Breakout: Funny how the smallest of roles often have the greatest impact.

Ms Kunis’ appearance in 2008’s Forgetting Sarah Marshall was notable as one of the best things about an otherwise middling comedy. Her easy charm and inherent likability meant that she instantly made fans of scriptwriter Jason Segel (“she made me look like a good writer”) and Darren Aronofsky (“she electrified me and made the screen sizzle”).

The latter is one of the reasons Kunis made this list. She’s currently shooting Aronofsky’s Black Swan alongside Natalie Portman. With whom she’s rumoured to share a smooch. “Nat is like every guy’s dream,” the actress shrugs. “She’s a nerd’s idea of heaven. The whole thing is silly, but I can see why people care.”

Also up in 2010, Kunis is starring in Tina Fey’s farcical Date Night, as well as the currently showing Book of Eli opposite Denzel Washington. And if her dulcet tones sound oddly familiar, it’s because she voices Meg in Family Guy.

Busy girl. And she’s only going to get busier.

Damaged Goods? Previous stabs at the film scene include the underwhelming likes of Max Payne and American Psycho II: All American Girl.
