The organization announced the sequel March 29 by changing its Facebook cover photo to an image that says "KONY 2012 Part II, premiering April 3."
An Invisible Children spokesperson told Mashable the cover photo is wrong. In fact, the sequel won't be released until later this week.
The original 30-minute documentary has been viewed more than 86 million times on YouTube and more than 17 million times on Vimeo.
KONY 2012 Part II promises to go more in-depth about the intricacies of the conflict in Uganda, responding to critics of the film who say the organization distorted and simplified realities about Joseph Kony and the LRA.
Invisible Children's director of ideology Jedidiah Jenkins told Reuters the sequel will include more voices from the countries where Kony and the LRA are currently based, such as the Central African Republic and the Democratic Republic of the Congo.
Invisible Children has also been criticized for pushing web "slacktivism" -- the concept of sharing links rather than acting. To counter those critics, Invisible Children has planned a day of volunteering in local communities April 20, which it calls "Cover the Night."
