But the Oscar-winning actress made sure that she does not fade into the distance at the festival opening tonight, when she dazzled in a daring backless blue dress, Daily Mail online reported.
The 40-year-old star flashed flesh in the strapless gown with a long train as she posed on the red carpet at the opening ceremony and premiere of Chinese film Tuan Yuan (Apart Together).
Despite the snowy weather, Zellweger managed to stay smiling as she posed for photographers.
Zellweger is one of a seven-member jury, headed by German director Werner Herzog, who will decide on the awards at the end of the 10 day festival on February 20.
Joining the Bridget Jones's Diary star on the panel is German actress Cornelia Froboess, Chinese actress Yu Nan, Spanish producer Jose Maria Morales, Somalian writer Nuruddin Farah and Italian director Francesca Comencini.
