Michelle Williams provided a sneak preview of her transformation from girl-next-door to blonde bombshell Marilyn Monroe for new film My Week with Marilyn, with a photoshoot in Vogue.

Resembling the 1960’s sex symbol in photos snapped by celeb photographer Annie Liebovitz, Williams described in an interview with the fashion mag, the challenges of trying to gain weight to achieve Monroe’s hourglass figure.

"Ultimately, it went right to my face. So at some point it became a question of, Do I want my face to look like Marilyn Monroe's or my hips?"

Williams, 31, also spoke candidly about coming to terms with the death of her onetime partner Heath Ledger, with whom she had 5-year-old daughter Matilda.

"Three years ago, it felt like we didn't have anything, and now my life – our life – has kind of repaired itself," she says. "Look, it's not a perfectly operating system – there are holes and dips and electrical storms – but the basics are intact."

Williams also said Ledger’s death "changed how I see the world and how I interact on a daily basis. It's changed the parent I am. It's changed the friend I am. It's changed the kind of work that I really want to do. It's become the lens through which I see life – that it's all impermanent.”

The movie which dramatises Monroe's time filming 1957's The Prince and the Showgirl with Laurence Olivier is out on November 4.
