Next month, Academy Award winner Marion Cotillard hits the big screen in "Inception," a thriller about people who invade your dreams through the use of technology.

But the French-born beauty just might achieve a similar effect with her hauntingly beautiful photos in the July issue of Vogue.

Wearing a plum Dior silk-and-tulle bustier dress, Victoria's Secret lace bra, and just a hint of a smile, Cotillard -- who has appeared in a trio of Lady Dior short films -- is the picture of elegance on the magazine's cover.

Inside, Cotillard, who was photographed by Mario Testino, reclines seductively on a sofa in a Dolce & Gabbana long-sleeved lace dress and dusty-rose silk slip, and looks flirty in an Aquilano.Rimondi nude wool fitted dress, Cutler and Gross mustard sunglasses, and Christian Louboutin ruffled satin pumps.

Classic style is something in which Cotillard has become well versed, having played legendary French singer Edith Piaf in 2007's "La Vie en Rose" and a '60s Italian film star in the 2009 musical "Nine."

For the latter, she turned to Audrey Hepburn for inspiration and says that photos of the "Breakfast at Tiffany's" star gave her "the hairdo with the big personality, the thick bangs, and the ponytail. You paint your character with colors you have taken from everywhere."

Elsewhere in the magazine, Cotillard shows of her artistic side, playing photographer in a Louis Vuitton dress with a paint-print silk bustier and plaid cashmere-and-wool full skirt, Stella McCartney midnight-blue bra with dot trim, and Dior Timepieces watch, as well as a Nina Ricci fuchsia silk-and-slate flannel ruched dress and rosette-bouquet silk-chiffon cummerbund topped off with Vera Wang sunglasses.

Testino's photos reflect Cotillard's bohemian spirit, as does the actress's personal passion: playing in the Expressionist-Surrealist band Yodelice. "I play the bass guitar, keyboard, and tambourine," says Cotillard, who dresses as a man and goes by the name "Simone" when she performs with the band.

Says Cotillard, "It's pretty refreshing to be in a situation where the spotlight is on someone else."
