Journey, about civil war in the African country, will be Radcliffe's most serious role yet.
He will play Dan Eldon - one of four journalists killed in the attack in 1993.
Top Hollywood actors reportedly wanted the role but Eldon's family opted for Radcliffe.
His mother Kathy said: "We resisted a lot of older actors because Dan was a boy emerging into manhood."
