Hilary Swank's movie weight

Hilary Swank is set to gain 30lbs for her next movie role.

The actress - who lost a huge amount of weight to star in 2004 movie 'Million Dollar Baby', a role for which she won an Oscar - will pile on the pounds to appear in the movie adaptation of Mireille Guiliano's best-selling book 'French Women Don't Get Fat'.

A source close to the movie, which Hilary will also produce, told gossip website E! online: "She'll gain 20 to 30lbs. But it's no sweat. She has played a man before in 'Boys Don't Cry'. She can handle anything."

Hilary will play the manager of a champagne company in the film, who deals with skinny French women who eat calorific treats including bread, wine and cakes and never put on weight.

The actress is not the only star who has put on weight for a role.

Eva Longoria is currently putting on pounds to play Gabrielle Solis in hit US TV show 'Desperate Housewives', while Matt Damon gained weight to appear in upcoming movie 'The Informant'.

However, other actresses have taken the easy route by wearing a fat suit.
Meg Ryan 'gained' 140lbs for new movie 'My Mom's New Boyfriend' by wearing a padded outfit, while Gwyneth Paltrow did the same for 2001 movie 'Shallow Hal'.
