Dornan, 32, will play UN commander Pat Quinlan, caught in the Democratic Republic of Congo in the film, to be directed by debutante Richie Smyth, said The Hollywood Reporter.
"I can't wait to get stuck into Jadotville. It's an unbelievable story and Commandant Pat Quinlan is going to be a treat of a character to tackle.
"I'm a big fan of both Richie Smyth and (producer) Alan Moloney and I'm very much looking forward to working with them both," said Dornan in a statement.
"I'm really excited to be working with Jamie on The Siege of Jadotville," Smyth said.
"I thought his performance in 'The Fall' was sublime. He is perfectly cast in the lead role as Commandant Quinlan and has been instrumental in bringing this epic story to life," he added.
The film, which has been developed with the Irish Film Board and will be an official Ireland-South Africa co-production, is set to shoot in spring 2015 in Ireland and South Africa after Dornan finishes promoting 'Fifty Shades of Grey'.
