VIDEO: Jennifer Aniston Talks Taking on Dramatic Role in Indie Film CAKE: 'I Really Was Ready'

In her upcoming independent film, CAKE, 'Friends' star Jennifer Aniston plays a woman suffering from chronic pain. She's out of friends, addicted to painkillers, and suicidal. On yesterday's CBS SUNDAY MORNING, the actress spoke about trying her hand at a more serious role. Watch the interview in full below!

"I really was ready to, you know, just disappear and really go into the depths of a character," Anniston says, explaining that she can relate to the role in many ways. I'm pretty on the edge. I mean, I can cry at a Pampers commercial!" she jokes. "You just act it, use your own emotions."

The part has already earned Aniston a Screen Actors Guild Award nomination and a Golden Globe nomination. There's already buzz her work in "Cake" could be worthy of an Academy Award nomination.

"We were a little teeny, weensy movie made for four dollars and we poured our hearts into it and everyone worked so hard, so that this is happening on top of that, it's just like a huge, giant, juicy cherry on top," Aniston says.

There's also a sense of accomplishment, too, that she could prove to others she was more than a rom-com or sitcom star.

"A little part of me saying, 'I told you so?'" she asks. "Maybe a teensy one."

Aniston also talks with Cowan about working as a waitress at a burger restaurant in New York City, about the impact of her parents' divorce on her childhood, how her father, actor John Aniston, didn't want her to go into acting, and about being engaged to actor Justin Theroux.

"The main thing is to try to just keep refocusing back on what you know is true and what makes you guys happy and, you know," Aniston says.
