Sienna Miller Transforms into Carol Davis for NFL Biopic 'Madden'

Sienna Miller has transformed into Carol Davis, the former owner of the Las Vegas Raiders, for the upcoming biopic 'Madden.' First-look images show the 44-year-old actress sporting a blonde bouffant perm and channeling Davis's style in a teal jacket and matching necklace.

Miller stars opposite Christian Bale, 52, who plays NFL owner Al Davis. Carol Davis, who was part-owner of the Raiders with her husband and inherited his stake upon his death in 2011, passed away at age 93 in October of the previous year. She was often referred to as the First Lady of Raider Nation.

Christian Bale underwent a significant transformation for his role as Al Davis, shedding his usual appearance to become a dead ringer for the late owner. The film, directed by David O. Russell, focuses on the life of NFL coach John Madden, portrayed by Nicolas Cage, who is also nearly unrecognizable under prosthetics and a fat suit.

In a sneak peek, Bale as Al Davis is heard saying, "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." Cage, as Madden, is shown in character, frantically scribbling notes and expressing exasperation, "I have no idea where we are, who we are, where we're coming from or who we're throwing to."

The ensemble cast also includes Kathryn Hahn as John Madden's wife Virginia, Joel Murray as sportscaster Pat Summerall, and comedians Shane Gillis and John Mulaney, who plays business mogul Trip Hawkins.

This marks another collaboration between Russell and Bale, who previously worked together on 'The Fighter,' 'American Hustle,' and 'Amsterdam.' The film is scheduled for release on November 18 on Prime Video.
