Peter Dinklage is to star in 'Three Billboards Out Of Ebbing, Missouri'.
The 'Game of Thrones' actor and Joh Hawkes have joined the cast of Martin McDonagh's revenge drama.
The pair join an already impressive call sheet which includes Woody Harrelson, Frances McDormand, Sam Rockwell, Caleb Landry Jones, Abbie Cornish and Lucas Hedges.
The plot of the movie centres around McDormand's character, a devastated mother trying to deal with the consequences of the rape and murder of her daughter.
After going to the police, the investigation stalls when the investigating officers seem more interested in being racist than finding those responsible.
So the anguished mother pays for a trio of giant adverts - the 'three billboards' in the title - to shame the sheriff and his deputy into action.
Harrelson will play the local sheriff with Cornish portraying his wife and Jones playing the billboard salesman.
Hawkes will be McDormand's ex-husband, with the 'Game of Thrones' star as a local man who has a crush on her, while Hedges is her son.
McDonagh has also written the screenplay for the film and it is expected to get a 2017 release.
