Kemp's documentaries have previously looked at some of the world's most volatile situations and have seen him investigate issues like child soldiers in the Congo and deadly drug cartels in Mexico.
Now, the former EastEnders actor is looking at sectarian tensions surrounding the annual Twelfth of July celebrations in Belfast.
As well as police, Kemp has also spoken to both bandsmen and protestors and has been filming at an Eleventh Night bonfire off the Shankill Road and along a parade route in the Ardoyne area in the north of the city.
Serious violence has flared there in past years, with officers coming under attack as they try to bring order to riot situations involving petrol bombs, other missiles, and even shots being fired.
Efforts have been made to reach agreements between loyalist marchers and nationalist residents.
On Friday, Kemp walked with the feeder parade past the Ardoyne shopfronts before joining the main parade to Barnett's Demesne - passing another flashpoint at the Catholic St Patrick's Church on Donegall Street.
The new series of Extreme World is due to be aired on Sky 1 later this year.
