EXCLUSIVE: Cameron Diaz Dances, Talks Singing Fears in ET's Behind the Scenes Look at 'Annie'


Cameron Diaz tells ET that singing is the most terrifying thing she's ever done for a movie, but in this exclusive behind-the-scenes footage from the set of Annie, it looks like she's got more fury than fear.

Fans will remember Cameron's less-than-stellar karaoke in My Best Friend's Wedding, but she made a 180-degree turnaround in the upcoming big-screen version of Annie, opening Dec. 19.

The new, contemporary take casts Quvenzhane Wallis in the title role: a young, happy foster kid who's also tough enough to make her way on the streets of New York.

Abandoned by her parents as a baby with the promise that they'd be back for her someday, it's been a hard knock life for Annie ever since thanks to her mean foster mom Miss Hannigan (played by Cameron).

But everything changes when the hard-nosed tycoon and New York mayoral candidate Will Stacks (Jamie Foxx) -- advised by his brilliant vp Grace (Rose Byrne) and his scheming campaign advisor, Guy (Bobby Cannavale) -- makes a thinly-veiled campaign move and takes her in. Stacks believes he's her guardian angel, but Annie's self-assured nature and sun-will-come-out-tomorrow outlook on life just might mean it's the other way around.

While singing may have been out of Cameron's comfort zone, dancing clearly was right up her alley, as evidenced in our footage. Check out the video to see Cameron bust out the robot with a dash of Madonna.
