Rosie was as surprised as anyone when she landed the film's lead role. "I went to the audition and really I knew nothing about the role," Huntington-Whiteley told MTV
. "I went in completely not knowing what I was doing. I left feeling not confident." She didn't have long to fret, though. A few days after the audition, director Michael Bay
called her up and gave her the news. "Yeah, you're the girl," she recalled him saying. "Transformers" wasn't the first time Huntington-Whiteley worked with Bay. They first met on the shoot for the 2009 Victoria's Secret Christmas commercial, where he reportedly dumped
her in the middle of the desert, wearing nothing but high heels, lingerie, and a cape, and had her walk, runway-style, a half-mile back to the set. A good introduction, no doubt, for working with the famously tough director.
