Over the last two decades, the film industry has seen its fair share of surprises, particularly unexpected box office hits. While big-budget blockbusters and franchise films usually dominate the charts, smaller or seemingly unremarkable movies become massive financial successes now and then. These unexpected hits often catch audiences and critics off guard, proving that marketing budgets and star-studded casts aren’t the only ingredients for box office gold.
The twentieth century had its fair share of such movies. From Steven Spielberg’s Jaws (1975), the 1977 Star Wars, Mad Max (1979), Ghost (1990), and Titanic (1997) to The Blair Witch Project (1999), these films defied expectations and shattered the Box Office. Although they had unconventional storylines at the time of their release, their triumph serves as reminders that anything is possible when a film connects with the audience. Here are movies of the 21st century whose Box Office earnings exceeded expectations.
My Big Fat Greek Wedding (2002)
Production Budget: $5 Million
Box Office Earnings: $368.7 Million
The Nia Vardalos-led cast of My Big Fat Greek Wedding is one of cinema’s biggest, most unexpected Box Office hits. The film had a modest $5 million budget with no big stars. The film is a romantic comedy about Toyota Portokalos, a Greek-American woman who falls in love with a non-Greek man, Ian Miller (John Corbett). It also follows the cultural chaos ensuing as she introduces him to her traditional and loud Greek family. My Big Fat Greek Wedding’s box-office success was surprising, particularly because of how it was produced.
Tom Hanks‘s wife, Rita Wilson (who’s of Greek descent), saw the 45-minute one-woman stage play and loved it. Nia Vardalos, who wrote and performed the play, had been looking to adapt it to screen. Having been turned down, Wilson convinced Hanks to see the play, approached Vardalos, and backed its production with his Playtone Production company. Unlike other movie executives, Hanks allowed Nia Vardalos to maintain the film’s story, authenticity, and vision. This encouraged Vardalos to play the lead and cast unknown Greek actors. So, $368.7 million in Box Office earnings, primarily from word-of-mouth publicity, was shocking and unexpected.
The Passion of the Christ (2004)
Production Budget: $30 Million
Box Office Earnings: $612.1 Million
The Mel Gibson-directed The Passion of the Christ isn’t the first movie centered around Jesus Christ. As such, its astronomical success came as a huge surprise. The Passion of the Christ focuses on the final 12 hours of Jesus Christ’s life, including his arrest, trial, crucifixion, and death. The film is known for its graphic and intense depiction of Jesus’ suffering, aiming to portray it with historical and emotional realism. The movie’s storyline is told mostly in Aramaic, Latin, and Hebrew (with subtitles). A major reason for its success was that it stuck closely to the Gospel narratives. Actor Jim Caviezel played Jesus in the film.
March of the Penguins (2005)
Production Budget: $8 Million
Box Office Earnings: $127.4 Million
While Hollywood is no stranger to award-winning documentaries, the success of the 2005 French feature-length nature documentary March of the Penguins was unexpected. Narrated by Morgan Freeman in the English version, it follows the incredible journey of emperor penguins in Antarctica. It showcases how the penguins endure brutal weather and immense physical challenges to mate, lay eggs, and raise their chicks. Besides its Box Office earnings, the movie won Best Documentary Feature at the 78th Academy Awards in 2006.
Borat (2006)
Production Budget: $18 Million
Box Office Earnings: $262.6 Million
Borat! Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan was not only surprising for its financial success but for how a bizarre, mockumentary-style comedy became a pop culture phenomenon. The satirical documentary follows Borat Sagdiyev (Sacha Baron Cohen), a fictional Kazakh journalist who travels across the United States to learn about American culture. Borat’s shock value and taboo-busting content created a ton of buzz and curiosity for audiences. Also, despite its crude humor, critics praised it for being clever, brave, and politically sharp.
Juno (2007)
Production Budget: $6.5–$7.5 Million
Box Office Earnings: $232.3 Million
Jason Reitman’s 2007 coming-of-age drama Juno felt real, flawed, and funny to audiences. This made it easy for viewers to connect emotionally with its story. Juno premiered at the Telluride Film Festival, got rave reviews, and quickly built momentum from word of mouth and a wider theatrical release. The film tells the story of Juno MacGuff (Elliot Page), a smart, quirky, and sarcastic 16-year-old who becomes unexpectedly pregnant and decides to give the baby up for adoption. Although it starred big names like Jennifer Garner, Jason Bateman, and a younger Michael Cera, the level of success it achieved was unimaginable. Unsurprisingly, of its four Oscar nominations, it won Best Original Screenplay.
