The former EastEnders actor turned investigative journalist is currently in Northern Ireland filming for the new series of his Sky1 show Extreme World.
And he received first-hand insight into parading tensions when joined bands as they paraded through north Belfast.
He walked with marchers towards Ardoyne, the scene of fierce sectarian clashes in recent years.
This year’s parade will be unprecedented following the ruling by the Parades Commission that Orangemen cannot walk along the stretch of road adjacent to the Ardoyne shops, where most of the trouble in the past has erupted.
An Orange Order source said no official approach had been made to the Order by the film makers, but they were aware of their intentions and happy to facilitate the documentary makers.
Earlier this year Kemp spent time in Londonderry, also for the forthcoming series of his show.
Kemp was at PSNI headquarters on Tuesday where he watched on as Chief Constable Matt Baggott gave a press conference ahead of the Twelfth.
And on Wednesday evening he talked to protesters in Ardoyne.
Previous programmes in the series have seen him infiltrate Venezuela's lawless prisons to lift the lid on Chavez's controversial regime, and in the Congo Kemp exposed the militias responsible for an epidemic of sexual violence against women.
He said: “I'm incredibly proud of the films we make for Sky 1.
“We remain dedicated to giving a voice to those caught up in some of the most extreme situations throughout the world.”
The third series of Extreme World will be screened in November.
