Who do you want as the next alien?

Seeing as how Species 5 will probably get made, I thought it would be interesting to know who you would pick for the role as lead actress/alien.

My picks would be as follows:
- Helena Mattsson - Has already said that she wanted to return (or so I've read somewhere) and I wouldn't mind seeing her again, though preferably in a prequel to the 4th movie or, less preferably, in a sequel where she survived the events in the 4th movie.
- Milla Jovovich - Doesn't mind nudity and would probably be up for it. Though she's probably too old and too action-oriented to do the job convincingly.
- Emily Browning - Has done some movies that had required her to be in the buff (Sleeping Beauty is one of them), so I guess she wouldn't mind doing the same stuff in Species 5. I don't know much else about her, other than the fact that she's 23 years old and has acted in Sucker Punch.
- Sunny Mabrey - Could return as Sara to pick up where the 3rd movie left off. I personally can't wait for her to return as she's my number 2 favorite alien (Miranda is #1). Though my guess would be that she probably doesn't want to do it anymore, since she's also absent from Species 4.

And those were my picks for potential actesses to take on the lead in a possible continuation of the Species-franchise. What would be your pick? Please share them here.
