Anna-Maria Sieklucka is a Polish actress, singer, and dancer born on May 31, 1992, in Lublin, eastern Poland. She rose to global stardom with her lead role as Laura Biel in the Netflix erotic drama 365 Days (2020) and its two sequels.
With a background rooted in theatre and a command of four languages.
Sieklucka has been steadily expanding her career beyond the franchise that made her famous. Most recently starring in the 2025 thriller Compulsion alongside Charlotte Kirk.
Early Life and Education
Anna-Maria Sieklucka was born and raised in Lublin, Poland, growing up in a family headed by her father Jerzy Antoni Sieklucki, a well-known local lawyer.
From a young age, she was drawn to performing arts, dance, and storytelling.
After completing her secondary education at II Liceum Ogólnokształcące im. Hetmana Jana Zamoyskiego in Lublin, she pursued acting at the AST National Academy of Theatre Arts in Wrocław.
She graduated in 2018 from the Faculty of Puppetry — a rigorous program that shaped her stage presence and technical skills.
One of her most remarkable assets is her multilingual ability: Sieklucka speaks fluent Polish, English, French, and German, giving her a distinct edge in international productions.
Theatre Career and Early Roles
Long before Netflix came calling, Sieklucka built her craft on the stage.
She performed in notable theatrical productions, including Ivan Vyrypaev’s Valentine’s Day, and toured internationally with Marta Gornicka’s Chorus of Women Magnificat performing in Salzburg at the Sommerszene Festival and in Madrid at the Teatros Canal.
Her television debut came in October 2019, when she appeared in an episode of the popular Polish medical drama Na dobre i na złe, playing the character Aniela Grabek. It was a small but meaningful step toward the screen.
Even after achieving film fame, Sieklucka never abandoned the theatre. She took on the role of ‘Death’ in Margules. Ausencia, a biographical stage play about Polish-born Mexican director Ludwik Margules, directed by her partner Łukasz Witt-Michałowski.
Breakthrough: 365 Days (2020)
In 2020, Sieklucka landed the lead role of Laura Biel in 365 Days — a multilingual Netflix erotic drama based on Blanka Lipińska’s bestselling novel trilogy. The film follows a spirited young woman kidnapped by a Sicilian mobster who gives her 365 days to fall in love with him, opposite Italian actor Michele Morrone.
Sieklucka has admitted she was initially hesitant to accept the role after reading the script, but ultimately overcame her reservations. The film was panned by critics and earned a 0% rating on Rotten Tomatoes, yet it became a viral sensation and was reportedly the most-watched Netflix movie globally in 2020.
The role earned Sieklucka a Razzie nomination for Worst Actress — but it also launched her into international stardom, amassing millions of followers on Instagram virtually overnight.
The 365 Days Sequels
Netflix greenlit two sequels simultaneously in May 2021, and Sieklucka reprised her role as Laura — now Laura Torricelli — in both 365 Days: This Day and The Next 365 Days, both released in 2022. The films introduced new cast member Simone Sussina as a rival love interest, raising the dramatic stakes.
Both sequels were met with even sharper critical backlash than the original, picking up additional Razzie nominations. Despite the reviews, the franchise retained a fierce global fanbase and cemented Sieklucka’s status as one of the most recognizable Polish actresses in the world.
Sieklucka has been open about her desire to step beyond the franchise and take on more diverse and challenging roles in different genres.
Compulsion (2025) and New Directions
In a bold career pivot, Sieklucka starred as Evie in Compulsion (2025), a dark erotic thriller directed by Neil Marshall (The Descent) and distributed by Saban Films.
The film centers on two women entangled in a series of horrifying murders on the island of Malta, with Sieklucka opposite Charlotte Kirk and Zach McGowan.
The film had its world premiere at the Mediterrane Film Festival in Malta on June 28, 2025, before its US theatrical release in September 2025.
It was rated R for strong violence, sexual content, and nudity — signaling Sieklucka’s willingness to tackle complex, genre-driven roles outside her 365 Days comfort zone.
Critics described Compulsion as an uneven but stylish homage to 1980s and ’90s erotic thrillers like Fatal Attraction and Basic Instinct, with Sieklucka’s performance drawing mixed but notable attention.
Fashion, Lifestyle, and Public Persona
Away from film sets, Sieklucka has become a recognizable face on the European fashion circuit. She has been a recurring guest at Marc Cain’s Berlin Fashion Week shows, attending editions in 2024, January 2025 (Fall/Winter), July 2025 (Spring/Summer 2026), and most recently the “Echo of Now” Fall/Winter 2026 show at Funkhaus Berlin in January 2026.
Her Instagram account (@anna_maria.sieklucka) boasts over 4 million followers, where she shares fashion looks, travel, and glimpses of her artistic life. She is known among fans as ‘AMA’ and describes herself as a wanderer and soul-searcher.
Off-screen, Sieklucka is known to be private and grounded. She enjoys traveling, cooking, visiting art galleries, and exploring new spices — a far cry from the glamorous intensity of her on-screen roles.
Personal Life and Relationship
Sieklucka is in a long-term relationship with Łukasz Witt-Michałowski, a respected Polish theatre director and actor from Lublin who is 18 years her senior.
The two met during her time at the AST National Academy of Theatre Arts in Wrocław, where he was involved in productions.
Witt-Michałowski is known in Polish theatre circles for directing works such as Pogrom Next Tuesday and Hunger by Knut Hamsun, and he was awarded the Nagroda Prezydenta Miasta Lublin for Promoting Culture in 2010.
Their relationship has been a strong creative bond as much as a personal one.
Sieklucka keeps her private life largely out of the spotlight, rarely commenting on her relationship publicly a deliberate choice that reflects her shy and introspective personality away from the camera.
Net Worth and Legacy
Anna-Maria Sieklucka’s estimated net worth ranges between $2 million and $4 million as of 2026, drawn from acting fees, brand endorsements, modeling contracts, and social media sponsorships.
Her income has grown significantly since the global success of the 365 Days franchise.
Despite the controversy surrounding her breakout films, Sieklucka has proven herself a versatile performer willing to take risks from international film thrillers to avant-garde theatre.
She is passionate about growing as an actress and taking on emotionally demanding, genre-diverse roles.
At just 33, she is one of the most internationally recognized Polish actresses of her generation a distinction built not just on a viral Netflix hit, but on years of dedicated stage work and a fearless approach to her craft.
