Forest Whitaker is in talks to play Martin Luther King Jr in film Memphis.
The film is being made by writer and director Paul Greengrass who will shoot it in a similar docu-style manner to United 93, says The Wrap.
It will follow Martin Luther King's final days trying to balance his personal and professional life while he organises the protest march in Memphis where he was assassinated.
The action also follows the FBI who had been wire tapping King, and launched a manhunt for his killer, James Earl Ray.
The King family are developing their own project at DreamWorks and are said to have objected to the warts-and-all portrayal in Memphis.
It will include King's worries about the state of his marriage and of America, and his fears of being overtaken by younger black leaders.
Forest, who won an Oscar for The Last King of Scotland, can be seen later this year in The Butler with John Cusack, Out of the Furnace with Christian Bale and Black Nativity with Jennifer Hudson.
