Emma Stone Perfects Her 'O' Face For 'The Ghosts Of Girlfriends Past'

And if those films don't break Emma out into a leading role, maybe it will be the romantic comedy she's been filming opposite the Next Big Thing of 1996.

"I am [one of] 'The Ghosts of Girlfriends Past," she laughed recently, describing her supernatural character in the film of the same name. "It's a take off on 'A Christmas Carol'. Matthew McConaughey plays Connor, this guy who's been sleeping around with a bunch of women, and has a heart of stone, and some ghosts come back to haunt him and bring him lessons about his past relationships and future relationships."

Overseen by "Mean Girls" director Mark Waters, the film also stars such notables as Jennifer Garner, Lacey Chabert, Michael Douglas and Robert Forster. "I think Matthew's in a different place now; obviously there's been a lot that's happened since 'How To Lose A Guy in 10 Days,' and all that," Stone said of what separates this film from McConaughey's romantic comedies of films past. "This is really a lesson in falling in love, and not taking the path of just sleeping around for his whole life; it's a very [meaty] lesson, especially to be haunted by people."

Although the film is contemporary, Stone will appear as a frozen-in-time former girlfriend of McConaughey's philanderer. "I'm his first girlfriend; I'm the girl he loses his virginity to," she laughed. "She's out of her mind."

And after building her improv skills opposite the likes of Jonah Hill, Michael Cera and Rainn Wilson, Stone said "Ghosts" gave her a new acting challenge that could serve her well if this spooky thing becomes a habit. "I've perfected my 'Oooooo!' totally," she bragged. "I like to throw a sheet over my head when I'm in my house now, and just pretend to be a ghost again."

Do you think Emma Stone has what it takes to be the Next Big Thing? Has Matthew McConaughey lived up to all the hype that surrounded his NBT emergence back in the mid-Nineties?
