Julia Roberts has revealed that Meryl Streep was 'cooler' then she ever imagined she would be.
Roberts teams up with fellow Oscar winner Streep, as the pair play mother and daughter in August: Osage County.
This is the first time that the pair have shared the screen together, and Roberts admits that she has thought about this moment for a long time.
Speaking to Marie Claire the actress said: "I had many imaginary conversations with Meryl about working together...
"When a person goes from being on a pedestal in your mind, to even cooler, better and more fabulous up close, you get to understand them a little more intimately."
August: Osage County is already being tipped as an Oscar contender and sees John Wells return to the director's chair.
Roberts and Streep are joined by an all star cast as Abigail Breslin, Benedict Cumberbatch, Ewan McGregor, Juliette Lewis and Chris Cooper are all set to star.
This will be the first big screen outing for Roberts since Mirror Mirror in 2012.
August: Osage County is released 17th January 2014.
