A new trailer for The Journey, which sees Colm Meaney star as Martin McGuinness and Timothy Spall play Ian Paisley, has been released.
The film will tell the story of Ian Paisley's unlikely friendship with McGuinness as the two men shared power in Stormont after decades of animosity. The pair eventually got the nickname "the chuckle brothers" on account of the clear bonhomie between the former foes.
The trailer centres on a short car journey taken by the two men during which they "take the biggest leap of faith and change the course of modern history."
Killing Bono's Nick Hamm has directed the project, with Co. Down-born novelist and screenwriter Colin Bateman having penned the script.
Shooting took place on location in Northern Ireland and Scotland.

Meaney recently praised the late Martin McGuinness before his death, saying he was an "extraordinary statesmen".
Speaking to the Press Association, Meaney said McGuinness had become "a real statesman", and that a united Ireland was "a laudable goal".
"I supported him in his candidacy for President of Ireland at the last election because I thought he was the most qualified person to do it.
"He's proved himself over the last 10 years to be a very astute politician and a remarkably competent statesman, which surprises a lot of people."
Ian Paisley's widow, Baroness Paisley, is reportedly boycotting The Journey, telling the Belfast News Letter: "I don't think it was written with great knowledge."
Hamm said his film is not a documentary but "a fictionalised, entertaining feel-good movie about peace".
"We were not looking for either side to feel comfortable with the film," he explained at the Toronto Film Festival. "Neither were we looking for either side to condemn the film. We were looking to present a balanced argument where both sides would be equally comfortable and equally uncomfortable."
