Sienna Miller and the long argument with the British press

The thing to understand about Sienna Miller is that the tabloids had her first. Before the films registered, before any award circuit knew the name, the British press had filed her as a category: It-Girl, fashion verb, the fiancée wronged by Jude Law, then the one photographed with Balthazar Getty. The performances ran underneath the noise — Tammy in Layer Cake, Nikki opposite Law in the Alfie remake, Edie Sedgwick in Factory Girl, Caitlin Macnamara opposite Keira Knightley in The Edge of Love. For roughly a decade what the public knew about her had almost nothing to do with what she was doing on set, and the gap between the two became its own subject. The quiet thing she has done since, role by role, is close that gap.

She was born in New York to an American banker and a South African-born model who had once worked as Bowie’s personal assistant, and the family moved to London before she could speak. Heathfield School, boarding in Berkshire. A short course at the Lee Strasberg Institute in New York when she was old enough to want acting more than she wanted Vogue covers, which she was also getting. The early CV is mixed on purpose: South Kensington opposite Rupert Everett, a TV role in Bedtime, a Fox pilot called Keen Eddie that died after one season. Layer Cake, Matthew Vaughn’s first feature with Daniel Craig as the unnamed dealer, gave her the moment everybody played back later — Tammy, the love interest who outranked the part — and Alfie put her in the same frame as her then-partner. By twenty-three she was a name on a magazine cover and a name in a court filing, and the second of those was the one that would not go away.

The mid-decade press cycle was its own genre. The News of the World hacked her voicemail and the Mirror Group did too; in 2011 News Corp settled with her for one hundred thousand pounds and she gave evidence at the Leveson Inquiry, where the cross-examination produced the single most quoted line about that whole period of British public life — the description of being chased down a dark street, at night, by ten grown men with cameras. The work she was doing while this was the news kept getting absorbed by the news. Factory Girl was reviewed as a tabloid event; Hippie Hippie Shake was shelved entirely; G.I. Joe: The Rise of Cobra collected her a Golden Raspberry, the only major prize the early career produced. She declared a break, moved sideways, and disappeared into theatre — Patrick Marber’s After Miss Julie on Broadway, then Flare Path at the Theatre Royal Haymarket opposite James Purefoy. The theatre years are where the rebuild happened. Nobody who walked into the Roundabout that season went looking for the famous girlfriend; what they saw was an actress carrying a Strindberg adaptation.

The screen reset came on television. The Girl, a co-production between HBO and the BBC, asked her to play Tippi Hedren under Hitchcock’s harassment — Toby Jones in the prosthetic — and she did it in a register the films had never let her into: still, mostly silent, all of the work in the eyes. The Golden Globe and the BAFTA nominations arrived. Two years later Bennett Miller cast her as Nancy Schultz, the wife of the wrestler John du Pont would shoot, in Foxcatcher. The same year Clint Eastwood cast her as Taya Kyle in American Sniper, the autobiography of the Navy SEAL Chris Kyle, which would become the highest-grossing war film ever made. Both roles were wives, both involved enormous men whose names were on the marquee, and both were structured around the moment her composure breaks. The pattern is what the next decade clarified. Live by Night and The Lost City of Z asked her to do the same job for Ben Affleck and James Gray. American Woman, Jake Scott’s working-class portrait of a Pennsylvania grandmother raising her grandson while waiting on a missing daughter, gave her a Gotham nomination and the British Independent Film Award nod that the early career had skipped past. Cabaret on Broadway gave her Sally Bowles; Cat on a Hot Tin Roof at the Apollo gave her Maggie.

The criticism worth making is that the parts kept being other people’s wives. Sophie Whitehouse in Anatomy of a Scandal — the Netflix miniseries adapted from Sarah Vaughan’s novel about a Conservative MP and a sexual assault trial — was the wife of a man whose entitlement she was supposed to be the audience surrogate to. Beth Ailes in The Loudest Voice was the wife and consigliere of Roger Ailes. Frances Kittredge in Kevin Costner’s Horizon, the western that opened theatrically in 2024 and lost its second instalment to studio mathematics, is a frontier widow. The line the camera keeps offering her is the woman who watches the man do the thing and then has to live with what he did. She has been refusing to play it as ennoblement and choosing the small dishonesties instead — Sophie’s slow recognition that her husband is who the prosecution says he is; Beth’s calculation that Fox will outlast Roger.

This spring she has been holding two of those marquees herself. Jack Ryan: Ghost War, the Amazon MGM feature spun off from the Krasinski series, premiered at Regal Times Square on the fifteenth of May, with Miller on the carpet a few days after the birth of her third child, her second with the actor Oli Green. Madden, David O. Russell’s biopic of the football coach with Nicolas Cage in the title role, drops on Prime Video at the end of November; she plays Carol Davis. Dominic West has signed on opposite her in War, the Sky and HBO legal thriller from the creator of Hijack and Lupin, ordered for two seasons. The actress the press wanted to put away with the 2000s is now in the part of a career where what the work is doing matters more than what the press is doing about it. The argument took twenty years; she has won the part she was arguing for.
