5.) Olivia Thirlby: Yup, you've seen her in Juno, but she was in The Darkest Hour and in the Dredd remake. I clearly see her doing the indie thing but a path similar to Amanda Seyfried isn't out of the question.
4.) Jamie Chung: She did the horror thing with Sorority Row but hit the mainstream radar with Hangover 2 and Sucker Punch. She's going to go all dramatic in Eden but I can't wait to see her star with JGL in Premium Rush. Oh yeah she's in Shimizu's 7500. Her hotness is bound to turn heads but I see performance gold as well.
3.) Katrina Bowden: Sure she's been on 30 Rock, but it was her performance in Tucker and Dale vs Evil that made me notice Katrina Bowden. She's in American Reunion as well and we hit the jackpot because we all know she's in Piranha 3DD. That means there is 100% confirmation she will be in a bikini.
2.) Juno Temple: She's probably the most relative unknown of the 5, but she's been in a lot of shit according to her IMDB. Most notably she was in Year One and The Three Musketeers. But I noticed her in Gregg Araki's Kaboom where she goes all grunty and nakedy. But her upcoming slate is full of awesomeness. She's in The Dark Knight Rises (heard of it?), Killer Joe, Lovelace and a werewolf lesbian film called Jack and Diane with Jena Malone. God damn yay.
1.) Chloe Grace Moretz: Clearly not unknown to genre fans, Chloe Moretz was our dear Hit Girl in Kick Ass. Her filmography is extensive and she technically broke out as Abby in Let Me In. But at only 15, she's damn versatile as an actress taking roles in crime dramas like Texas Killing Fields. Obviously Hugo was fuckin huge as well but I'm curious as hell to see her in Dark Shadows.
Clearly she is our new Carrie and that will make her skyrocket into the filmdom stratosphere.
