This poll is so prone to populist people and brand identity.

With Avatar coming out later this year, she can proove she isn't just a one trick pony called Letty.

But they're dead.

Nikki Reed: She really hasn't been in that many movies but if she started acting more she could be some good competition.

Emma Watson: I know that people aren't gonna agree with me on this but I can see the potential in her. Let her get a few more movies other then HARRY POTTER under her belt and then she what happens.

Lindsey Lohan: Yea she might be in and out of rehab but I think that once she gets and finally STAYS cleaned up (if that will ever happen); She does have some talent, she's pretty, and she's still only like 25.

I'm sure theres more but that all I can think of right now.

anne hathaway i think will get better and better. i can not wait for her in alice in wonderland though the second princess diaries and bride wars was not her best.

racheal mcadams is great. i do wish she did more films. loved her in the notebook.

natalie portman, i loved her in garden state. i didn't even think Mr. Magorium's Wonder Emporium was that bad! (the commercial made me scared to watch it). i still need to watch the other bolyn girl though. i want to watch more from her.

emily blunt was great in devil wears prada! i want to watch her in her upcoming film young victoria which my friend wants to watch asap.

P.S. Michelle Trachtenburg was so cute with Panetierre and Meester, I hope she does more stuff!

Compared to Julia Roberts in her heyday the box-office numbers of Angelina Jolie and Anne Hathaway(the only actressess, Meryl Streep aside, considered 'reliable' box-office wise) don't compare. The fact that Roberts tried an Oscar-baity role (ERIN BROCKOVICH) and the film became her last huge success to date whilst Jolie and Hathaway's diversions into 'serious' acting have been ignored by the mass public speaks volumes.

Until we have a successful blockbuster which is targeted at EVERYONE (male and female) again which is headlined solely by a woman the question posed is a redundant one.

I vote for Saoirse Ronan. She was great in Atonement, and has some great roles coming up. The Lovely Bones with director Peter Jackson and she is filming The Way Back starring Colin Farell and Jim Sturguss, with director Peter Weir. Working on these movies, will surely get more people to recognize her. She is excellent with doing different accents also. Plus she is only 15.

Differences in acting ability aside there's nothing really distinctive about any of the young actressess listed whereas Roberts landed in a pool, and partially suceeded, where distinction among her peers was prized(aside from skin colour Whoopi Goldberg was as completely different a popular actress as Roberts was to a Susan Sarandon)

To use TWILIGHT as an example the focus has mostly been on Pattinson as opposed to Stewart, or indeed think back to TITANIC where Leo was given the credit (and top billing) over Kate Winslet, despite it being technically her film from the character standpoint. Despite the successes of Mamma Mia and Sex And the City the movie last summer the problem of finding actressess who can reliably draw audiences the way Will Smith or, to an extent, Johnny Depp can will continue.

Secondly, I don't see why more people aren't talking about Rachel McAdams. In '04 and '05 she WAS the it-girl. Mean Girls (I know that was a Lohan film, but I think McAdam's performance was the most enjoyable by far), The Notebook, Wedding Crashers. I even think that most people who saw Red Eye only went because she was in it (Cillian Murphy is barely a household name in the states). If she didn't take a break after that string of films, I believe she would already be Julia Roberts. She's very likeable, gorgeous, and quite talented.

I don't understand why so many people are rooting for for Page, Stewart, and Wood for the position. Though they are all very talented (particularly Wood), they will never be America's Sweethearts – as they've made it quite apparent that they don't want to be.

Lastly, there are two girls I'm quite surprised are not on the list – Kristen Bell and Mila Kunis. Kristen Bell is slowly becoming a household name and Mila is just great. Both are stunning and were fabulous in Forgetting Sarah Marshall. They might not be "there" yet, but they most certainly have a better chance than Hayden, Biel, Heigl, and Fox.

Side note – Why not Kate Hudson? I realize that she's probably blown her chances, but she's still under 30 and has a better chance than at least a quarter of the ladies on this list.
