Scarlett for me...she seems perfect...she even looks like Samus..

I just hope she'll kick ass instead of 'kiss' ass in such a movie >_>

Why is not my post here, well, I choosed Scarlet, but yeah Sharapova looks good too...

Adrienne Palicki of Friday Night Lights fame

Its these kind of questions that should be in the Poll of the Week on the front page.

My pick would be Tricia Helfer or Katie Sackhoff.

Scarlet looks very Samus-like. But would she have the attitude to be her? o_O

By the way, like the TC mentioned, Alba also did Dark Angel, which had a lot of stunts and action. So it wouldn't be completely based on her looks and fame if she got chosen to play Samus.

how bout supergirl in smallville , forgot her name though . my net is damn slow today to google as well

That's an easy choice:

They should use Roberta Murgo. She is a brazilian model. You probably have seen her face in certain fan made Samus Aran draw.

In my opinion, she is a lot more beautiful than any actress in your list.

Hum, a large choice of ladies, but none of them could be samus...
