Jennifer Aniston definitely put a lot of work into executing her starring role in the new drama film Cake.

During a recent interview, the former Friends star discussed the complex role she’s personally deemed as one of the most challenging in her career, thus far.

She revealed her character, Claire Simmons, is one of the most courageous she’s ever portrayed.

“Well my God, it’s just the farthest thing from anything I have ever done and when I read it, it was so exciting and I knew that this would be an extraordinary challenge,” she explained.

“I was so excited and so ready to just dive in and take it on and meeting Daniel [Barnz] and having this wonderful collaboration, it was everything that I hoped as an actor, and being given the opportunity, I was just so grateful.”

Now, it appears all of that hard work may be paying off! According to Press Association, the film is rumored to be an Oscar contender. Since its theatrical release on Sept. 8, the film has received laudable reviews and a number of accolades.

The film was also a big hit at the Toronto International Film Festival, which has raised speculation of a possible Oscar nomination for Aniston.

The We’re the Millers star’s work in the film has often been compared to Charlize Theron’s highly lauded Monster performance and Matthew McConaughey’s groundbreaking work in the biographical drama film Dallas Buyers Club.

Cake director Daniel Barnz recently weighed in with his sentiments of the film and its success thus far.

“When my life and producing partner Ben Barnz and I first read Cake just fourteen months ago, we knew we had to go to Jennifer Aniston. It was the most obvious un-obvious choice – she’s mega-talented, but we’ve never seen the whole range of her extraordinary comic and dramatic abilities showcased in one role.”
