Sandra Bullock's Greatest Fear

Don't be fooled by her sweet smile, silly sense of humor and customary cute comedies; Sandra Bullock is complicated, and she's all business. Indeed, Bullock is so ardent and animated as she pitches her way through an interview, one is moved to remark upon the sheer energy she bolts into a room, but one cannot get a word in edgewise.

She's a force to be reckoned with -- not only was she recently named the second most bankable female star (after Julia Roberts) by industry trade The Hollywood Reporter, but Bullock seems to work around the clock -- shouldering the marquee on several films a year as well as running her own successful production company, Fortis Films.

As a producer in her own right, Bullock's get-up-and-go rivals the frenetic pace of The City That Never Sleeps, where Fortis is based. "I love the business and the creative aspects of the business," she says, tipping her executive hat. "I don't know if I always want to be in front of the camera. But I love producing; I love the camaraderie, I love the adventures, I love the stress. It's sort of an investment with the next step of my career, where I want to go."
