Sienna Miller is a British actress who also has American citizenship. She was born on 28 December 1981, moved to London as a toddler and went to school at Heathfield in Ascot. She began her career as a model, appearing in Italian Vogue and the 2003 Pirelli Calendar, and has also worked in fashion design.
Her screen debut came in South Kensington in 2001, followed by the television drama Keen Eddie in 2003. Her breakthrough came in 2004 with Layer Cake and Alfie, and she then played Edie Sedgwick in Factory Girl in 2006 and Caitlin Macnamara in The Edge of Love in 2008, the year she was nominated for the BAFTA Rising Star Award.
How Sienna Miller makes her money
Her income comes mainly from acting, and the modeling that started her career came first. After her breakthrough she was cast in commercial films such as Casanova in 2005 and G.I. Joe: The Rise of Cobra in 2009, where a lead in a studio release usually earns a larger fee than in independent work, and a film that finds a wide audience raises the offers that follow.
She returned to prominence with the television film The Girl in 2012, which earned her a BAFTA Television Award nomination and a Golden Globe nomination. Later work includes Foxcatcher and American Sniper in 2014, The Lost City of Z and Live by Night in 2016, and American Woman in 2018.
Television has been a growing part of that work, including the miniseries The Loudest Voice in 2019 and Anatomy of a Scandal in 2022. Her modeling background and her work as a fashion designer give her extra routes for brand and campaign income, although acting remains the largest source of earnings.
