On Saturday, Sudanese Archbishop Daniel Deng will speak at a gathering of hundreds of activists opposite Number 10.
Mr Brown, who will meet the archbishop on Monday, said: "Sudan’s recent history has been one too often marked by violence, insecurity, and poverty for its people.
“Sudan’s leaders - with the support of the international community - must not allow this also to be the story of Sudan’s future.”
Violence flared again in 2009, with more than 2,000 people killed and 350,000 displaced in south Sudan.
A referendum is due to be held in January 2011 on independence for the south, but campaigners fear a return to conflict this year could put that vote at risk.
The Beat for Peace film, part of the broader Sudan365 campaign, features famous British drummers alongside musicians from Sudan and other countries, including Japan and Australia.
