Sienna Miller has revealed that she was intimidated by the guns on the set of her new blockbuster movie G.I Joe: The Rise of the Cobra.
The actress takes on the role of The Baroness in the live action adaptation of the G.I Joe: A Real American Hero toy franchise.
She told London Lite: "I can now do martial arts. I can fire weapons and I'm a good little scrapper. I had to get fit for the first time in my life.
"I did six weeks of fight training and initially firing guns was quite a big deal. I found it intimidating, not coming from a gun culture, and I couldn't do it without squinting."
Directed by Stephen Sommers, the man behind The Mummy and Van Helsing, G.I. Joe brings together an great cast of Dennis Quaid, Christopher Eccleston, Joseph Gordon-Levitt and new boy Channing Tatum.
The movie is also the first big blockbuster role for the British actress who is famed for her indie movies such as Factory Girl and The Edge of Love.
G.I Joe: The Rise of the Cobra is released 7th August.
