The film industry revolves around massive investments, yet studios and backers often become so engrossed in a captivating idea, a high-profile director, a leading star, or visions of enormous profits that they neglect the foundational elements of filmmaking. In many cases, the screenplay is treated as an afterthought, with incomplete, rough, or entirely absent scripts becoming the norm for major productions. Despite this, these films managed to achieve financial success. Here are 10 notable Hollywood movies that moved forward without a finalized script.
10. Jaws (1975)
Jaws revolutionized cinema in the 1970s, transforming a novice director, a modest budget, and numerous production challenges into a monumental box office success. It also established the blueprint for the modern summer blockbuster. Steven Spielberg’s shark-centric horror thriller remains a landmark in film history, frequently appearing on global Top 100 lists and continuing to influence filmmakers worldwide.
However, the production felt more like an extravagant student film, lacking a proper script or a clear vision, all while being shot on the unpredictable open ocean.
Richard Dreyfuss, who played oceanographer Matt Hooper, revealed that the film began production without a script, a finalized cast, or a working mechanical shark—the central antagonist. It was Steven Spielberg’s innovative vision and technical expertise, combined with a budget overrun of approximately $10 million, that ultimately saved the project and turned it into a success.
9. Boyhood (2014)
Director Richard Linklater has always embraced challenges, frequently experimenting with genres and pioneering new filmmaking methods, often achieving remarkable results. When the idea for Boyhood emerged—a project filmed over 12 years—he eagerly took on the ambitious endeavor.
Linklater’s Boyhood captures the full spectrum of adolescence, filming with young actor Ellar Coltrane annually over the 12-year span. The project’s organic approach allowed the story to evolve based on the actors’ real-life experiences, with only a loose framework guiding the narrative. This unconventional method meant no formal script was used, relying instead on the natural progression of the cast’s lives.
As Linklater explained, he collaborated closely with Ethan Hawke, Patricia Arquette, and the young actors, including Coltrane and his daughter Lorelei. As they grew older, their contributions became even more integral to the process. The film, a heartfelt passion project, defied its indie roots by earning over ten times its budget at the box office.
8. Alien 3 (1992)
The Alien series remains a powerhouse 45 years after Ridley Scott’s groundbreaking sci-fi horror debut. However, its journey hasn’t been without challenges. In the early 1990s, after the success of James Cameron’s Aliens, producers David Giler and Walter Hill aimed to leverage the franchise’s enduring appeal with Alien 3.
Pre-production was chaotic, with multiple scripts and directors being replaced and $7 million spent before filming even began. To regain control, 20th Century Fox brought in newcomer David Fincher. Despite efforts to manage the rookie director and curb escalating costs, the production faced a critical issue: there was no finalized script.
The turmoil before Fincher’s involvement left the team with a patchwork of incomplete drafts from various scripts, which they decided to use regardless. This led to a notorious clash between Fincher, the producers, and the studio. Although Alien 3 remains a polarizing entry, it performed well enough to sustain the franchise and set the stage for future installments.
7. Men in Black 3 (2012)
Fans of Men in Black endured a ten-year wait for the return of Agents J (Will Smith) and K (Tommy Lee Jones) after the franchise’s second installment faced a troubled production and harsh criticism. However, hopes were reignited in 2009 when a third film was announced, with Smith and Jones confirmed to reprise their roles, signaling a promising new chapter.
Sony rushed into filming Men in Black 3 in November 2010 to capitalize on the availability of its key players—Smith, Jones, and director Barry Sonnenfeld—and to secure a significant tax incentive from New York State. This urgency, however, meant the production began without a finalized storyline, essentially shooting without a clear plot.
With only one act of the script completed, the team pressed forward despite ongoing disputes among producers, writers, and cast members about the film’s direction. Unsurprisingly, by the time MIB 3 reached completion, its production costs had ballooned to approximately $220 million.
6. Jurassic Park III (2001)
Before Jurassic World: Dominion in 2022, Jurassic Park III was widely considered the weakest entry in the Jurassic series. As the first film not adapted from Michael Crichton’s novels, it faced the daunting task of matching the success of its predecessors. This challenge was compounded by the absence of Steven Spielberg, a mostly new cast (save for Sam Neill), and the lack of a completed script.
Initially, director Joe Johnston and a team of writers completed two versions of the script, which were storyboarded and scheduled but ultimately discarded before filming commenced. As a result, Johnston and the cast received daily script pages with no prior preparation, leaving them unaware of the overall narrative arc or character development.
This approach prevented the team from filming scenes in the same location consecutively, leading to increased costs as the crew shuttled between Hollywood soundstages and Hawaiian filming sites. Despite these challenges, Johnston poured his energy into the project, later admitting, “The final script wasn’t completed until after we finished shooting.”
