Not only is Nicole Kidman our March cover girl, but she also stars as the beautiful and iconic princess and actress Grace Kelly in Grace of Monaco. The first trailer for the film is now here, giving us an enticing glimpse of the 46-year-old Kidman in her new role. Set in 1962, six years after Kelly's "Wedding of the Century," the film portrays a year in the life of the princess as she attempts to reconcile her acting career with her roles as a mother, monarch of a European principality, and wife to Prince Ranier III. While playing Kelly is a daunting task, Kidman has proven that she can shine when faced with a difficult role. "I always try to push through fear," Kidman says in the March InStyle. "People always say, ‘Oh, you take such risks,’ or ‘You’re brave.’ And I’m like, ‘Well, if you only knew—inside I’m really frightened!'"

Also starring Tim Roth, Frank Langella, Parker Posey, Milo Ventimiglia, Derek Jacobi, and Paz Vega, the much buzzed about Grace of Monaco is set to open the Cannes Film Festival in May. Check out the trailer above—and get ready to watch Kidman take on the elegant and beautiful Kelly in what may be her most compelling role yet.
