Madonna identifies with Mrs Simpson
Madonna has said the success of the Oscar-winning The King's Speech gives audiences a point of reference for her new film, W.E.
The Like A Prayer singer's directorial effort tells the story of Wallis Simpson, the two-time American divorcee for whom King Edward VIII abdicated his throne in 1936.
The film - which stars Abbie Cornish and Andrea Riseborough - makes its world premiere out of competition this week at the Venice Film Festival.
Madonna said the two films examine the same historic period from distinct points of view.
She also told a news conference that she identifies with Mrs Simpson, because fame often reduces celebrities "to a soundbite".
Madonna said she received support for the project from both her two director ex-husbands, Sean Penn and Guy Ritchie.
