Following the success of The Queen, Lady Margaret Thatcher is the next British female icon to be immortalised on the big screen.

The former prime minister will be the subject of a film set around the Falklands War. The as-yet untitled film, by Hollywood studio Pathe - who financed The Queen - and BBC Films will centre on the 17 days immediately prior to the war, portraying Lady Thatcher as an unpopular Prime Minister whose fortunes were transformed by her decision to reclaim the Falklands from Argentina in 1982.

According to trade newspaper Variety the film will show Maggie "wrestling with her own private fears, facing down the men who doubted her and forging her image as the Iron Lady".

The script is by Brian Fillis, who wrote Fanny Cradock biopic, Fear of Fanny, and produced by Damian Jones ( The History Boys and Kidulthood). No director is attached to the project yet.

But the golden question is who will play Lady Thatcher in the movie. Julia Davies, who starred in Fear of Fanny and TV comedy Nighty Night and even Hollywood star Sharon Stone's names have been thrown into the hat, but the chosen actress would need to master Lady Thatcher's distinctive voice.
