Sienna Miller sported a blonde bouffant perm as she transformed into Las Vegas Raiders owner Carol Davis for her role in the movie Madden.
The actress, 44, is starring opposite Christian Bale, 52, who plays NFL owner Al Davis, in the upcoming picture.
Sienna is featuring in the role of Al Davis’ wife Carol, who part-owned the Raiders with her husband and inherited his stake when he died in 2011.
Carol, dubbed the First Lady of Raider Nation, passed away at the age of 93 in October last year.
Sienna channelled Carol with a teal jacket and matching necklace while smoking a cigarette in teaser shots ahead of the movie.
Madden is a biopic of NFL coach John Madden, played by Nicolas Cage, who himself was barely recognisable under his prosthetics, fat suit and wig.

Christian underwent the most startling transformation to play Al Davis, who was principal owner of the Oakland Raiders while Madden was head coach.
His matinee idol looks and English accent were nowhere to be detected as he disappeared under the makeup that morphed him into a dead ringer for Davis.
The glittering cast also includes Kathryn Hahn and comedians Shane Gillis and John Mulaney.
David O Russell, the filmmaker behind such movies as Flirting with Disaster, The Fighter, Silver Linings Playbook and American Hustle, is directing the movie.
In the sneak peek, Christian as Al Davis says: ‘There’s only one John Madden. They didn’t make another one. He is one of a kind. Football wouldn’t be football without him.’
Nicolas is also seen in character as Madden, acting out the chaotic thought process of the legendary football coach-turned-commentator.
While delivering commentary apparently to a TV camera, Madden is glimpsed frantically scribbling gibberish on a paper set up on an easel.
‘I have no idea where we are, who we are, where we’re coming from or who we’re throwing to,’ he says in a state of obvious exasperation.

Sportscaster Pat Summerall, played by Joel Murray, manages to retain his cool in reaction to Madden’s outburst, saying as calmly as possible: ‘Very interesting.’
Meanwhile Katheryn plays John Madden’s wife Virginia, amid a cast that includes Mulaney as business mogul Trip Hawkins.
Christian has had a longtime working relationship with Russell, going back to his starring role in the filmmaker’s 2010 drama The Fighter starring Mark Wahlberg.
The picture featured Christian in the role of real-life pro boxer Dicky Eklund, which he managed to acquire after both Brad Pitt and Matt Damon were cast in the part but withdrew from the project because of their schedules.
Russell and Christian reunited for 2013 crime comedy American Hustle, an all-star affair including Bradley Cooper, Amy Adams, Jeremy Renner and Jennifer Lawrence.
Most recently they worked together on the 2022 comedy mystery Amsterdam, which Christian not only acted in but also helped produce.
