Portraying American author Taya Renae Kyle, the widow of US Navy SEAL Chris Kyle, she spent time with Chris Kyle’s widow to prepare for the role.

“I felt like I understood her,” Miller told People Magazine. “We Skyped and she told me stories about how they met and their marriage and the good and the bad. We would laugh and cry. When the time came to meet, I felt like we were really good friends already.”

She also read all the emails that the couple exchanged while Navy SEAL sniper Christopher Scott Kyle was in Iraq.

“I felt really wrong doing it. She gave us her blessing, so I knew it wasn’t morally wrong. They were so personal and sweet and never written with the intention of being read by anyone other than each other. I felt really uncomfortable, but I knew at the same time it was informative. Bradley and I had these points of reference and this shared experience to that personal world,” Miller told Variety in an interview.

The G.I. Joe: The Rise of Cobra actress accessorized with Harry Winston jewelry and completed the outfit with matching white Balenciaga ankle-strap sandals.

Do you find Sienna’s dress sexy or tacky? We like it, but Sienna should have opted for a different pair of shoes to go with this dress.
