[NEWS] Jennifer Takes the 'Cake' in Her Latest Film Role

Jennifer Aniston as Claire Simmons in 'Cake'

It's always inspiring to witness a rare act of transformation, especially when it involves someone we've come to know and admire, in this case Jennifer Aniston. When she first appears onscrean in Daniel Barnz's new film, 'Cake', we are instantly aware that her character will be nothing like the irresistibly fetching Rachel Green she embodied for a decade on NBC's sitcom 'Friends'. Although the actress has taken on many winning movie roles since 'Friends' left the airwaves, stepping into the skin of her character Claire Simmons - a cynical, complicated forty-something woman who is addicted to prescription painkillers as a result of an auto accident that has left her emotionally and physically scarred - was no small feat for Miss Aniston. "To inhabit the role, I gained weight, quit exercising, wore no make-up and hid my famously luxuriant head of hair under a less than flattering short cut," said Jennifer of her role. The physical self-makeover alone is stunning, but even more impressive than her performance is the courage it took her to step up to such a challenging assignment - the leap earned her critical acclaim - a Golden Globe, Critic's Choice, and Screen Actors Guild award nominations for 'Best Lead Actress of the Year' - and a whole new fan base. Of course, Jennifer isn't the first actor to make such a dramatic leap away from the type cast role, but each time it happens it's exciting to see.

Getting swung around by a giant monkey in (1976) 'King Kong' wasn't exactly the most auspicious film debut for actress Jessica Lange, but five years later, two back-to-back roles would give her the opportunity to show her powerful movie mettle: as they adulterous hash-slinger Cora (1981) 'The Postman Always Rings Twice' opposite actor Jack Nicholson, and as the blacklisted - and ultimately institutionalized - actress Frances Farmer in (1982) 'Frances'.
