Long before he became the unforgettable patriarch John Dutton in Yellowstone, Kevin Costner was one of Hollywood’s most bankable movie stars. Throughout the late 1980s and 1990s, he delivered a string of iconic performances in films such as Field of Dreams, The Untouchables, Dances with Wolves, and The Bodyguard, establishing himself as one of the industry’s biggest leading men.

But even at the height of his fame, not every role was embraced by critics or audiences.

Among the most debated performances of Costner’s career remains his portrayal of the legendary outlaw in 1991’s Robin Hood: Prince of Thieves—a film that became a massive box-office success while simultaneously earning criticism for one aspect that fans continue to discuss more than three decades later.

Ironically, many viewers believe that the movie’s biggest weakness wasn’t its script, action sequences, or production values—it was Kevin Costner himself.

Directed by Kevin Reynolds, Robin Hood: Prince of Thieves was one of the biggest films of 1991. It finished as the second-highest-grossing domestic release of the year, trailing only Terminator 2: Judgment Day. Featuring large-scale action, lavish production, and Bryan Adams’ chart-topping ballad “(Everything I Do) I Do It for You,” the film became a worldwide phenomenon.

Despite its commercial triumph, critics were far less enthusiastic about Costner’s performance.

One of the most common complaints centered on his inability—or refusal—to convincingly adopt an English accent while portraying one of Britain’s most famous folk heroes.

Reviewers argued that the decision made it difficult for audiences to fully believe Costner as Robin Hood. The Los Angeles Times described his portrayal as one of the least convincing versions of the legendary hero ever brought to the screen, while Variety criticized the performance as stiff and lacking authenticity.

Over the years, that criticism has only grown louder.

Even today, discussions about Robin Hood: Prince of Thieves frequently return to the same topic. On Reddit and other fan forums, many viewers argue that replacing Costner with an actor capable of delivering a convincing English accent could have transformed the film.

One fan summarized the popular opinion by writing that Costner’s overall acting “wasn’t terrible,” but that the accent became such a distraction that audiences began noticing flaws they might otherwise have overlooked.

According to many fans, the performance itself wasn’t necessarily disastrous—it was simply impossible to separate Robin Hood from Costner’s unmistakably American voice.

Yet the film succeeded anyway.

Much of that success, many believe, came from another unforgettable performance: Alan Rickman as the Sheriff of Nottingham.

Rickman delivered what many critics now consider one of the greatest movie villains of the 1990s. His sarcastic wit, theatrical delivery, and delightfully over-the-top menace stole nearly every scene in which he appeared.

Whether threatening to cancel Christmas or delivering razor-sharp one-liners, Rickman’s Sheriff became the character audiences remembered long after leaving the theater.

In fact, his performance became so popular during test screenings that it reportedly created an unexpected problem for the filmmakers.

According to later reports, preview audiences responded so enthusiastically to Rickman’s villain that producers worried he was overshadowing Costner’s hero. Several of the Sheriff’s scenes were reportedly trimmed before the film’s theatrical release in an effort to keep the focus on Robin Hood.

Director Kevin Reynolds was said to be unhappy with some of those editing decisions, and reports have long suggested that creative disagreements contributed to tension behind the scenes before the film reached theaters.

Even with those changes, Rickman’s performance continued to dominate conversations about the movie.

Over time, Robin Hood: Prince of Thieves has developed an unusual legacy.

It remains one of Kevin Costner’s most commercially successful films, yet it is also frequently cited as one of his most criticized performances. At the same time, Alan Rickman’s unforgettable portrayal of the Sheriff of Nottingham has become widely regarded as one of cinema’s greatest villains—often remembered even more vividly than the film’s hero.

Today, many fans view the movie as an entertaining adventure elevated by its supporting cast rather than its leading man.

Still, the film’s enduring popularity demonstrates that even a performance dividing critics and audiences cannot always prevent a movie from becoming a blockbuster.

More than 30 years after its release, Robin Hood: Prince of Thieves continues to spark debate. Some viewers see it as a nostalgic action classic filled with memorable performances and iconic music. Others remain convinced that Kevin Costner’s portrayal prevented it from becoming a truly great adaptation of the legendary outlaw.

Either way, one thing is undeniable: few Hollywood blockbusters have inspired such a lasting contradiction—where a film became one of the biggest hits of its era while its leading performance remained one of the most hotly debated aspects of its legacy.
