The Hollywood Reporter said the 17-year-old actor, who has risen to fame playing the fictional Hogwarts student, will now take on the role of famed author Rudyard Kipling's son for the World War I drama.
Radcliffe will play 17-year-old Jack Kipling, who was able to join the military due to his famous father's efforts, but later went missing in action, never to be found again.
The film is based on a novel by David Haig, who will take on the role of the 'Jungle Book' author for the production, the Reporter said.
The actor said that the concept behind the film, which is scheduled to air next year on Britain's ITV, intrigued him and said that it is especially relevant given the current circumstances in the world.
'I've always been fascinated by the subject (of World War I) and I think it's as relevant today as it ever was, with young men still sacrificing their lives in the name of war,' Radcliffe told the newspaper.
