A documentary maker who was filmed naked, screaming and pounding the pavement has appeared on Oprah's Next Chapter to explain what led to his very public meltdown.

Kony 2012 film maker Jason Russell, who is also co-founder of the charity Invisible Children, was taken into psychiatric care after the incident in March.

Close-up footage of the evangelical Christian ranting about the devil was posted exclusively by TMZ, showing the nude father-of-two thumping the ground in San Diego, gesticulating and clapping.

Witnesses to the incident also claimed he vandalised cars and masturbated in public.

Now the 30-year-old, who is the mastermind responsible for the 30-minute documentary which details the ongoing conflict in Uganda and the plight of child soldiers, has recorded an interview with chat show host Oprah explaining the incident.

In a preview ahead of the October 7 show obtained by TMZ, he told Oprah he remembered tipping over cars, running around a lemon tree and lying in the road.

When Oprah asked him how he came to be naked, he replied: "It's really hard to explain to people who have never had an out-of-body experience, but it really wasn't me.

"That wasn't me, that person on the street corner ranting and raving and naked is not me, that's not who I am."

He added: "I remember walking around snapping my fingers up and down ... slapping my hands on the ground as hard as I can. Just slapping them on the ground.

"Talking to myself. Ranting. Raving. Talking about good versus evil, God and the devil. I mean it was just very out of control."

Shortly after the incident occurred, Russell's wife Danica released a statement claiming her husband had dedicated his adult life to Invisible Children leading up to the release of KONY 2012.

She said: "We thought a few thousand people would see the film, but in less than a week, millions of people around the world saw it. While that attention was great for raising awareness about Joseph Kony, it also brought a lot of attention to Jason - and, because of how personal the film is, many of the attacks against it were also very personal, and Jason took them very hard.

"He did some irrational things brought on by extreme exhaustion."

A later update from Danica which was posted on the Invisible Children blog read: "We would, again, like to make it clear that Jason’s incident was in no way the result of drugs or alcohol.

"The preliminary diagnosis he received is called brief reactive psychosis, an acute state brought on by the extreme exhaustion, stress and dehydration."

An online statement immediately after the incident from Invisible Children CEO Ben Keesey said: “Jason Russell was unfortunately hospitalised... suffering from exhaustion, dehydration, and malnutrition.

“He is now receiving medical care and is focused on getting better. "

Named after Joseph Kony, the leader of the Lord’s Resistance Army (LRA), Kony 2012 shows the war-torn country through the eyes of a former LRA child soldier called Jacob.

More than 30,000 children are believed to have been abducted by the rebel group, with the male children being forced to bear arms, and the females being used as sex slaves. The group has also slaughtered hundreds of thousands of civilians in central Africa.

Invisible Children is calling for an international effort to arrest Kony, disarm the LRA and bring the child soldiers home.

A statement on the website reads: "We seek to rebuild schools, educate future leaders and provide jobs in Northern Uganda. We are the motivated misfits and masses redefining what it means to be an activist."

Kony, a former altar boy, is wanted on 33 criminal charges, including 12 counts of crimes against humanity, murder, enslavement and rape.

The LRA began its attacks in Uganda in the 1980s, when Kony sought to overthrow the government. Since being pushed out of Uganda several years ago, the militia has terrorised villages in Central Africa, AP reported.

The film, which features Russell and his son Gavin, has been viewed more than 100 million times.

Celebrities including Angelina Jolie, Rihanna, Nicole Ritchie and Stephen Fry have all backed the campaign.