Mamma Mia! (2008)
Production Budget: $52 Million
Box Office Earnings: $611.4 Million
While musicals have become mainstream in today’s Hollywood, back in 2008, musicals weren’t “hot.” Mamma Mia! had its theatrical release the same summer as The Dark Knight and Iron Man, so a campy ABBA musical seemed like a long shot. While its star-studded cast would naturally have drawn attention, the possibility of a musical grossing over half a billion at the Box Office was practically impossible. Mamma Mia! is another proof that, in the end, the film audience decides what will be a success.
Slumdog Millionaire (2008)
Production Budget: $15 Million
Box Office Earnings: $378.4 Million
The 2008 British drama Slumdog Millionaire was a major box office hit, shocking film enthusiasts worldwide. Its story follows Jamal Malik (Dev Patel), a poor teenager from the slums of Mumbai who becomes a contestant on the Indian version of Who Wants to Be a Millionaire? As he answers each question correctly, he’s accused of cheating.
During police interrogation, Jamal explains how each answer relates to a specific moment in his difficult life, including poverty, crime, and his enduring love for Latika (Freida Pinto). With a small budget, no big stars, and marketing muscle, it took the North American box Office by storm. While Western audiences didn’t typically flock to films set in India with a mix of English and Hindi, Slumdog Millionaire surprisingly resonated deeply with the American audience.
Parasite (2019)
Production Budget: About $11.4 Million
Box Office Earnings: $258.1 Million
Bong Joon Ho’s 2019 Parasite was another international film that did exceptionally well at the North American Box Office. The South Korean dark comedy thriller became a critical and commercial groundbreaking film. Historically, non-English films rarely break through in major global markets, but Parasite became the first South Korean film to gross $250 million worldwide.
Parasite follows the Kim family, who are poor and living in a semi-basement apartment in Seoul. They cunningly infiltrate the wealthy Park family’s household, each taking on roles without revealing they’re related. What starts as a clever con spirals into a tense and unpredictable story about class division, greed, and survival. With its Best Picture win at the 92nd Academy Awards, it became the first non-English-language to do so. It also won Best Director, Best Original Screenplay, and Best International Feature, becoming a major Oscar sweep in addition to its commercial success.
Barbie (2023)
Production Budget: $128–145 Million
Box Office Earnings: $1.446 Billion
While this might be a controversial addition to the list, considering the level of big-budget marketing involved, admittedly, Greta Gerwig’s Barbie made an unexpected, astronomical run at the Box Office. The movie was adapted from a fashion doll franchise. Although popular, it wasn’t something anyone would have expected to capture a large audience like it did.
To put things in a better perspective, Barbie went toe-to-toe with Christopher Nolan’s Oppenheimer (famously dubbed “Barbenheimer”) and won. Admittedly, Barbie had the backing of a major studio with a star-studded cast. However, its producers never dreamed it would gross a billion dollars at the Box Office. So, it makes the list, not because it wasn’t expected to be a success, but because it pulled in numbers that shocked industry watchers.
The Minecraft Movie (2025)
Production Budget: $150 Million
Box Office Earnings: $570.6 Million
Video game adaptations aren’t new to Hollywood. However, few could have predicted the scale of success The Minecraft Movie pulled off after its release. The film saw Jason Momoa perform another against-type role to perfection, starring alongside Jack Black, Danielle Brooks, Emma Myers, and Sebastian Hansen. A major part of the film’s success was its ability to tap into the nostalgia and creativity associated with the Minecraft video game franchise.
This resonated with fans of all ages, revitalizing interest in video game adaptations. With its big budget, the film was expected to make a profit. However, the speed with which it attained it makes it all unexpected. Besides becoming the second-highest-grossing film of 2025, as of April, it is currently the second-highest-grossing video game film of all time. This means it beat the Sonic the Hedgehog films, Pokémon Detective Pikachu, The Angry Birds Movie, and other famous video game-adapted films. The Minecraft Movie currently sits second to The Super Mario Bros. Movie.
