"Friends" star Jennifer Aniston, known for featuring in romantic comedies like "Just Go With It" and "Marley & Me", is seen with greasy hair and no make-up in her new film "Cake". And the actress found it liberating to play the role.

In "Cake", the 45-year-old plays a woman suffering from addiction, rage issues and suicidal depression after a tragic accident leaves her scarred inside and out. She hasn't played a role like this in the past and liked going makeunder for the role.

"It's awesome and liberating to let that all go. And see yourself looking like that on a 50-foot screen," people.com quoted Aniston as saying.

Aniston also said she moved stiffly and with great discomfort, aided by a back brace, to play a woman suffering from chronic pain caused by a car accident.
