NEW YORK (November 12, 2012)--Anne Hathaway, 30, credits her new husband Adam Schulman for helping her get through the grueling filming of the screen adaptation of "Les Miserables."

In "Les Mis," Hathaway plays Fantine, a struggling, sickly mother forced into prostitution in 1800s Paris.

Hathaway lost 25 pounds and cut her hair for the role and told the December issue of Vogue, the part left her in a "state of deprivation, physical and emotional."

She said she felt easily overwhelmed and said Shulman was understanding and supportive.

The couple wed in September in Big Sur, Calif. 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.