5. Pirates of the Caribbean: At World’s End (2007)
It’s astonishing to think that the immensely successful Pirates of the Caribbean franchise originated from a theme park ride. Even more surprising is that the second and third films entered production without a clear storyline.
After the first Pirates film’s triumph, Disney set release dates and tasked director Gore Verbinski with creating two sequels. Consequently, he filmed Dead Man’s Chest and At World’s End back-to-back, sharing locations and sets. Initially, neither film had a script, and even as the second film’s script took shape, the third remained without one.
Relying solely on loose concepts from Dead Man’s Chest, Verbinski and his team crafted fragmented scenes for At World’s End during filming, ensuring they could reuse sets before dismantling them. This included shooting Captain Jack’s (Johnny Depp) climactic scene for the third movie just four days into filming the second, without knowing how it would fit into the overall story. Fortunately, the gamble paid off, as the two films collectively grossed approximately $2 billion.
4. Pretty Woman (1990)
The blockbuster romantic comedy Pretty Woman wasn’t initially conceived as a glamorous showcase for Richard Gere and Julia Roberts. Originally titled 3000, the script was far darker, portraying Roberts’ character, Vivian Ward, as a drug-addicted prostitute who ends up alone and penniless. However, the original production company collapsed, halting the project and leaving Roberts, who was already cast, in limbo.
Disney later acquired the project, providing funding and hiring Beaches director Garry Marshall. Despite this turnaround, Disney rejected the original script, leaving Marshall, the writers, and the cast to develop the story during filming.
When creativity stalled, Marshall would simply roll the camera, instructing his actors to “be funny” and allowing them to improvise. Marshall’s signature humor ultimately shaped the film into a defining romantic comedy of the late 20th century, securing its success.
3. Iron Man (2008)
As the foundation of the Marvel Cinematic Universe, Iron Man established the blueprint for the expansive superhero franchise, showcasing Robert Downey Jr.’s previously untapped charisma and star quality. Despite its pivotal role, the film’s production was far from the polished, well-oiled machine that later defined Marvel’s cinematic endeavors.
Before Iron Man, director Jon Favreau had only one major commercial success under his belt. Yet, producers Avi Arad and Kevin Feige saw potential in him, entrusting him with a $130 million budget. While Favreau excelled in casting—spotting Downey’s ideal fit for the complex billionaire Tony Stark and casting Jeff Bridges as the enigmatic mentor—the script remained a persistent challenge.
During pre-production, the script underwent numerous revisions, with contributions from various writers, including comic book authors. However, by the time filming began, the script lagged behind Favreau’s storyboards and planned sequences. This forced Downey, Bridges, Favreau, and the production team to improvise extensively, often crafting scenes and dialogue moments before shooting.
2. Casablanca (1942)
Few films boast the enduring legacy of Casablanca, a movie that has captivated audiences for over eight decades. Featuring Humphrey Bogart as Rick Blaine, a nightclub owner, the story unfolds a love triangle involving Rick, his former lover Ilsa Lund (Ingrid Bergman), and her current partner Victor Laszlo (Paul Henreid), all set against the dramatic backdrop of World War II.
While the film draws inspiration from Murray Burnett and Joan Alison’s unproduced play Everybody Comes to Rick’s, much of the screenplay was developed on the fly. Director Michael Curtiz pieced together scenes as production progressed, including the climactic finale. Bergman later revealed that the uncertainty of the ending left her unsure whether her character was meant to love Rick or Victor throughout the film.
This ambiguity brought out Bergman’s finest performance, but it had a different impact on Bogart. Frustrated by the lack of a finalized script, the iconic actor often appeared disgruntled on set and kept his distance from co-stars. Despite this, his undeniable charm shone through in every scene.
1. Edge of Tomorrow (2014)
The time-loop action film Edge of Tomorrow is celebrated as one of the standout original sci-fi movies of the 21st century. Starring Tom Cruise and Emily Blunt, the film’s success is no surprise. However, its path to the big screen was anything but smooth.
Despite starting with a fully written script by Dante Harper and a hefty $178 million budget, director Doug Liman discarded most of the original screenplay upon joining the project, retaining only the overarching themes and characters. This led to a revolving door of writers, including Jez and John-Henry Butterworth, Simon Kinberg, and Christopher McQuarrie, each submitting drafts in an attempt to meet Liman’s vision.
However, no version satisfied Liman, and production proceeded without a finalized script. Liman frequently adjusted plans on the fly, even insisting on reshooting the first day’s footage by the second day. Cruise and McQuarrie worked closely to refine the protagonist’s arc, and the third act was only developed as filming progressed. Despite these challenges, the team succeeded, paving the way for a planned sequel.
