Portraying ex-Prime Minister Julia Gillard in the coming film adaptation of Kerry-Anne Walsh's The Stalking of Julia Gillard, Rachel Griffiths expressed how she personally views Ms Gillard.

"I don't think we've ever had a young ex-Prime Minister that has so much capacity," Ms Griffiths said in the Confidential on Nova radio show.

She recalled spending time with Ms Gillard.

"I've spent a little bit of time with her, enough to say it was very enjoyable and I look forward to doing more."

She noted that the film was made all the more interesting with the political trend involving politicians' wanting their story told through literature.

"Everybody is writing their books at the moment and that is kind of interesting. Everybody's point of view is coming out and we've needed that to happen so we've got the full picture too," she said.

The film adaptation, still in pre-production stage is for tentative release in 2015.

For Griffiths, the role was daunting.

"I am a bit daunted but it is not like I've signed on to play the young Marilyn Monroe where when every year passes I go, 'I've really got to get that under my belt' whereas with Julia I feel like I've got a few years."

On Nov 2013 interview with trade blog TV Tonight, Griffiths admitted that being chosen for the role was thrilling, particularly when she thinks about her being Australia's first prime minister.

"I believe that the creative and intellectual capacity of the team involved will produce a stunning drama that will reframe this historic period in our cultural and political life."

The adaptation is under the direction of Richard Keddie who had directed both Ms Gillard and Kevin Rudd for political advertisements for television.

During the same interview in 2013, Keddie said that the tale of Rudd vs Ms Gillard is "an incredible contemporary Australian story."

"When the truth is revealed I think Australians will be astounded. We're the right people to make this because we know the political scene really well. We know how to make these kind of stories. You have two incredible personalities in Rudd and Gillard."

The Stalking of Julia Gillard was awarded with the Prime Minister's Literary Award for general non-fiction given at the Australian Book Industry Awards dinner held Friday.
