Keen Eddie (2003-2004)

Sienna Miller Plays Fiona Bickerton

Sienna Miller in Keen Eddie

Before Sienna Miller was starring alongside the likes of Kevin Costner in Horizon: An American Saga, she brought her unique charm to Keen Eddie, a short-lived but fan-loved action-comedy series on Fox. Created by J.H. Wyman, this 2003 show followed NYPD detective Eddie Arlette (played by Mark Valley) as he transferred to London to work with the British police. Sienna Miller plays Fiona Bickerton, Eddie’s mischievous and whip-smart roommate, who matches his energy beat for beat – and often steals the scene with her wit and style.

This was one of Sienna Miller’s earliest TV roles, but even then she was a commanding presence on screen. Fiona is cheeky, unpredictable, and very British, and Miller nailed every beat with sharp comedic timing and a flirtatious spark that made her character a fan favorite. Though Keen Eddie only lasted one season, it’s remembered for its high-energy tone, stylish visuals, and catchy soundtrack. The show gave Miller a chance to prove she could hold her own in a fast-paced series, and it remains a cult classic for fans who discovered it during its brief run. For those diving into the best Sienna Miller movies and TV shows, this quirky series is a hidden gem worth revisiting.

Apple TV+’s Extrapolations is an ambitious 2023 climate-change anthology series from creator Scott Z. Burns, known for writing 2011’s Contagion. Set across multiple decades, the show explores the human toll of environmental collapse. Sienna Miller appears in multiple episodes as Rebecca Shearer, a scientist and mother navigating a world altered by climate disaster. Her role isn’t just emotional – it’s urgent, raw, and deeply human.

Sienna Miller’s performance grounds the sci-fi premise of Extrapolation in real-world stakes. She brings depth to Rebecca, a woman torn between scientific truth and maternal instincts. What makes this one of the best Sienna Miller movies and TV shows is how she balances the personal with the global. Though Extrapolations is a sprawling ensemble series, Miller’s appearance left a lasting impression. The cast includes A-list names like Meryl Streep, Kit Harington, and Edward Norton, yet Miller’s quiet intensity stands out. She didn’t receive any major awards for the role, but critics praised her for anchoring the show’s message in emotion rather than spectacle.

The Mysteries Of Pittsburgh (2009)

Sienna Miller Plays Jane Bellwether

Sienna Miller in Mysteries of Pittsburgh

Based on the novel by Michael Chabon and directed by Rawson Marshall Thurber, 2009’s The Mysteries of Pittsburgh takes viewers on a coming-of-age ride through post-college uncertainty. Sienna Miller plays Jane Bellwether, a free-spirited, impulsive woman who draws the protagonist Art Bechstein (Jon Foster) into a web of romantic and personal exploration during one unforgettable summer. Jane is magnetic and a little dangerous, and Miller plays her with an alluring mix of chaos and charm.

While the movie itself received mixed reviews, critics largely agreed that Sienna Miller’s performance was one of The Mysteries of Pittsburgh’s biggest strengths. She captures the essence of a woman who tries to appear carefree to mask a deeper emotional complexity. The chemistry between Miller and Peter Sarsgaard’s character adds a dose of unpredictability, making their scenes electric. Though not a commercial hit, the film stands as a unique entry among the best Sienna Miller movies and TV shows, particularly for fans of literary adaptations and nuanced characters.

The Edge Of Love (2008)

Sienna Miller Plays Caitlin Thomas

Sienna Miller in The Edge Of Love

Set against the backdrop of World War II, The Edge of Love is a moody, intimate drama about friendship, passion, and poetry. Directed by John Maybury, the 2008 movie explores the tangled relationships surrounding the famous Welsh poet Dylan Thomas. Sienna Miller stars as Caitlin Thomas, Dylan’s wife, opposite Keira Knightley as Vera Phillips and Matthew Rhys as Dylan himself. It’s a gorgeously shot period piece that simmers with tension and longing.

As Caitlin, Sienna Miller taps into both fire and fragility. She’s a woman fiercely in love, often hurt, and determined to survive emotionally in a world falling apart. Her chemistry with Knightley is one of the film’s highlights – their friendship is complex, full of silent betrayals and mutual admiration. The role earned Miller a nomination for Best Supporting Actress at the British Independent Film Awards, and it’s easy to see why. Caitlin isn’t just a side character; she’s the storm at the center of the story. This role cemented Miller’s status as more than just a fashion icon – she could truly act, and powerfully so.

In Lasse Hallström’s 2005 period rom-com Casanova, Sienna Miller plays Francesca Bruni, a brilliant and headstrong woman who challenges none other than the legendary titular seducer himself, played by Heath Ledger. Set in 18th-century Venice, this romantic comedy is a playful romp filled with mistaken identities, feminist flair, and lavish costumes – and Miller absolutely dazzles as the woman who refuses to be wooed without a fight.

Francesca isn’t your typical period-piece heroine. She’s outspoken, witty, political, and fiercely independent. Sienna Miller gives the character a modern edge without losing the story’s whimsical tone. Her scenes with Ledger are full of chemistry, and together they elevate the film beyond just another historical rom-com. While Casanova isn’t the most serious movie Sienna Miller has starred in, it’s undeniably fun – and Miller’s performance is one of the reasons it works so well. It’s one of the best Sienna Miller movies and TV shows if you’re craving something stylish, sharp, and romantic.

