Once Upon a Time in Mumbai is one of the most popular Bollywood gangster films, loved for its dramatic storytelling, gripping characters, and intense portrayal of Mumbai’s underworld. But a common question among fans is: Is Once Upon a Time in Mumbai a real story? Is it based on actual events, or is it purely fictional?
This blog post explores the background of the film, the real-life inspirations behind it, and how much of the story reflects true crime history.
What Is Once Upon a Time in Mumbai?
Released in 2010 and directed by Milan Luthria, Once Upon a Time in Mumbai is a crime drama set in the 1970s and 1980s Mumbai. It tells the rise and fall of gangsters, focusing on the complex relationship between Sultan Mirza and Shoaib Khan. The film showcases power struggles, loyalty, love, and betrayal in the city’s criminal underworld.
The movie’s style, characters, and narrative captivated audiences, making it a cult classic.
Is Once Upon a Time in Mumbai Based on a True Story?

Yes and no. The film is loosely inspired by real-life Mumbai gangsters but is not a direct retelling of true events.
- Sultan Mirza’s character is based on the real gangster Haji Mastan, who was a prominent smuggler in Mumbai during the 1960s and 1970s.
- Shoaib Khan’s character is inspired by Dawood Ibrahim, one of India’s most notorious gangsters and a major figure in organized crime.
However, the film dramatizes many events and relationships for cinematic impact. It combines fact and fiction to tell a compelling story rather than presenting a documentary-style biography.
Real-Life Inspirations Behind the Film
Haji Mastan
Haji Mastan was a smuggler who rose to power in Mumbai during the 1960s. He was known for his influence, wealth, and connections in politics and Bollywood. Unlike violent gangsters, Mastan maintained a clean image and was respected in many circles.
Dawood Ibrahim
Dawood Ibrahim began his criminal career after Mastan’s era. He is infamous for smuggling, extortion, and involvement in organized crime. Dawood eventually fled India and became a global crime figure.
The film shows the transition from Mastan’s era to Dawood’s rise, representing the changing dynamics of Mumbai’s underworld.
How Much of the Movie Is True?

The filmmakers took creative liberties to add drama, romance, and action. Some facts are:
- The rivalry between Sultan and Shoaib is inspired by Mastan and Dawood’s relationship, but their actual interactions were less dramatic than shown.
- Personal relationships and love stories in the film are fictional.
- Many action sequences are exaggerated for entertainment.
The film aims to capture the mood of the times and the spirit of Mumbai’s gangster world rather than deliver a factual account.

- Using actual names and events as references
- Authentic set designs recreating 1970s Mumbai
