Invisible Children, the organization behind the viral "Kony 2012" video, released a sequel.

The 20-minute film is called "Kony 2012 Part II: Beyond Famous". It attacks Ugandan warlord Joseph Kony and also addresses critics who claimed that the first documentary "oversimplifies facts about the more than two-decade-old Central African conflict."

One thing the film didn't address is creator Jason Russell's recent hospitalization. The 33-year-old had to get treatment in March after a meltdown where he was shown on video running through the street in his underwear.

Russell's wife said he had suffered a "brief psychosis" blamed on the attention he received from the first film which registered than 86 million views on YouTube.
