million and Disney's Strange World (2022) at $225 million. All twelve losses below exceed $140 million once converted to current-year purchasing power.

Nominal loss figures per studio disclosures and trade-press reporting cited throughout this article. Inflation-adjusted column converts each nominal loss to approximate 2026 dollars using Value Add VC's CPI-based estimate; see methodology below.

How We Ranked These

Each film's loss is estimated as production budget plus marketing and distribution spend, minus the studio's actual box-office take — not the full worldwide gross, since theater chains typically keep roughly half of domestic ticket revenue and 60-75% of international revenue. We pulled nominal budget, gross, and loss figures from studio disclosures, court and bankruptcy filings, and trade-press reporting, cross-referencing each against Wikipedia's List of biggest box-office bombs and box-office data from The Numbers. Because studios rarely publish a full profit-and-loss statement for any single title, every nominal loss figure here should be read as a well-sourced estimate rather than an audited number — a caveat Guinness World Records itself makes when it tracks the "largest box office loss" record.

The studio-take assumption matters more than it sounds like it should, because it varies sharply by territory. A rough industry rule of thumb puts the studio's rental at about 50% of domestic ticket revenue, roughly 40% across most international markets, and as little as 25% in China, where quota rules on foreign-film revenue-sharing have historically capped the studio's cut well below the domestic rate. A film that grosses the same $300 million worldwide can produce very different actual studio revenue depending on how that total splits between the US, China, and the rest of the world — one reason two outlets can report meaningfully different loss estimates for the same title using the same box-office number.

To rank flops from different decades on equal footing, we converted each nominal loss to 2026 dollars using approximate U.S. CPI inflation multipliers for the film's release year — roughly 3.85x for 1980, 2.05x for 1995, 1.65x for 2005, 1.42x for 2011, 1.39x for 2012, 1.14x for 2022, 1.10x for 2023, 1.06x for 2024, and 1.03x for 2025. This is our own estimate, not a figure any studio has published, and it's the reason a film like Cutthroat Island — a $105 million nominal loss in 1995 — outranks several 2020s films with larger dollar-figure write-downs: 31 years of inflation adds roughly $110 million to its adjusted total.

Why These Movies Bombed

The specific failure reasons vary, but three patterns repeat across this list. The first is a mismatch between a film's budget and its audience appeal: John Carter cost Disney roughly $350 million all-in for an Edgar Rice Burroughs adaptation with no built-in fanbase and a marketing campaign that never explained what the movie was actually about, while Mars Needs Moms spent $150 million on motion-capture animation for a family film whose uncanny-valley visuals reportedly repelled the children it was aimed at. The second pattern is franchise fatigue meeting production chaos: Variety reported that The Flash arrived after years of delays, reshoots, and star Ezra Miller's off-screen legal troubles, undercutting a DC relaunch Warner Bros. needed to work.

The third pattern is a sequel or reboot that assumed an audience would show up out of brand loyalty alone. Joker: Folie à Deux followed a billion-dollar original that grossed over $1 billion on a $55 million budget, then alienated that same audience with a musical structure and a 31% Rotten Tomatoes score; it grossed just over $207 million worldwide against roughly $300 million in combined production and marketing costs. Indiana Jones and the Dial of Destiny grossed $384 million — a number that would be a hit for most films — yet still lost Disney an estimated $134.2 million once its $387 million production budget is weighed against the studio's actual box-office take, per Forbes' reporting on Disney's internal accounting.

The two oldest films on this list show that budget overruns and studio collapse aren't new problems. Heaven's Gate director Michael Cimino shot in Kalispell, Montana, and reportedly ran so far behind schedule that United Artists' $44 million budget nearly quadrupled from an original $11.6 million estimate before the film even opened; its failure is widely credited with ending United Artists as an independent studio, which Metro-Goldwyn-Mayer folded into MGM/UA the following year. Cutthroat Island, filmed largely in Malta and Thailand for Carolco Pictures, suffered a similar spiral of reshoots and ballooning costs under director Renny Harlin; Carolco filed for bankruptcy in November 1995, six weeks before the film's release, and never produced another movie.

The 2022-2025 Wave: Recent Flops Are Getting More Expensive

Six of the twelve films on this list — Strange World, The Flash, Joker: Folie à Deux, Snow White, Indiana Jones and the Dial of Destiny, and Wish — were released between November 2022 and March 2025. Their nominal losses range from $131 million (Wish) to $197.4 million (Strange World), meaning the floor for a "biggest flop of the year" headline has risen well past $100 million even before adjusting for inflation. Disney's Snow White lost the studio $170 million, according to Forbes' reporting on Disney's February 2026 financial disclosures, on a film that cost between $240 million and $270 million and grossed $205.7 million worldwide.

Wish, released in November 2023, illustrates why a decent worldwide gross doesn't guarantee profitability: the animated film brought in $255 million globally against a $200 million budget, yet Disney's actual revenue share — box-office cut, home entertainment, and licensing combined — landed at $231 million against costs the studio needed closer to $400 million to break even on, producing a $131 million loss. This likely means Disney's internal greenlighting math for mid-budget animated originals, as opposed to established franchises like Frozen or Moana, has gotten more conservative since Wish's underperformance.

What the Ranking Misses

Inflation-adjustment methodology varies meaningfully by source: Guinness World Records calculated Cutthroat Island's loss at $145 million when it still held the record in the early 2010s, while our CPI-based conversion to 2026 dollars puts the same nominal loss at $215 million — both are defensible, but they aren't the same number, and neither is an audited figure released by the studio itself. Older films also carry more uncertainty in their original nominal-loss estimates than recent ones, since 1980s and 1990s trade reporting on studio finances was less standardized than it is today.

Streaming-era releases are also harder to measure by box office alone. A film that debuts theatrically and moves to a subscription service within weeks can still generate meaningful subscriber-retention value that a pure theatrical-loss number doesn't capture, so titles that skip a wide theatrical run entirely don't appear on this list even if a studio privately considers them underperformers. None of the twelve films here fall into that category — all had wide theatrical releases — but it's a real limitation of box-office-loss rankings generally, not a defect specific to this one.
