My Week With Marilyn

MICHELLE WILLIAMS

To get the blonde bombshell’s signature hip wiggle, the 41-year-old tied a belt around her knees on set of the 2011 flick that takes place during the shoot for 1957’s The Prince and the Showgirl. “There’s a tilt in her rump,” the actress, who earned an Oscar nod for the role, explained of the va-va-voom star. “She’s making an entrance and an exit.”

My Week With Marilyn depicts the frosty relationship between the actress and her costar Laurence Olivier (Kenneth Branagh).
