Dessie Curly himself, Colm Meaney, will play Martin McGuiness in The Journey, opposite an already cast Timothy Spall - portraying Sir Ian Paisley.
Nick Hamm is directing the film, which will examine, in a fictionalised account, the complicated and ultimately surprising relationship between the two men who started out as very much enemies, but became close, after being forced to take a short journey together.
Upon hearing of Paisley's death, a visibly emotional McGuiness declared "Once political opponents - I have lost a friend." So there is plenty here for both, extremely underrated actors, to get their teeth into.
Hamm last helmed Killing Bono, and has also directed Robert De Niro starrer Godsend and horror flick, The Hole.
