You know that feeling when you're watching a movie and you have to pause it just to check Wikipedia because you’re convinced the main character was a real person? That’s the magic of Woody Allen’s 1999 mockumentary. It tells the story of Emmet Ray, a jazz guitarist who is arguably the second-best in the world—right behind Django Reinhardt. Except, Emmet Ray never existed. The sweet and lowdown cast did such a convincing job that even jazz aficionados sometimes catch themselves looking for his old 78s.
Sean Penn leads the pack here. It’s a weird role for him, honestly. At the time, Penn was known for being intense, brooding, and maybe a little bit terrifying in movies like Dead Man Walking. Then he shows up as this narcissistic, pimping, train-watching guitar virtuoso who cries when he hears beautiful music. It’s a performance that earned him an Oscar nomination, and it’s probably the most "human" Allen’s writing has felt in decades.
Sean Penn as the Man Who Wasn't There
Sean Penn plays Emmet Ray with this twitchy, arrogant energy that makes you want to punch him and hug him at the same time. He’s obsessed with his own greatness. But he’s also terrified. Specifically, he’s terrified of Django Reinhardt. There’s a scene where he faints just at the mention of the man’s name. Penn actually learned how to mimic the fingerings of a jazz guitarist for the film. While the actual music was recorded by the brilliant Howard Alden, Penn’s hands look right. That’s a detail most actors blow.
He carries this prop—a giant moon he sits on for his stage entrance—that symbolizes his ego and his fragility. It’s absurd. It’s funny. But Penn plays it straight.
The chemistry he has with the rest of the sweet and lowdown cast is what anchors the film’s mock-doc style. You have talking heads like Nat Hentoff and Douglas McGrath (the movie's co-writer) popping in to talk about Emmet as if they found his lost tapes in a dusty attic. It builds a world that feels lived-in.
Samantha Morton and the Power of Silence
If Penn is the heart of the movie’s comedy, Samantha Morton is its soul. She plays Hattie. Hattie is a mute laundress who falls for Emmet. Think about the challenge there. You’re acting opposite Sean Penn, who is chewing the scenery, and you can’t say a single word. Morton didn't just survive the role; she dominated it. She got an Oscar nomination too, which is incredibly rare for a silent performance in the modern era.
She uses her eyes. Sounds cliché, right? But it’s true.

Hattie is the "Sweet" to Emmet’s "Lowdown." She follows him to the tracks to watch trains—his weirdest hobby—and she eats huge plates of spaghetti while he rants about his genius. There is a specific kind of pathos Morton brings to the screen that keeps the movie from becoming a mean-spirited caricature of the 1930s jazz scene.
- She represents the audience.
- We see Emmet's flaws through her patience.
- Her eventual departure is the only time Emmet realizes he’s a disaster.
Uma Thurman and the Intellectual Foil
Then comes Blanche. Uma Thurman plays this socialite/slumming writer who wants to document Emmet’s life for a book. She’s the complete opposite of Hattie. Where Hattie is silent and pure, Blanche is talkative, manipulative, and deeply bored.
Thurman plays her with a sort of predatory grace. She doesn't love Emmet; she’s fascinated by him like a bug under a microscope. Her presence in the sweet and lowdown cast provides the necessary friction. She pushes Emmet to be even more of a jerk, which eventually leads to his undoing. It’s a great bit of casting because Thurman has that "high-society" look that contrasts perfectly with the smoky, grit-covered jazz clubs Penn frequents.
The Supporting Players You Might Have Missed
The depth of this cast goes way beyond the big three names. You’ve got Anthony LaPaglia playing Al Torrio, a gangster who manages Emmet. LaPaglia is one of those character actors who just disappears into the era. He feels like he walked off a 1930s movie set.
Then there’s Gretchen Mol. She has a smaller role as Ellie, but she adds to the tapestry of women who drift in and out of Emmet’s chaotic life.
And we have to talk about the music. Even though they aren't "actors" in the traditional sense, the musicians involved are part of the cast's DNA. Howard Alden didn't just play the guitar; he coached Penn. Dick Hyman arranged the music. Without their contribution, the illusion of Emmet Ray’s talent would have crumbled in the first five minutes. The jazz isn’t just background noise; it’s a character. It’s the only thing Emmet is actually good at.

Why the Casting Works Better Than Other Mockumentaries
Most mockumentaries, like Spinal Tap or Best in Show, go for the throat with comedy. They want you laughing at the absurdity. Sweet and Lowdown is different. It’s a drama that happens to be about a fake person. The sweet and lowdown cast treats the material with a reverence that makes the tragedy hit harder.
When Emmet is wandering the streets at the end, realizing he threw away the only woman who ever loved him for a career that’s stalling, it’s heartbreaking. You forget he’s a fictional creation of Woody Allen. You forget you're watching Sean Penn.
Real Context and Historical Roots
While Emmet Ray is fake, he’s a composite of real jazz legends. Woody Allen is a massive jazz fan—he plays the clarinet every Monday night in New York—so he pulled from real-life temperaments.
- Django Reinhardt: Obviously. The "Manouche" jazz legend who played with only two working fingers on his left hand.
- Joe Venuti: Known for his wild practical jokes and sometimes abrasive personality.
- Bix Beiderbecke: The quintessential "tragic jazz figure" who died young.
The cast had to study these archetypes. Penn, in particular, captures that specific brand of mid-century American masculinity—tough on the outside, but totally obsessed with the "purity" of art.
Actionable Takeaways for Film Lovers
If you're looking to revisit this film or watch it for the first time because of the cast, here is how to get the most out of the experience:
Watch the hands. Seriously. Look at Sean Penn's fingering during the solo on "I'll See You In My Dreams." It’s a masterclass in physical acting. He isn't just strumming; he’s mimicking the specific vibrato style of 1930s swing.

Contrast Hattie and Blanche. Notice how the lighting changes when Emmet is with Samantha Morton versus Uma Thurman. With Morton, it’s warm, golden, and soft. With Thurman, it becomes sharper and more "metropolitan." The cast's performance dictates the visual language of the film.
Listen to the "Experts." Pay attention to the interviews with people like Ben Duncan. They speak with such authority that it’s easy to forget they are describing scenes we just watched. It’s a brilliant narrative trick that only works because the actors in those scenes played them with such grounded reality.
Check out Howard Alden. If you like the music, don’t stop with the movie. Howard Alden is a living legend. Seeking out his actual discography gives you the real-world version of the Emmet Ray sound.
The sweet and lowdown cast remains one of the most underrated ensembles of the late 90s. It’s a movie about the gap between being a great artist and being a good human being. Usually, that gap is a canyon. Through Penn and Morton, we see exactly how lonely it is inside that space. Go back and watch the scene where Emmet watches the trains. It tells you more about his character than any page of dialogue ever could.
Next Steps for Enthusiasts:
To truly appreciate the performances, your next move should be listening to the original recordings of Django Reinhardt’s Minor Swing. Once you hear the "real" version of Emmet Ray’s idol, the nuances of Sean Penn’s performance—the fear, the imitation, and the desperate desire for approval—will become much clearer. You can also look up Samantha Morton’s interview regarding her "silent" preparation; she reportedly stayed in character on set to maintain the physical communication style she developed for Hattie.
