Violence ripped through the streets of capital Male over the summer (12) as activists demonstrated against new president Mohammed Waheed.
His appointment proved controversial in the Maldives as former leader Mohamed Nasheed claimed he was forced to resign at gunpoint earlier this year (12).
Bosses at Amnesty International have described the events as a "human rights crisis", and now stars from the stage and screen have called for political change.
Radiohead star Thom Yorke, acting couple Anna Friel and Rhys Ifans, and Edward Norton have also added their names to the open letter, which states, "A young and fragile democracy is under threat once more and we therefore call upon Mohammed Waheed to set a firm date for free and fair elections immediately, to end the culture of systematic police brutality and to release all political detainees including opposition leader Mohamed Nasheed.
"We also call upon the international community, including the British government and the rest of the Commonwealth, to condemn this latest campaign of harassment, to demand an end to all human rights abuses and to urge the current regime to hold democratic elections at the earliest opportunity."
