Sienna Miller grew up in London. At the age of 18 she returned to her birth place, New York, to study acting at the Lee Strasberg Institute. After graduating, she acted in off-Broadway productions like Cigarettes and Chocolate. In 2001, she moved back to London and worked on TV shows including Bedtime and Keen Eddie. In 2003 she met Jude Law while filming Alfie. She has since starred in a range of movies from Factory Girl to G.I. Joe: The Rise Of The Cobra.
Sienna Miller was almost born in a theatre. Her mother reportedly went into labour when she was watching a performance of The Nutcracker Suite in New York.
In 2006 she launched a clothing line with her sister Savannah, called Twenty8Twelve. The company name is based on Sienna's birthday.
In 2005 she made her London stage debut in As You Like It. She took over the role of Rosalind after Helen McCrory became ill during a performance.
She was allegedly cast in the lead role in Factory Girl twice. She originally dropped out of the production because of scheduling conflicts.
In an interview with Parade, she revealed that her parents were pleased when she accepted her role in G.I.Joe: The Rise Of The Cobra. She said that "my parents were getting fed up of my intense dramas".
