Martin Scorsese’s 2013 film adapts Jordan Belfort’s 2007 memoir, but it is not a scene-by-scene retelling. The book is Belfort’s extended first-person account; the film selects and reshapes episodes into a feature-length rise-and-fall story, keeping his point of view while changing the scope, pace and presentation.
Is the movie based on Jordan Belfort’s memoir?
Yes. The source is Belfort’s autobiography, The Wolf of Wall Street, first published in 2007. The film, released in 2013, uses the memoir as its basis, but an adaptation is not a transcript: the screenwriter and director choose what to include and how to depict it. The American Film Institute’s catalog entry identifies the autobiography as the film’s source and describes its narration as Belfort’s subjective perspective.
Penguin Random House lists a 528-page Bantam paperback edition (ISBN 9780345549334), as well as ebook and audio editions. Its catalog gives September 25, 2007 as the ebook publication date and November 26, 2013 for the movie-tie-in paperback. Those are edition details, not a measure of how much material the film includes.
How do the book and movie handle point of view?
The memoir: Belfort narrates his own story
The memoir presents events in Belfort’s own words. That makes it a sustained self-narration, not an independent account or a neutral record. Claims about conduct in the book should be understood as Belfort’s perspective unless corroborated separately.

The film: subjective narration translated into cinema
The film preserves that perspective through Belfort’s voice-over and direct address to the audience. Screenwriter Terence Winter has explained that the memoir’s first-person voice and asides worked powerfully on the page but could not simply be transferred unchanged to the screen; voice-over and direct address offered cinematic equivalents. The AFI notes that the film also depicts aspects of Belfort’s imagination as events. So the movie’s images do not always function as a straightforward claim that something happened exactly as shown.
Why is the film shorter and more selective?
Winter described the adaptation as a problem of scale: “The book itself is massive, and if we had actually told the full story of Jordan it would be an 18-hour movie.” That was his estimate of the challenge, not the running time of an existing cut. To make a feature-length narrative, he said he selected moments that felt cinematic, combined characters and truncated timelines to avoid repetition while shaping a rise-and-fall arc.
Rank #2
As a result, the film foregrounds chosen episodes rather than attempting to include the whole memoir. This approach changes emphasis as well as length: a sequence selected for dramatic force can occupy more of the film’s attention than it does in a much longer written account. Winter described the aim as telling the story without repetition while honoring the book, not reproducing every passage in order.
The available adaptation accounts establish that characters and chronology were compressed, but they do not provide a verified chapter-by-chapter or scene-by-scene inventory of omissions and changes. It would therefore be misleading to claim that a particular passage was left out or a specific incident altered without checking both works directly.

- Used Book in Good Condition
Does the movie condemn or glamorize Belfort’s excess?
Its moral framing is disputed. In a 2014 interview reported by The Guardian, Belfort said, “For me, it’s important that the movie is viewed the right way, certainly as a cautionary tale.” The same newspaper documented criticism that the film’s depiction could glamorize financial excess. Those are competing interpretations, not a settled verdict shared by every viewer or critic.
The film’s subjective narration matters to that debate: audiences spend much of the story inside Belfort’s persuasive, self-interested point of view, while the movie’s selection and presentation shape how his rise and consequences register. The memoir likewise remains Belfort’s own telling. Neither should be treated by itself as an independent factual record of the events.
Quick Recap
Which version should you read or watch?
- Choose the memoir if you want Belfort’s more extended, first-person self-account and the space of a book-length narrative.
- Choose the film if you want Scorsese’s stylized, selective interpretation, shaped around cinematic episodes and a compressed feature arc.
- Use both for comparison if you want to see how a filmmaker turns a memoir’s voice and material into a different form. Read each as a distinct telling, not as a definitive factual record.
