ACTOR turned documentary maker Ross Kemp said filming part of his new series 'Extreme World' in the North was "an eye opener".
He walked with marchers towards Ardoyne, the scene of sectarian clashes during the Troubles.
"You're not aware of a lot of what goes on there over in the UK, and a lot of young people have no idea about the Troubles and the issues that existed in Northern Ireland, so there is a generation of people across the UK that has no idea how dangerous a place it was," Kemp told the Irish Independent.
"For me it was very much about looking at where we are now, 15 years on from the Good Friday agreement, but there are still distant threats there.
"I hope that we allowed people with extreme views from both sides of the community have their say and we spoke to people who have genuine grievances, but I really wanted it to be non-judgmental, completely unbiased.
"There were people who actually thought I'd take sides, but that's not me and it's not what I'm interested in," he said.
Kemp has not ruled out returning to Ireland in the future to investigate gangland crime in Dublin and Limerick.
"We'll go anywhere - our team is always on the lookout for a subject.
"We want to inform an audience that is not interested in current affairs usually and to take an interest in what is happening across the world," he said.
"When I was younger we had hard-hitting current affairs coverage of the brutality that was happening. What's the point of having movies and PlayStation games showing violence when you can't show things going on in the real world? I'm fortunate that I can travel the world to do that." 'Extreme World' begins on Sky1 on January 21, 9pm.
