Anne Hathaway credits her new husband Adam Shulman for helping her get through the grueling filming of the screen adaptation of Les Mis-erables.
In Les Mis, the 30-year-old actress plays Fantine, a struggling, sickly mother forced into prostitution in 1800s Paris.
Hathaway lost 25 pounds and cut her hair for the role.
She tells the December issue of Vogue, the part left her in a "state of deprivation - physical and emotional."
She felt easily overwhelmed and says Shulman was understanding and supportive.
The couple wed in September in Big Sur, California.
Hathaway wore a custom gown by Valentino, whom she collaborated with on the design. Working with the designer is a memory she says she will "treasure forever."
The December issue of Vogue hits stores Nov. 20.