Joe: The Rise of Cobra hit theaters in 2009, audiences were introduced to a wildly over-the-top action blockbuster packed with sci-fi tech, secret military units, and intense globe-trotting battles. Directed by Stephen Sommers, The Rise of Cobra was a live-action adaptation of the beloved cartoon and toy franchise – and Sienna Miller took a surprising turn as The Baroness, a villainess with killer style and even deadlier moves.

Sienna Miller embraced the campy comic book tone of G.I. Joe with full force, donning all-black leather, jet-black hair, and a textbook supervillainess smirk. As The Baroness, she delivered a performance that was both sensual and sinister, completely transforming herself into a ruthless operative of Cobra. It was a bold departure from her previous roles, and she clearly suited the role of antagonist in an action blockbuster well. She made The Baroness unforgettable, and her fight scenes alone are worth the watch. Among the best Sienna Miller movies and TV shows, G.I. Joe stands out for showing just how versatile – and villainous – she can be.

In Matthew Vaughn’s whimsical fantasy adventure Stardust, based on Neil Gaiman’s novel, Sienna Miller plays Victoria – an elegant yet hilariously self-absorbed village girl who sets the entire plot of the 2007 movie in motion. When young Tristan (Charlie Cox) vows to retrieve a fallen star to win her heart, Victoria becomes the symbol of superficial love, and Miller plays her with just the right amount of vanity and sly charm.

While her role is relatively small in screen time, Sienna Miller makes an impact. She leans into Victoria’s shallowness without making her cartoonish, making her both relatable and laugh-out-loud funny. It’s a great example of how Miller can elevate even supporting characters into something memorable. The cast includes the likes of Claire Danes, Michelle Pfeiffer, Robert De Niro, and Mark Strong, all of whom bring their A-game. Sienna Miller holds her own though, delivering a perfectly calibrated comedic performance. Stardust has since become a cult classic, beloved for its mix of fantasy, romance, and swashbuckling adventure.

Directed, co-written, and co-produced by Kevin Costner, Horizon: An American Saga – Chapter 1 is a sweeping Western epic that marks the beginning of a four-part cinematic journey through the American frontier. Sienna Miller stars as Frances Kittredge, a resilient settler caught in the crossfire of survival, legacy, and the brutal realities of expansion-era America. This is Sienna Miller in full command – tough, grounded, and emotionally raw.

In a genre that often sidelines women, Frances Kittredge is refreshingly layered, and Miller brings her to life with quiet intensity and fierce dignity.

Sienna Miller has impeccable chemistry with Costner, as well as the sprawling ensemble that also includes Sam Worthington, Jena Malone, and Jamie Campbell Bower. Under Costner’s direction, Miller is given space to breathe and fully inhabit a character shaped by hardship and hope. What’s more, as the Horizon saga continues, Frances’ story is expected to evolve even further. If you’re seeking the best Sienna Miller movies and TV shows from her more recent career, this modern Western epic is absolutely one to watch.

Factory Girl (2006)

Sienna Miller Plays Edie Sedgwick

Sienna Miller in Factory Girl

In 2006’s Factory Girl, Sienna Miller steps into the silver-haired shoes of Edie Sedgwick, the real-life 1960s socialite, fashion icon, and Andy Warhol’s most famous muse. Directed by George Hickenlooper, the biopic dives into Sedgwick’s meteoric rise in the New York art scene – and her tragic downfall. Factory Girl features Sienna Miller at her most transformative, disappearing into Edie’s world of glamour, heartbreak, and destructive excess. Miller delivers a haunting, career-defining performance that captures both Edie’s effervescent charm and her emotional fragility.

Sienna Miller earned critical acclaim for her work in Factory Girl, with many calling it the best portrayal of Sedgwick ever put to film. Factory Girl earns its place as one of the best Sienna Miller movies and TV shows is the sheer emotional depth she brings to Edie – there’s never a moment where she’s playing a caricature. From the iconic outfits to the devastating spiral, Miller’s Edie is magnetic, tragic, and impossible to forget. It’s a must-watch for fans of biopics and anyone curious about the darker side of fame.

Sienna Miller’s breakout performance came in 2004’s Layer Cake, and it’s not hard to see why. Directed by Matthew Vaughn in his debut and starring Daniel Craig just before his Bond days, this stylish British crime thriller marked a turning point in Miller’s career. She plays Tammy, the gorgeous girlfriend of a powerful drug dealer, who becomes an unexpected temptation for Craig’s unnamed protagonist – a man trying to leave the criminal world behind.

Miller doesn’t have a ton of screen time, but she makes every second count. Her introduction – set to Duran Duran’s “Ordinary World” – became iconic almost instantly. With her tousled blonde hair, smoky gaze, and magnetic presence, she was unforgettable. Miller brings an edge to Tammy perfectly suiting the British crime movie, hinting at the chaos and danger just beneath her surface. Her performance perfectly complements Vaughn’s sleek direction and the film’s pulsing energy. Layer Cake is sharp, thrilling, and endlessly rewatchable – and Miller’s star turn helped launch her into the mainstream. For many Sienna Miller fans, this movie is where their love of her acting began.
