A decade of transformative work across drama, thriller, and comedy.
Cassie Howard
One of television's most emotionally complex and visually stunning dramas. Sydney's portrayal of Cassie Howard — a vulnerable yet volatile young woman navigating love, trauma, and identity — earned dual Emmy nominations.
Bea
Box office hit of 2024. A Shakespeare-inspired romantic comedy opposite Glen Powell that proved Sydney's star power at the cinema.
Reality Winner
A tightly wound real-time drama based entirely on the FBI's transcript of their interrogation of whistleblower Reality Winner. Solo masterclass in acting.
Producer & Lead Actress
Sydney's most personal producing project to date — a visceral, Italian-set horror film she developed, produced, and led from the front. Released 2024 to strong critical reception and passionate audience response.
Producer & Lead Actress
A gripping Apple TV+ thriller in which Sydney both produces and leads the cast — further cementing her reputation as one of Hollywood's most formidable actor-producers.
Founder & Producer
Founded in 2021, Fifty-Fifty Films is Sydney's independent production company — built on the principle of equal creative collaboration. The company actively develops original films and television projects.
